Pitcher Kodai Senga was masterful again and the Mets offense did just enough in Ronny Mauricio’s debut to beat the Mariners 2-1 at Citi Field.

Mauricio made his MLB debut and handled himself well. A natural shortstop, the infielder started at second base and made every defensive play hit his way including a nifty double play in the third inning.

But he was just as impressive at the plate. In his first at-bat, Mauricio launched a double 117 mph off the bat. It’s the hardest hit ball by a Met this season. In his second at-bat, Mauricio struck out swinging on three pitches, but picked up a single in his third AB. The infielder finished 2-for-3.

Mauricio became the first Met to have multiple hits in his MLB debut since Steven Matz — yes, the pitcher — in June 2015.

Brett Baty returned as the third baseman. His offensive struggles continued but that could have been a product of Mariners starter Logan Gilbert who was on his game.
