Amed Rosario, New York Mets

There was a lot of learning on the job for Amed Rosario in 2018. Overall, he struggled to an 85 wRC+ and .676 OPS in 592 plate appearances, but it certainly was a step forward when compared to his short rookie campaign (75 and .665, respectively, in 170 plate appearances).

What’s worth pointing out, though, is that the young shortstop made significant improvements in August and September. Over his final 239 plate appearances, he posted a .731 OPS and 102 wRC+. He produced a wRC+ above 100 in each month, which was the first time he’d accomplished such a feat as a big leaguer.

Part of this was likely possible because of 26.7% line-drive rate, but this was still legitimate progress the Mets had been waiting to see all season. With top shortstop prospect Andres Gimenez moving through the farm system, it’ll be crucial to keep taking steps forward this season.

One of the things he can focus on is continuing to improve his plate discipline. After posting a 45.5% chase rate, 18.1% swinging-strike rate, and 1.8% walk rate during that abbreviated rookie year, those numbers improved to 41.2%, 12.8%, and 4.9%, respectively, this past year.
