The read

Overcast skies and an 8 mph wind coming in from right greet these teams after Monday’s 10-inning shootout. Seattle finally found its offense, yet Boston still erased an 8-5 deficit and won at Fenway.

Bryan Woo is the key to Seattle’s case, but his 5.96 ERA across 74.0 road innings is difficult to overlook. Seattle is 4-10 in his 14 road starts, and his allowed OPS is .712 against left-handed hitters compared with .594 against right-handed hitters. Boston starts three left-handed hitters and two switch-hitters, including Roman Anthony, Mickey Gasper and Wilyer Abreu in the first four spots.

Jedixson Paez is the risk. He has no 2026 MLB starts and is expected to work approximately 55–65 pitches, so Boston does not own the starting-pitcher advantage. I’m accepting that uncertainty because Boston has the better relief group behind him. The arms on tonight’s roster have a combined 2.80 ERA and 1.12 WHIP, compared with Seattle’s 3.90 ERA and 1.27 WHIP. Garrett Whitlock did not pitch Monday, while Gabe Speier and Seranthony Domínguez have worked on consecutive days for Seattle.

Neither bullpen has performed well lately, but Boston also owns the stronger season-long foundation: 75-63 with a +85 run differential, versus Seattle at 64-74 with a -73 differential. At a manageable home price, I’m backing Boston’s lineup and late-inning options to overcome the uncertainty surrounding Paez.
