The Philadelphia Phillies have announced their probable starting pitchers for their three-game weekend series against the St. Louis Cardinals, which begins Friday, August 21, 2026. The information was reported by Heavy’s Cole Sullivan and updated August 20.
Series schedule and Phillies starters
Date Game Phillies starter Cardinals starter
Friday, Aug. 21 Cardinals at Phillies Jesús Luzardo (LHP) Hunter Dobbins
Saturday, Aug. 22 Cardinals at Phillies Andrew Painter (RHP) Andre Pallante
Sunday, Aug. 23 Cardinals at Phillies Cristopher Sánchez (LHP) Kyle Leahy
The Friday game is scheduled for 6:40 p.m. ET, Saturday at 6:05 p.m. ET, and Sunday’s series finale at 1:35 p.m. ET. The Cardinals’ starters were still officially listed as TBD in the Heavy article because St. Louis was completing its series with Cincinnati on Thursday; subsequent listings identified Dobbins, Pallante and Leahy as the probable Cardinals starters.
1. Jesús Luzardo — Friday
Luzardo gets the opening assignment for Philadelphia. He enters the series at 11–5 with a 3.23 ERA and 185 strikeouts.
His role is particularly important because Philadelphia has relied heavily on its top starters during its recent push up the National League East standings.
2. Andrew Painter — Saturday
Right-hander Andrew Painter is scheduled to start Saturday.
Painter’s season has been considerably more difficult statistically. He is listed at 2–8 with a 6.43 ERA and 71 strikeouts entering the series.
That makes Saturday something of a pivotal opportunity for the young pitcher to provide Philadelphia with a quality outing while the club tries to maintain its momentum.
3. Cristopher Sánchez — Sunday
The series finale features Philadelphia’s standout starter Cristopher Sánchez.
Sánchez enters Sunday with an impressive 16–4 record, 2.51 ERA and 187 strikeouts. Heavy identifies him as the headliner of Philadelphia’s pitching staff, with Zack Wheeler carrying the team’s best ERA at 2.49.
Phillies pitching staff numbers
As reported by Heavy, Philadelphia’s pitching staff had combined for:
61–54 record
4.20 team ERA
1.31 WHIP
1,121 strikeouts
1,015.2 innings pitched
Opponents batting .251
Those numbers illustrate why the rotation has been such an important part of Philadelphia’s season. Sánchez, Wheeler and Luzardo have provided the strongest foundation, while the club has received less consistency from the back end of the rotation.
Phillies enter series on a six-game winning streak
Philadelphia enters the Cardinals series with considerable momentum. The Phillies swept the Miami Marlins, giving them back-to-back series sweeps and six consecutive victories.
After the Miami sweep, Philadelphia’s record stood at 70–58. The winning streak has also significantly reduced the gap between the Phillies and the Atlanta Braves in the NL East. According to Heavy, Philadelphia was 4.5 games behind Atlanta, compared with roughly nine games about a week earlier.
Wild Card position
Even though Philadelphia is chasing Atlanta for the division title, the Phillies remain in a National League Wild Card position.
At the time of the article, if the postseason had begun immediately, Philadelphia would have been forced to travel to Wrigley Field for a best-of-three Wild Card series against the Chicago Cubs, who were sitting at 74–54.
Why this series matters
The Cardinals series represents another important opportunity for Philadelphia to continue its surge.
The rotation gives the Phillies a strong left-handed presence on Friday and Sunday with Luzardo and Sánchez, while Painter gets the middle game. The biggest matchup to watch is Sunday’s finale because Sánchez has been one of Philadelphia’s most reliable starters all season.
The Phillies’ recent six-game winning streak has brought them much closer to Atlanta, so a strong series against St. Louis could further tighten the NL East race while strengthening Philadelphia’s Wild Card position.
In short: Philadelphia goes into the weekend with Luzardo → Painter → Sánchez, a 70–58 record and a six-game winning streak, while trying to close the remaining gap on Atlanta.
