Tampa Bay Rays’ Bullpen Splits and the 3-Batter Rule
By Seth Carter
Bullpen Splits – Page Two
Diego Castillo RHP – 2019 Batting Average Against
vs. Right: .205
vs. Left: .271
Diego Castillo faced 106 lefties and 184 righties. Righties posted a .295 OBP while lefties posted a .340 against Diego Castillo in 2019.
Colin Poche LHP – 2019 Batting Average Against
vs. Right: .190
vs. Left: .167
Colin Poche was dominant against both lefties and righties. Despite his 4.70 ERA Poche only allowed a .277 OBP to righties and a .276 OBP to lefties. If you can look past his not-so-great ERA, his underlying numbers tell a different story. Poche struck out 12.5 batters per nine while only walking 3.3 per nine. He posted a 1.01 WHIP
Oliver Drake RHP – 2019 Batting Average Against
vs. Right: .216
vs. Left: .147
Oliver Drake faced 115 righties and 104 lefties last season. Of his 19 total walks last season, 17 came against right-handed hitters. Drake actually went against conventional wisdom by allowing a .865 OPS against righties and just a .360 against lefties.
Jose Alvarado LHP – 2019 Batting Average Against
vs. Right: .282
vs. Left: .194
Alvarado had a very small sample size last year, but for his career, he’s actually been better against right-handed hitters than lefties. Lefties have slashed .235/.324/.296 against Alvarado while right-handed hitters have slashed .195/.297/.284. As you can see, he’s been incredibly effective against both. If he’s healthy and back to form, it doesn’t matter what side of the plate you stand on.
Chaz Roe RHP – 2019 Batting Average Against
vs. Right: .258
vs. Left: .227
Chaz Roe allowed a .351 OBP against righties and a .370 against lefties. He limited the damage by only allowing .358 and .318 slugging percentages, respectively.
