Boston Red Sox vs Seattle Mariners Prediction, Odds and Picks for Today, 06/17/25

The Boston Red Sox secured their first win since trading Rafael Devers, and they did it in surprising fashion, continuing one of the hottest stretches in baseball. Winners of six straight, Boston’s pitching staff has delivered 19 consecutive scoreless innings, and now Walker Buehler gets the nod. While Buehler’s 5.01 ERA doesn’t jump off the page, he’s been much sharper lately, coming off a solid seven-inning outing against Tampa Bay. His 1.38 WHIP reflects competitive stuff that keeps games within reach. The Red Sox lineup has found a spark even without their star DH, thanks in part to young bats and timely hitting. Roman Anthony got his first major league home run last night…maybe this west coast road trip comes at a good time to get away from the pressure of being at home and around the media. Given their recent form and bullpen dominance, Boston looks poised to keep this tight and capitalize on a Mariners lineup that’s trending downward.

Seattle counters with Bryan Woo, who’s been a bright spot in their rotation all year. Sporting a 3.39 ERA and 0.98 WHIP, Woo has quietly emerged as a reliable strikeout arm with 72 K’s across 82 innings. However, he’s coming off a rough outing where he surrendered five runs to Arizona, and the Mariners’ offense hasn’t offered much help. Julio Rodriguez has been heating up, batting .360 in June, but the rest of the lineup has cooled off considerably. Seattle may have the home-field edge, but with Boston surging and Woo coming off a stumble, the Red Sox +1.5 feels like the better side.
