Embarrassing sweep should make Phillies think twice about buying at MLB trade deadline

Amid an otherwise-excellent season, Zack Wheeler struggled on Monday while pitching a season-low three innings in an 8-7 loss, raising concern over his immediate future, while 2026 All-Star Jesus Luzardo fizzled on Wednesday. Aaron Nola, who has a 5.79 ERA over the past two seasons, turned back the clock on Tuesday but still picked up his ninth loss of the season in a 1-0 Marlins win.

An extended midseason hot stretch may have given Philadelphia false confidence. After a dismal 9-19 start to the season, the Phillies fired manager Rob Thomson and proceeded to go 45-24 over their next 69 games, improving from last in the NL East to second and two games back of the division-leading Atlanta Braves.

Since then, the Phillies have lost their past four series — against the Marlins (55-54), New York Yankees (61-46), Los Angeles Dodgers (67-40) and New York Mets (46-62) — since the All-Star break while going 3-9 overall. Philadelphia's pitching staff has a combined 4.54 ERA, allowing 97 hits, including 19 home runs and 39 walks with 112 strikeouts in 105.1 innings during the span.

The offense hasn't been much better, producing a .240/.303/.413 slash line with a troubling 26.4 percent strikeout rate.

Interim manager Don Mattingly, while first providing a spark, has hit a lull, and the decision Wednesday to turn to reliever Seth Johnson, who entered the day with a 5.51 ERA, with runners on first and second in the seventh backfired when he allowed both inherited runners to score.

The Phillies have been wholly unremarkable over the past two weeks and hardly appear one big trade away from World Series contention, particularly with internal division possibly growing.

Before Wednesday's series finale with the Marlins, Mattingly fired back at comments from two-time MVP Bryce Harper, who told reporters the previous night, "I think we need some help" amid the team's slump.

"Players like being GMs and making calls and spending other people's money," Mattingly said. "When you say something about our team, then you're saying something about one of our players that you don't like.

"I always look at it internally," Mattingly challenged. "You know, 'I've got to get better. We've got to get better.'" 

He kind of has a point. If a team already with the fifth-highest payroll in baseball can't put it together, perhaps adding to that core is unwise. 

After appearing to have turned the corner, Philadelphia is right back where it was at the start of 2026. While the Phillies could certainly use reinforcements, as bad as they've looked of late, no amount of assistance will save them from a lackluster fate.
