Webb’s Groundball Machine at Oracle Park
Webb enters with a 2.89 ERA and a 1.08 WHIP. His sinker generates a 58.7% groundball rate, the highest among qualified National League starters.
At Oracle Park this season: 2.41 ERA across 71 innings. He has allowed three home runs at home. Total. He induces double plays at a rate of 1.6 per nine innings.
The Red Sox rank 22nd in groundball-adjusted offensive output. Their lineup struggles against high-spin sinkers. Webb’s sweeper complements the sinker, generating whiffs at a 34.2% clip against right-handed hitters.
Gray: The Veteran Craftsman
Gray, 36, has rebounded from a rough April. His last six starts: 1.98 ERA, 41 strikeouts in 36.1 innings. He is throwing his curveball 38.4% of the time, a career high.
His road numbers this season: 3.12 ERA in 61 innings. Left-handed hitters are batting .198 against him, thanks to a changeup that fades away at 84 mph.
Fenway Park’s dimensions are irrelevant here. This is Oracle Park, and Gray’s fly-ball profile plays well in the spacious gaps. He has a 2.9 K/BB ratio since July 1.

Betting Preview: Why the Under Is the Smart Play
OutKick’s analysis labels both starters “locked in.” The numbers support that framing.
The Red Sox are batting .212 against sinker-heavy right-handers in August. The Giants are hitting .198 against curveball-dominant veterans in the same stretch. Neither offense has seen a comparable arm in the past week.
The moneyline has San Francisco at -135, Boston at +115. The run line sits at Giants -1.5 (+150). The under 7.5 is the strongest play here, given the combined 4.3 expected ERA of the two starters.
The bullpens are equally sharp. San Francisco’s relievers have a 2.98 ERA since August 1. Boston’s pen is at 3.11. Late-inning scoring should be minimal.
