§ 01The analysis
Start with the gap on Cade Cavalli: a 4.00 ERA underwritten by a 4.54 xERA, which reads the contact he allows as softer than his runs show and points to tighter run prevention ahead. On the other side, Connelly Early's 3.59 ERA is propped up by a 4.30 xERA, a 0.71-run gap, and his last 5 starts carry a 4.82 FIP over 26.7 innings. The peripheral split widens out further: Cavalli's FIP is 3.10, Early's is 4.41. The pitch-mix matchups line up the same way. Cavalli leans on 39.8% breaking pitches against a Boston lineup running a .261 xwOBA on breaking pitches across 836 plate appearances, and that lineup has been cooling off against right-handers over 694 plate appearances on the year. Early counters with 55.1% fastballs into a road offense ranked 5 of 30 in OPS at 0.74 and posting a .356 xwOBA against fastballs across 1766 plate appearances. The catcher steals 0.9 called strikes per 100 taken pitches above league baseline, and Boston is missing Isiah Kiner-Falefa and Marcelo Mayer to the 10-day IL.
§ 02The call
The risk is the recent shape of things. Boston is 7-3 over its last 10 on a 5-game winning streak, their pitching staff ranks 5 of 30 in ERA at 3.69, and Early's last 5 starts split from a 5.40 ERA early to a 2.25 ERA most recently. The bullpen edge tilts the wrong way too: Aroldis Chapman holds a 2.19 ERA over 24.7 relief innings with 16 saves and only 132 pitches thrown in three days, while Gus Varland carries a 6.25 ERA over 31.7 relief innings. These sides have also met 5 times recently with the road team 0-5.
