Pitchers very similar numbers, but BAL much better positioned to exploit Alexander's split (LHBs .344 wOBA, .364 xwOBA) than HOU is to exploit Young's, who nearly no-hit them last time out. HOU offense (16 wRC+ L7 days) and bullpen (worst estimators MLB by nearly half a run L30 days) are both spiraling.
