Syndergaard yielded five runs on nine hits and three walks while striking out nine over five frames Tuesday against the Phillies. He didn't factor into the decision in the Mets' 7-6 win in 11 innings.

The Mets have watched Syndergaard and co-ace Jacob deGrom labor through both of their last two turns, with the typically dominant duo failing to turn in a quality start in any of those four outings. For his part, Syndergaard attributed his recent struggles to having a difficult time gripping the ball, per the Associated Press. Thanks to a team off-day Thursday, Syndergaard will get a five-day break until his next turn Sunday in St. Louis and may use the extra time off to tinker with his mechanics.
