Zack Wheeler returned to the Phillies in late April and immediately looked like a front-line starter again. He covered 62.2 innings with a 2.01 ERA after missing time with venous thoracic outlet syndrome.
The rebound gave the Phillies back one of the few pitchers in the NL who can still pair volume with run prevention. Wheeler and Cristopher Sánchez now give the club a rotation front that can shorten games when both are working on schedule.
Phillies and Zack Wheeler
Philadelphia signed Wheeler to a five-year, $118 million contract before the 2020 season, and the deal has aged into one of the best in franchise history. In seven seasons in Philadelphia, he has posted a 2.85 ERA, a level that keeps the club anchored to him even after a serious arm diagnosis.
His 2025 season was cut short by venous thoracic outlet syndrome, and he was shut down at the back end of that year. At the beginning of the 2026 season, he was set to miss a chunk of time, then continued his rehab into the first month of the big league season before returning in late April.
Baseball Savant and FanGraphs
The surface line after his return was strong enough on its own. Wheeler struck out 62 hitters in 62.2 innings, allowed just 5.5 hits per nine, and carried a career-low 0.846 WHIP while stranding 90.7% of baserunners.
The deeper numbers backed it up. He posted a 3.25 xFIP from FanGraphs, a 3.02 xERA from FanGraphs, and a 3.36 SIERA this season, while his fastball sat at 95.1 mph and his four-seamer reached the 97th percentile in fastball run value through Baseball Savant.
Wheeler and Cristopher Sánchez
There is one wrinkle in the line that keeps this from being a pure victory lap. Wheeler is striking out 8.9 hitters per nine, his lowest mark since 2020, even though the rest of the profile remains elite.
That gap is the part the Phillies have to watch as the 2026 season continues. If the strikeout rate holds where it is and the run prevention stays near 2.01, Wheeler remains exactly what Philadelphia needed when he came back in late April: a top-of-rotation arm who can stabilize the front of the staff alongside Cristopher Sánchez.
