Over Starling Marte‘s last 13-games, the outfielder has four doubles, two triples, and four home runs. Marte has been on fire, and has continued to do so since coming off of the bereavement list a week ago.

The Mets hoped that the two-time Gold Glove award winner would continue his dominance at the plate as well, when they signed him to a four-year $78 million deal in the offseason.

On the year Marte is hitting .286 with six home runs, 31 RBIs with seven stolen bases. On Tuesday he started the game with a two-run home run to follow up a four-RBI performance from the night before.

“He’s been a little more selective, he’s really seeing the ball on the white part of the plate a lot more,” manager Buck Showalter said. “I think he’s really trusting himself and letting the ball travel, not rush through the hitting pattern, so to speak.”

Marte’s hard-hit percentage has jumped from 25.4% in the month of April to 38.2% in May with his launch angle raising from five degrees in April to 10 degrees in May, meaning he’s hitting way more line drives. Marte has at least one hit in now 13 of his last 15 games and has produced 27 runs during that time frame (16 runs scored and 11 RBIs.)

The Mets’ offense emerged beautifully during May, and Marte’s been right in the thick of it.

“I’ve been really studying how they’ve been pitching me,” Marte said, “and now that we’re a month-and-a-half, a little bit more, into the season it’s due that I’m able to make the adjustments.”

Marte has especially noticed how righties are pitching him. He’s slashing .304/.347/.464 against right-handed pitching in 138 at-bats. Interestingly he’s recorded all seven of his stolen bases when a right-hander is on the mound.

Marte also enjoys playing for the home crowd. At Citi Field, his OPS is almost 300 points higher than on the road.

The Mets were able to roll in April with Marte off to a slow start. Now after batting .340/.359/.570 in the month of May the Mets offense is turning into a true juggernaut.
