The Seattle Collapse Ends a Nine-Game Winning Streak
On August 24, 2026 at T-Mobile Park, Philadelphia starter Zack Wheeler was pulled after four innings of a 9-2 loss to the Seattle Mariners. He surrendered eight earned runs on nine hits, including four home runs (two to Cal Raleigh, one each to Julio Rodríguez and Cole Young) and issued five walks. Wheeler threw 103 pitches, 94 of them before the fifth inning, and failed to record an out in the fifth. The defeat snapped the Phillies’ nine-game winning streak and dropped them to 3½ games behind the NL East leader.
Recent Performance Trend
- Over his last six starts Wheeler’s ERA has risen to 8.51, a sharp contrast to the 2.16 ERA through his first 16 starts.
- He has allowed four or more runs in four of those six outings and has not reached the sixth inning since July 21.
- In his most recent four starts he has walked 15 batters, the most in a four-start span since April 7, 2019.
- The four home runs given up on August 24 tie his career-high set on May 29, 2026.
Official Statements & Responses
Phillies’ interim manager Don Mattingly said Wheeler’s “stuff still seems good” but that “command was probably the biggest thing” affecting his performance. Wheeler insisted he is physically fine, stating, “Healthy, strong. Everything’s there. Just got to zone back in and figure it out.” He added his fastball feels solid but his off-speed pitches are “not there.”
Catcher J.T. Realmuto pointed to “big misses, and then more pitches in the heart of the plate,” describing how missed locations make the ball appear larger to hitters. The organization plans to review video and data before Wheeler’s next outing.

On-the-Ground Observations
Reporters noted Wheeler’s first inning unraveled quickly: after walking leadoff batter Randy Arozarena, he allowed a single to Dominic Canzone and a three-run splitter homer to Julio Rodríguez. Cal Raleigh followed with a fastball-up home run, and a second Raleigh blast plus a solo shot by Cole Young came after Wheeler was sent back out in the fifth. The Mariners’ early barrage accounted for most of the eight runs, while Philadelphia’s offense managed only a run-scoring forceout by Alec Bohm and a solo homer by J.T. Realmuto.
Conflicting Reports & Gaps
Some analysts attribute Wheeler’s decline to lingering effects of his thoracic outlet syndrome surgery and a prior rib removal, suggesting a possible loss of stamina. Others, citing velocity data (fastball averaging 94.9 mph), argue that his arm health remains intact and that the primary issue is command and pitch location. No definitive cause has been identified, and the team has not ruled out pitch-tipping as a factor.
What’s Next
The Phillies will send Aaron Nola to the mound on the following day’s road game, while Wheeler is scheduled to meet with coaches on August 25, 2026 to address the identified problems. The outcome of that review will shape his role as the rotation’s ace as Philadelphia continues its push for a postseason berth.
