Tylor Megill began Saturday’s game fresh off his first-career loss, thanks to Miami, looking to get back on track against another division opponent in Philadelphia.

The 26-year-old retired the first nine Phillies who came to the plate, including strikeouts of Bryce Harper and J.T. Realmuto. (Those two ended 0-for-4 versus Megill.) It was the exact opposite of his last start versus the Marlins where Megill allowed the first three batters of the game to reach base and the fourth to hit it out of the ballpark.

Megill was able to wiggle through a fourth inning, aided by a generous bunt pop out by Jean Segura and another strikeout of Realmuto to end the inning, after an Odubel Herrera double started the frame.

But then came a disastrous fifth.

Brad Miller greeted Megill in the fifth with a huge solo homer to right center followed by an Alec Bohm double. Jeremy Hefner came out to talk to the righty, and Megill was able to retire two of the next three. But the lineup turned over, and Herrera, who the Mets have largely been able to keep in check this year, hit a first-pitch three-run home run to right. He gave it a little stare.

The Mets let Megill try to get out of the inning, but Segura poked an infield single to second base and Megill’s day was done ahead of a third at-bat with Bryce Harper.

His final line ended at 4.2 innings, four runs (all earned), five hits, a walk and five strikeouts after allowing just one hit through the first four innings.

Megill said there was “frustration” in the clubhouse with how they’ve been playing, but they’re trying to “stay positive.”

“A loss is a loss,” he said. “Don’t like it.”

To be fair to the rookie, he’s been put an a pretty pressure-packed position. He started the year in Double-A and come July became one of the Mets’ only consistent starters. He’s handled it extremely well, despite his last two sub-par starts.

He has a 3.20 ERA, though, across his first nine career starts with a 4:1 strikeout-to-walk ratio. He’s shown deGrom-esque poise in tense moments but also completely reasonably has let a couple innings get away from him. He’s also shown a deGrom-esque poise despite lack of run support from teammates.

His next start lines up for Friday at Citi Field (in the black uniforms) versus the Los Angeles Dodgers. Welcome to the big leagues, bud.
