Eleven straight losses have now come from Philadelphia's fifth rotation spot after a 3-1 defeat to the Yankees, leaving the Phillies 2-6 since the All-Star break and with a third straight series loss.
Five competitive innings from opener Tim Mayza and debuting bulk reliever Brian Keller briefly stabilized that spot, but the Phillies again failed to hit a left-handed starter and managed only a first-inning run.
The tie unraveled in the sixth when Trea Turner misplayed a shallow fly and Cody Bellinger followed with a go-ahead single; Jasson Domínguez added a seventh-inning homer.
Two more errors from Philadelphia underscored a broader slide: the club entered with MLB's worst defensive runs saved, is batting .218 against left-handed starters, and has gotten some of the league's weakest bullpen results since June.
Aug. 3 now looms as a pressure point for the front office, with the Phillies needing rotation help, a right-handed bat, bullpen reinforcements and cleaner defense.
