AJ’s Angles
These are the top MLB betting trends and systems for today’s games, handpicked by VSiN Analyst AJ Makinen.
Top MLB Resources:
(957) CHICAGO-AL (14-33) at (958) TORONTO (20-25)
Trend: Jose Berrios is 21-4 (+9.95 units) as a home favorite of -190 or higher in the last five seasons
System Match: PLAY TORONTO (-205 vs CWS)
Trend: Jose Berrios is 22-5 (+13.80 units) in home day games in the last five seasons
System Match: PLAY TORONTO (-205 vs CWS)
Series #15: Boston at Tampa Bay, Mon 5/20-Wed 5/22
Trend: Boston has lost 16 of its last 17 (5.9%, -15.03 units) games at Tampa Bay
– The ROI on this trend is -88.4%
System Matches: FADE BOSTON (-108 at TB)
DK MLB Betting Splits system #7: There was a unique system that developed last year when majority handle betting groups backed home favorites with less wins on the season. This was a terrible scenario for bettors, as they were just 128-137 (48.3%) for -73.71 units and an atrocious ROI of -27.8%. There’s a lot of common sense to this not doing well as well, since lesser team is being favored just because it is at home or has a better starting pitcher working.
System Matches: FADE ST LOUIS (-125 vs BAL)
Home teams off blowout losses are solid bets to rebound versus that same opponent
Teams playing at home against the same team after a blowout loss of seven runs or more have been solid wagers over the last 5+ seasons, going 329-304 (52%) for +37.47 units of profit. This represents an ROI of 5.9%.
System Matches (PLAY): ATLANTA GAME 1 (-125 vs SD)
Strategies Using MLB DraftKings Betting Splits Data
One of the most touted features on the VSiN.com website, and a feature that we believe to be a fantastic resource for bettors is the betting splits pages. These are the pages that we have built utilizing the data that DraftKings so graciously provides to us, detailing the breakdowns of the money and ticket splits for point spreads, money lines, and totals.
In an article published on the VSiN.com website prior to opening day, Steve Makinen outlined 10 different systematic strategies for successfully using the DK Betting Splits Data that developed in the 2023 season. Here are the systems and qualifying plays for today’s games as of 11:00 a.m. ET, based on Steve Makinen’s betting splits systems. These can and will change, so continue to track and qualify the systems up until first pitch for best usage.

As a general rule, acknowledging the approximate -10% returns on all majorities, if adopting the use of the betting splits this season, opt to fade majorities unless shown otherwise in one of the systems below to be a profitable follow angle.
DK MLB Betting Splits system #1: When 90% or more of the handle was on the home side of an MLB money line wager last season, this supermajority group did quite well, going 125-45 (73.5%) last season for +36.19 units and an ROI of +21.2%. This obviously beats the overall majority handle ROI return by almost 32%. If you see 90% or more of the handle backing a host in an MLB game this season, it’s a solid bet to follow it.
System Matches: PLAY HOUSTON (-205 vs LAA)
DK MLB Betting Splits system #2: Majority bets groups proved to be at least reasonably successful when not too many of them got on a side last season, and in fact, the benchmark was 60%+. When the majority percentage figure of bets landed in the 51%-59% range, these groups finished the season with a record of 221-193 (53.4%) for +0.88 units and an ROI slightly above 0%. This isn’t the rate of return that a professional bettor is looking for, but it is not a loss, and it is definitively better than the overall ROI of -8.9%.
System Matches (SLIGHT PLAY ALL): ATLANTA GAME 1 (-122 vs SD), BOSTON (-108 at TB)
DK MLB Betting Splits system #3: Majority handle bettors were pretty sound last year when getting behind huge home favorites of -250 or higher. This group went 117-33 (78%) last season for +20.38 units and an ROI of 13.6%. This is a pretty strong rate of return and a tremendous winning percentage, but I would caution as to getting too deep into this one if it turns the other way.
System Matches: NONE YET TODAY
DK MLB Betting Splits system #5: Majority handle bettors were worse overall in interleague games in 2023, going 374-314 (54.4%) for -81.67 units and an ROI of -11.8%. This is over a full percentage point worse for return and an indication that bettors have trouble gauging the strengths/motivations of the teams when playing unfamiliar opponents.
System Matches (FADE ALL): MINNESOTA (-166 at WSH), BALTIMORE (+105 at STL)
DK MLB Betting Splits system #6: Majority handle bettors were profitable last year when betting the lowest totaled MLB games, going 181-154 (54%) last season for +11.6 units and an ROI of +3.5% on games with posted totals of 7.5 or less. Recognizing that the majority bettors’ preferred option is Over bets, most of these wins came as games surpassed their posted numbers.
