Mattingly Got the Job: Now the Phillies Must Decide Whether 79-55 Was a Turnaround or a Mirage

The most consequential Phillies news of the week wasn't a roster move. It was a press release. Dave Dombrowski dropped the interim tag on Don Mattingly, signing him to a two-year deal covering 2027 and 2028.

It's an easy decision to defend on the surface. Mattingly took over a club that was 9-19 and 10 games under .500 when Rob Thomson was dismissed in late April, and he steered it to a 79-55 record the rest of the way. The Phillies finished 88-74 and clinched a fifth straight postseason berth, a phrase that would have sounded absurd in May.

But that same week, the season ended in the wild-card round at Truist Park — at the hands of Atlanta, of all teams. The Braves, who won the NL East at 94-68, took the series two games to one: 5-3, a 4-3 Phillies win, then 6-2. So the organization's answer to another early exit was continuity in the dugout, with the coaching staff absorbing the reported brunt of the blame. That's a defensible read of a team that also went 11-15 in September and needed to "avoid a historic choke" to even reach October. It is also a bet that the problem was never the man in the chair.

What Mattingly inherits is genuinely good

The rotation is the argument for patience. Cristopher Sánchez (2.91 ERA, 207 innings, 231 strikeouts, 18 wins), Jesús Luzardo (2.86 ERA, 221 strikeouts in 179⅔), and Zack Wheeler (3.00 ERA, 1.05 WHIP, 193 strikeouts) form one of the sport's best top three. Even after Luzardo missed time with shoulder inflammation late in the season, he returned for Game 162 and got the Game 1 ball.

The offense, though, is more reputation than production right now. The Phillies hit .248 with a .716 OPS and struck out 1,319 times. Over their final ten games they hit .215 with a .667 OPS. Kyle Schwarber's 45 homers and .857 OPS came with 220 strikeouts and an expiring contract — the single biggest offseason question facing Dombrowski, who has publicly promised an "open-minded" winter. Bryce Harper played all 162 games and produced a .380 on-base percentage, but 29 homers is a different tier than his peak. Luis Arraez's .310 average was a real asset, and a sprained ankle kept him off the wild-card roster entirely.

The number that actually matters: 4.18

That's the bullpen's season ERA, paired with a 1.334 WHIP and eight blown saves. In a short series, a bullpen that leaks runs erases the advantage a Wheeler-Sánchez-Luzardo front provides. Late-season injuries have left the Phillies scrambling for innings two years running, and the relief corps is where the gap between "division contender" and "series winner" lives.

The organization's own power rating offers an interesting frame: 12th in the league at 0.292, but up four spots and 0.108 points from the prior week, with no key players docked. The underlying quality is real. The results in October weren't.

Mattingly has two years to close that gap. The rotation gives him a puncher's chance every night. The bullpen and a Schwarber decision will determine whether 79-55 reads as a turnaround or a statistical artifact of a soft schedule — and whether the Phillies' fifth straight playoff trip becomes a sixth, or the last one for a while.
