The Red Sox’s Surprising Rotation Anchors

The Red Sox are out to a decent start in 2024. Despite dropping five of their last six, they’re above .500 at 19-18. They’re currently in third place in a division where most observers felt they’d finish fourth or fifth. That’s a credit to a pitching staff that leads the majors with a 2.75 earned run average.

Boston’s bullpen looked solid coming into the year, yet the rotation was more of a question mark. It wasn’t that the group was devoid of talent. It was light on pitchers with a proven track record as starters, though, particularly after Lucas Giolito went down for the season in Spring Training. That left the Sox relying on a handful of pitchers who’d been productive as relievers to shoulder important rotation jobs. They’ve delivered thus far, with Tanner Houck and Kutter Crawford out to particularly excellent starts.

Houck and Crawford are the only members of Boston’s season-opening rotation who haven’t spent time on the injured list. Garrett Whitlock, Brayan Bello and Nick Pivetta have all missed time. (Pivetta returned on Wednesday and Bello could be back by the weekend.) Houck wasn’t even a lock for the Opening Day starting five until Giolito’s injury. By all accounts, the Sox rotation should have struggled to this point.

Instead, they easily lead the majors with a 2.33 ERA. That’s at least partially a reflection of their usage. Only the White Sox — whose rotation has been one of the league’s worst — have allowed their starters to face an opposing hitter for a third time in an outing less often. Alex Cora is getting to the bullpen early, which takes some of the higher-pressure at-bats off the rotation. Yet that doesn’t entirely detract from how effective Boston’s starters have been.

Crawford, 28, has appeared in parts of four seasons. He held a rotation spot from June onward last year, turning in solid if unexciting results. Over 23 starts, he worked to a 4.51 ERA with an above-average 26.2% strikeout rate. It was enough for the Sox to guarantee him a rotation spot even when they expected Giolito would be healthy. He went into 2024 with a season-opening starting job for the first time in his career.

The right-hander has doubled down on last year’s success. Through eight starts, he carries a 1.75 ERA that ranks seventh among qualified starters. He has fanned 24.3% of opponents and is generating swinging strikes at a solid 12.3% clip. Crawford has held opponents to two or fewer runs in seven of his…
