The read

Fenway hosts the getaway game with Boston chasing a sweep after victories of 11-1 and 9-4. The Red Sox have owned the series, but Arizona is finally handing the ball to the pitcher capable of changing its direction, and I’m taking the Diamondbacks at plus money.

Brandon Pfaadt enters with 20.2 IP and 0 ER over his last three starts, and he owns a 1.73 road ERA with Arizona going 5-1 in his six road starts. This Boston lineup presents plenty of right-handed traffic, the side against which Pfaadt has held hitters to a .212 average and .581 OPS. The Red Sox have produced a .248 average and .715 OPS against right-handed pitching, while Arizona has been markedly better against lefties at .274/.783. Payton Tolle has been outstanding himself—his last three starts produced a 1.35 ERA—but this is a legitimate handedness matchup for the Diamondbacks. Corbin Carroll owns a .329 average and .996 OPS against left-handed pitching, while Gabriel Moreno carries a .365 average and 1.068 OPS over his last 15 days.

Boston’s bullpen is the danger. It has allowed only 2 ER in 15.1 IP over the last three games, while Arizona’s relief corps has surrendered 12 ER in 11.1 IP. That makes Pfaadt’s length central to the wager: he has completed at least six innings in each of his last four starts, giving Arizona a route around the portion of its staff that unraveled earlier in this series. If the Diamondbacks can reach their higher-leverage options, Brandyn Garcia owns a 2.52 ERA and Juan Morillo a 2.37 ERA. The bullpen disparity is real, but +146 compensates me for it. My read calls for Arizona to reverse the series behind Pfaadt and win, so I want the moneyline rather than paying -162 for a +1.5 cushion.
