Back the under 7.5 with Bryan Woo's 1.10 WHIP facing a punchless Boston lineup.

Woo's elite command meets a Red Sox offense that ranks 24th in home runs, with rain looming.

SidePASS, Boston's starter is not confirmed and SEA +104 lacks a clean edge.
TotalBET UNDER 7.5, backed by Woo's command and rain-dampened Fenway.

The de-vigged team totals of 3.7 and 3.8 add to 7.5, meaning the market prices this game right at the number with no obvious gap. Boston sits at -122 as a slight favorite, but the unconfirmed starter makes that price hard to trust. The soft angle is the total, where wet conditions and Boston's weak power give the under an edge over the posted read.

Woo brings swing-and-miss with an 8.99 K/9 and rare walks at 1.90 BB/9, and his 7.98 H/9 shows he limits hard contact. The Boston starter is probable not confirmed, so any pitching edge on that side is unknowable. Right now Seattle holds the clear, quantifiable arm advantage.

K / G 8.05 #22

Seattle's offense data is not available, so their lineup shape cannot be assessed beyond the projected order fronted by Arozarena and Julio Rodriguez. Boston hits for a solid 0.250 average (7/30) but lacks thump, ranking 24/30 in homers, making them more of a contact stack than a slug-heavy one against Woo. With Boston's opposing arm unconfirmed, Seattle's stack value hinges on an unknown matchup.

Fenway is outdoor with light rain at first pitch, 62F, 96% humidity and a 67% rain chance, all conditions that lean toward suppressing offense or risking a delay. The 6 mph right-to-left crosswind is graded neutral, so no wind boost to run scoring.

DFS Angles

With Boston's opposing pitcher unconfirmed, a mini Seattle stack of Arozarena, Julio Rodriguez, and Canzone offers the best value at 2.36x to 2.63x, though rain risk caps upside.

Woo is the clear DFS pitcher to target given his 8.99 K/9 and 1.90 BB/9 against a low-power Boston bat; the Red Sox starter cannot be evaluated until confirmed.