System Matches: PLAY OVER in: CWS-TOR
PLAY UNDER in: SD-ATL GAME 1, BOS-TB
DK MLB Betting Splits system #7: There was a unique system that developed last year when majority handle betting groups backed home favorites with less wins on the season. This was a terrible scenario for bettors, as they were just 128-137 (48.3%) for -73.71 units and an atrocious ROI of -27.8%. There’s a lot of common sense to this not doing well as well, since lesser team is being favored just because it is at home or has a better starting pitcher working.
System Matches: FADE ST LOUIS (-125 vs BAL)
DK MLB Betting Splits system #8: There was a distinct up & down pattern of performance for majority handle bettors by month last season. March/April ROI was -1.3%, May was a brutal -20.6%, June climbed back up to -6.9%. July slipped to -15.1%, followed by an August return of -3.5%, and finally a September/October drain of -16.7%. Diving deeper into specifics, these three different systems will be tracked in 2024:
– Majority handle bettors in May were just 207-201 (50.7%) for -85.15 units and an ROI of -20.6%
System Matches: FADE ALL MAJORITY HANDLE TEAMS THIS MONTH
DK MLB Betting Splits system #10: When 85% or more of the bets were on either side of an MLB run line wager last season, this “super” majority group did far better than the overall numbers, going 282-235 (54.5%) last season for +0.45 units and an ROI of 0%. Again, this is clearly just a very minimal return but considering the major losses in all of the MLB betting categories, it beats the overall majority bets ROI return by almost 8% and if it continues in 2024, will at least keep bettors in the game.

MLB Bullpen Systems
The following systems and qualifying plays are from the weekly update series on handicapping MLB teams using Steve Makinen’s bullpen strength ratings.
The easiest way to play the bullpen system
Better-rated bullpen teams that were not favorites of -190 or higher or were -190 or higher and had a winning percentage of 19% or higher went 1200-916 in the ’23 regular season for +45.66 units, a 2.2% season-long return on investment. So far in 2024 through 5/5, they are 263-213 for +0.3 units. For the last three weeks in a row, results have picked up nicely. Considering the average MLB bettor playing every game has lost -32 units, this system is providing a huge advantage even as it is performing a bit below its 2023 standards.
System Matches: MILWAUKEE, TAMPA BAY, NY YANKEES, CHICAGO WHITE SOX, DETROIT, CLEVELAND, MINNESOTA, BALTIMORE, ATLANTA GAME 1
Fade better bullpen overpriced favorites of -190 or higher when the win percentage difference of teams is <19%
In games of the 2023 regular season in which the team with the Steve Makinen better rated bullpen was listed as a favorite of -190 or higher and had a winning percentage less than 19% higher than the opponent, that team owned a 171-106 record, but for -84.47 units. That represented an ROI of -30.5%! So far in 2024, these teams are 30-16 for -4.32 units and a ROI of -9.4%. However, the ROI dropped 44% over the past 38 days.
System Matches (FADE ALL): LA DODGERS (-230 vs AZ), HOUSTON (-205 vs LAA), ATLANTA GAME 2 (-225 vs SD)
Overpriced better bullpen without a big starting pitcher edge angle was the 2023 regular season’s most lucrative system
In combining starting pitcher differences in looking at games with -190 favorites or higher, there’s was a huge opportunity to be selective in fading overpriced favorites. Specifically, when the starting pitcher difference between the better Steve Makinen rated bullpen team was less than 20, those big favorites went just 80-74, but for -87.21 units in the regular season! This angle is 25-15 since opening day 2024 and has lost -7.13 units, an ROI of -17.8%.
System Matches: FADE HOUSTON (205 vs LAA)
Better bullpen underdog teams were solid wagers all season long
A frequent and profitable system in the 2023 season, and prior to that as well, arose when the team with the better SM Bullpen Ratings played as an underdog. Moneyline underdog teams with better bullpen ratings for the season were 341-346 for +72.72 units. The ROI of this angle produced a healthy 10.6%. In the early part of the 2024 season, these teams have produced a 101-125 record, for -9.17 units.
