In a role reversal, the Mets start the promising rookie pitcher, while the Cubs start a veteran lefty who started out great but has been fading of late. Matthew Boyd. 13-8, with a 3.20 ERA, 1.11 WHIP. Bad News: Has been lights out at home. 11-1, 2.45 ERA, 0.925 WHIP. Good News: He hasn't been as effective in the second half. 4.74 ERA, 1.245 WHIP. His three starts in September are even worse. 6.00 ERA, 1.533 WHIP. He's at 174.1 IP, after pitching only 21 innings in 2024, and 71 innings in 2023. So he, like Peterson, may have hit the wall. Despite the role reversal, the pitching matchup isn't lopsided like last night. Boyd, though fading, hasn't been nearly as bad as Peterson. And Tong, while promising, hasn't had nearly the success as Horton.
