The Philadelphia Phillies' 2026 season is shaping up to be a tough one, and while fans might be quick to point fingers at the offense or pitching staff, the real culprit behind their struggles might surprise you. Sitting at 14-20, the Phillies are 10.5 games back of the Atlanta Braves in the NL East—a far cry from expectations.

Yes, the bats have been quiet at times, and yes, the pitching has had its moments of inconsistency. Manager Rob Thomson already paid the price, getting fired earlier this season. But according to ESPN's David Schoenfield, who handed the Phillies an F grade for their performance so far, the biggest issue isn't hitting or pitching—it's defense.

"Key stat to watch: The Phillies gave up a .349 batting average on balls in play in April, a historically awful month—and yet gave up the lowest percentage of hard-hit balls in the majors," Schoenfield notes. "Sanchez, in particular, has been burned a lot by soft hits. That does point to some serious defensive issues."

That stat is a red flag: the Phillies are allowing a ton of soft contact to fall in for hits, and it's not a coincidence. According to Baseball Savant, the defensive struggles are especially pronounced around Justin Crawford and Bryce Harper. Add in shaky play from Otto Kemp, Trea Turner, Felix Reyes, and Brandon Marsh, and it's clear the Phillies have a leaky glove problem.

It's not all bad news—Bryson Stott and Adolis Garcia have been solid, and Alec Bohm has held his own. But when a superstar like Harper is struggling defensively, it drags the whole unit down. The result is a team that's giving away outs and putting extra pressure on an already inconsistent pitching staff.

For Phillies fans hoping for a turnaround, the message is clear: the bats and arms need to improve, but if the defense doesn't tighten up, no amount of offense or pitching will save this season. From the bleachers to the diamond, it's time for the Phillies to field a complete game.
