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.

Props on this game
2Brandon PfaadtUNDER 2.5 Pitcher Earned Runs Pitcher Earned Runs+100
LActual 5
Pfaadt has stayed under this number in eight straight starts, including 20.2 scoreless innings across his last three. He has completed at least six innings in four consecutive outings and owns a 1.73 road ERA.
Boston has scored 20 runs in this series, but this is a different matchup. Pfaadt has limited right-handed hitters to a .212 average and .581 OPS, while the Red Sox are sitting Adley Rutschman after he went 4-for-9 with a homer in the first two games. Boston's .715 OPS against right-handed pitching is ordinary, and even money is enough for me to back Pfaadt's current form.
Gabriel MorenoOVER 1.5 H+R+RBI H+R+RBI+102
WActual 4
Moreno has cleared this number in 10 of his last 15 games, batting .365 with 13 RBI over that span. He also owns a .312 average and .973 OPS in day games and enters after driving in all four Arizona runs Tuesday.
Batting third gives him several ways to cash. Ildemaro Vargas and Corbin Carroll both own averages above .325 against left-handed pitching, creating RBI opportunities, while Moreno's recent extra-base damage gives him a path to clearing the line with one swing. I want the combined production prop at plus money.
