Kodai Senga latest Mets starter to fail to give team length

Carlos Mendoza insists he’s not concerned. But the trend, at this point, has become a concerning one.

This isn’t the version of Kodai Senga that the Mets envisioned anchoring their rotation. That, partially, made them comfortable with not acquiring a starter at the trade deadline.

That he can deliver ace-esque outings — the ones blending length with results — over and over again.

The Mets have other rotation questions to answer, but Senga’s trajectory since returning last month has joined that list.

He allowed four runs on five hits, walked three batters and exited after just four innings and 71 pitches during the 12-6 win over the Giants on Saturday at Citi Field. He has topped 77 pitches just once since returning from a hamstring strain in July. He has allowed three or more runs in three consecutive starts, while issuing eight walks across those 12 innings.

“I’m not worried about him,” Mendoza said. “We’re not worried. But I’m pretty sure he’s frustrated because he wants to go deep in games and he wants to perform. And he will.”
