Phillies need to add a shutdown left-handed reliever

Phillies relief pitchers — both lefties and righties — have struggled to get left-handed batters out this season. It’s an important area for the Phils to clean up as soon as possible, because the numbers are poor.
Phillies RPs vs. LHHs (MLB Rank)
- 4.75 ERA (7th-worst)
- 5.08 FIP (7th-worst)
- .343 OBP (11th-worst)
- .321 wOBA (11th-worst)
- 5.2 BB/9 (6th-worst)
Phillies LHRPs vs. LHHs (MLB Rank)
- 6.10 ERA (4th-worst)
- 6.91 FIP (worst)
- .418 OBP (2nd-worst)
- .363 wOBA (5th-worst)
- 7.8 BB/9 (3rd-worst)
The Phillies bullpen doesn’t get a handed advantage on left-handed hitters nearly enough, because it lacks the depth to do it. When it does get left-on-left matchups, it doesn’t make much of a difference.
The bullpen ranks in or right outside the bottom third of the Major Leagues against left-handed hitters in all five stat categories and both data sets listed above. We’re looking at less than two months of data, which is less than one-third of the season, so the Phils can still turn this thing around.
Adding one pitcher isn’t going to solve the ongoing struggles against lefties, but it would be a start, because this team could use an upgrade to trot out there in high-leverage situations.
Phillies RPs vs. LHHs in High-Leverage Situations (MLB Rank)
- .347 BA (4th-worst)
- .450 OBP (3rd-worst)
- .612 SLG (5th-worst)
- .439 wOBA (3rd-worst)
- 10.50 ERA (4th-worst)
- 8.64 FIP (4th-worst)
The Phillies bullpen has faced 61 batters in high-leverage situations this season — the third-most of any team. It has allowed 14 earned runs, 17 hits (including four home runs) and nine walks, with only eight strikeouts, in those situations.
Left-handed hitters are slashing .347/.450/.612 against the Phillies ‘pen in high-leverage spots. For context, Mike Trout’s career slash-line is .305/.419/.582. Phillies relievers are making opposing lefties as a group look better than Trout in the most critical situations of a game.
The Phillies need their bullpen to consistently get big outs against the game’s top left-handed hitters, especially the ones in their division.
