How the Red Sox Are Limiting Home Runs
The Red Sox caught us all by surprise by jumping out to an incredible start en route to an early-season lead atop the AL East. As Tony Wolfe wrote, the strong performance was largely thanks to consistent run-scoring and a dominant bullpen. Fast-forward to mid-May, and Boston is still there, first in the division and continuing to climb up various weekly Power Rankings (including our own). As impressive as the Red Sox have been at the plate, though, the rotation seems to have been overshadowed. I get it; there’s not a lot of name brand recognition. Their two best starters from 2019, Chris Sale and Eduardo Rodriguez, pitched a grand total of 0 innings in 2020. But after taking three of four from the Angels over the weekend, the Red Sox lead the American League in FIP (3.29) among starting pitchers.
Leading the charge is Nathan Eovaldi. His most recent start extended his streak without giving up a homer to 50 innings; he is the only qualified starting pitcher who has yet to do so. That helps make up for a modest 4.50 ERA and strikeout-per-nine rate of 8.46; his FIP is 2.15. Since he’s been in Boston, Eovaldi has struggled with home runs, allowing an average of 1.86 per nine over the past two seasons. That makes sense, as he’s always allowed a lot of balls to be put in play with a penchant for giving up the occasional dinger. But so far this season, the expected value in terms of xwOBA on those balls suggests that Eovaldi is eliciting softer contact, which is supported by his peripherals.
