Mets SS Amed Rosario launched his third homer of the season Tuesday night during the team's 7-4 loss to the Diamondbacks at Citi Field.
Rosario broke D-backs starting pitcher Patrick Corbin's 20 1/3 inning scoreless streak as he sent a hanging breaking ball into the left field seats during the bottom of the fifth inning. He also hit his third triple of the year, which drove in Dominic Smith.
Rosario, 21, who finished the night 2-for-4 with two RBI, is hitting .326 during his last 43 at-bats.
"I've just matured a little bit being up here," Rosario recently told The Post's Kevin Kernan. "My strike zone is a little too big right now and we are working on that."
Matthew Cerrone (Twitter | Instagram | About Me): It's been an uneven road so far for Rosario, who has made some slick plays in the field and had a couple of big hits, but also made rookie mistakes and struggled at times with the bat. Overall, though, I see a kid improving and slowly getting used to everything that goes along with starting at shortstop for a big-league team in New York surrounded by veterans, pressure, and expectations. It's no easy task.
Thankfully, he has Jose Reyes, who went through the exact situation 13 years ago.
In terms of improving, he's still allowing for too big of a strike zone. He has to tighten it up, which I know he's been working on with hitting coach Kevin Long. It's been better during the last five games, evident by his improved production and striking out (on average) one fewer time each game.
The fact is, based on what he's done so far, he projects to be a 4.5 WAR player, according to FanGraphs.com, which would have made him the third-most productive shortstop in the National League last season -- ranking ahead of Cubs SS Addison Russel. And that, by the way, is as-is, not with improvement, which he's bound to have as he plays more and gets in to next season.
The point is, while he may look raw right now, he's already producing at a level worthy of being an elite major-league shortstop, let alone an elite prospect. In time, as he learns to shrink his strike zone, shorten his swing, and as he learns the league's infields, ballparks, pitchers and hitters, he's going to be as terrific as everyone hopes he'll be.
