Game Overview
On Sunday, June 21, 2026, the New York Mets will play the Philadelphia Phillies at Citizens Bank Park, 7:20 p.m. ET. NBC will broadcast the game; Peacock will stream it. Left-hander David Peterson (3-5, 5.91 ERA) starts for the Mets, while right-hander Zack Wheeler (6-1, 2.01 ERA) starts for the Phillies. The contest is the series finale on Father’s Day.
Pitching Matchup
Peterson’s season includes seven starts, 64 innings, a 5.91 ERA, 3.76 FIP, 1.625 WHIP and a 70 ERA+. His last strong outing was a one-hit shutout versus Miami in late May; since then he has allowed nine runs on nine hits and three homers in 6 2/3 innings. Wheeler, back from injury, has a 2.01 ERA over 62 2/3 innings, a 3.39 FIP, 0.846 WHIP and a 221 ERA+. He gave up four runs to the Dodgers on May 29 but has limited opponents to three runs in the following 19 innings. Wheeler’s career line against the Mets is 5-5 with a 3.36 ERA.
Recent Series Context
The Mets entered the series after a 6-4 win on Thursday, powered by Juan Soto’s two solo homers and a defensive catch that denied Bryce Harper. That victory ended a stretch of back-to-back losses for the first time since mid-May. Saturday’s game featured Freddy Peralta (5-5, 3.90 ERA) versus LHP Cristopher Sánchez (8-3, 1.82 ERA). The Mets have repeatedly lost the first two games of a week before winning the third, a pattern noted in recent previews.
Stakes and Impact
Both clubs seek momentum. The Mets, at 30-39 on Father’s Day, aim to break a .500 stretch that could affect playoff positioning. The Phillies, 41-35, look to cement a winning record while adding left-hander Kyle Backhus to the bullpen. Backhus, who posted a 1.17 ERA in 7.2 Triple-A innings, is slated for activation early next week, addressing a left-handed relief need.
Official Statements & Responses
Interim manager Don Mattingly said Backhus “is expected to rejoin the roster soon,” without confirming a date. The Phillies have not named a Monday starter, leaving the decision dependent on Wheeler’s Sunday performance and bullpen usage.
Criticism & Opposition
Analysts note the Mets’ pitching inconsistency, citing Peterson’s high ERA and WHIP as a liability against a Phillies staff that has limited runs in recent outings. Reliance on a struggling rotation could hinder the Mets’ chance to win the finale.