System Matches (PLAY ALL): CHICAGO WHITE SOX (+170 at TOR), DETROIT (-102 at KC), BALTIMORE (+105 at STL)
Worse bullpen teams continue to struggle in extending winning streaks
In 2023, it was found that fading teams with lesser SM bullpen ratings that were looking to extend winning streaks was also a strong strategy. On two-game winning streaks, the teams with worse Steve Makinen Bullpen Ratings in a matchup were 240-249 for -28.51 units, an ROI of -5.8%. Worse bullpen teams on 3+ game winning streaks finished the regular season with a record of 99-119 for -16.61 units. The ROI on that system finished at -7.6%. For 2024 so far, these two-game teams have gone 37-46 for +0.24 units after a poor three-week stretch of 23-28 for -6.77 units. The three-game teams are 29-31 for +1.89 units. The three-game angle was 15-18 for -1.61 units since 4/22.
System Matches: 2-games – FADE SAN DIEGO GAME 1 (+102 at ATL)
3-games – FADE KANSAS CITY (-118 vs DET)
Better bullpen teams are capable of building lengthy winning streaks
In conducting a study of teams with better bullpens on winning streaks last season, when looking at teams with better Steve Makinen Bullpen Ratings looking to extend three-game winning streaks, I tracked that those teams that went 241-168 for +11.33 units, a respectable ROI of 2.7%, a slight improvement on the overall record of the “easiest way system.” For 2024, better bullpen teams on a three-game winning streak are 61-45 for +0.31 units through Sunday, 5/18, after a 37-33, +7.41 units stretch over the last five weeks.
System Matches (PLAY ALL): LA DODGERS (-230 vs. AZ), NY YANKEES (-142 vs. SEA), CLEVELAND (-130 vs. NYM)
Better bullpen teams thwart losing streaks
Better bullpen teams on 3+ game losing streaks went 119-79 for +22.2 units in the 2023 regular season. The ROI for the season closed at 11.2%! There have been 57 plays on this angle so far in 2024 through 5/19, and these teams are 32-25 for +1.87 units.
System Matches (PLAY ALL): CHICAGO WHITE SOX (+170 at TOR), MINNESOTA (-166 at WSH), ATLANTA GAME 1 (-122 vs SD)
MLB Extreme Stats Systems
The following systems and qualifying plays are from the article titled MLB Extreme Stats Systems, detailing eight MLB betting trend systems for betting teams based upon noteworthy stats they accumulated in their previous game
Home teams off blowout losses are solid bets to rebound versus that same opponent
Teams playing at home against the same team after a blowout loss of seven runs or more have been solid wagers over the last 5+ seasons, going 329-304 (52%) for +37.47 units of profit. This represents an ROI of 5.9%.
System Matches (PLAY): ATLANTA GAME 1 (-125 vs SD)
“9” is a magic run number for fading a team in the next game
Since 2018, doesn’t matter if the team is playing at home or on the road, if they scored nine runs or more in the previous contest, they are posting a winning record at 1508-1408 (51.7%), but oddsmaker overpricing has resulted in a loss of -171.87 units. This represents an ROI of -5.9%, which is significant in the grand scheme of baseball daily betting.
System Matches (FADE ALL): SAN DIEGO GAME 1 (+105 at ATL), BOSTON (-108 at TB), HOUSTON (-205 vs LAA)
Road teams that didn’t score well last game are a bad bet in the next outing
You’re going to want to consider fading teams playing on the road that scored 2 runs or fewer in their last contest. They have proven to be bankroll-busting options over their last 4+ seasons. These road teams are just 1382-1800 (43.4%) for -180.15 units and an ROI of -5.7% since the start of the 2019 season.
System Matches (FADE ALL): CHICAGO WHITE SOX (+180 at TOR), MINNESOTA (-166 at WSH)
Home teams that did score well last game are also actually a bad bet in the next outing
Going back another season to 2018, home teams coming off a game in which they scored five runs or more are winning more often than not at 3038-2659 (53.3%) but they have been a loser for bettors at -400.77 units and an ROI of -7%.
System Matches (FADE ALL): NY YANKEES (-142 vs. SEA), WASHINGTON (+140 vs. MIN), TORONTO (-218 vs. CWS), CLEVELAND (-130 vs. NYM), KANSAS CITY (-118 vs. DET), HOUSTON (-205 vs. LAA)
Home team hitting slumps don’t last long
MLB Home teams coming off a game in which they had four hits or fewer have rebounded quickly with an 855-738 (53.7%) record in the follow-up contest since the start of the 2018 season. This has resulted in a profit of +15.90 units for backers and an ROI of 1%.
System Matches (PLAY ALL): ATLANTA GAME 1 (-125 vs. SD), CLEVELAND (-130 vs. NYM), TAMPA BAY (-112 vs. BOS)
