He's not a prospect, but don't sleep on Nathan Eovaldi as another young player to watch in the Yankee system this year. The 24-year-old righty is going to be a very important part of the rotation this year, and in a really good piece by Bryan Hoch, he talked about what he's been working on to improve his game: "My goal toward the end of the season, my last two or three games with the Marlins, I was working on a changeup -- kind of like a split-finger [fastball], in a way. It's been feeling great. I felt comfortable with it toward the end of the season last year, and this offseason, I've been able to pick up pretty much where I left off."
Eovaldi's changeup has been the weak link of his offerings over the first few years of his career, so it's good to know that he's made it a top priority. In addition to that focus, Hoch reported that Eovaldi has already spoken with Larry Rothschild, Brian McCann, Joe Girardi, and Chris Capuano, and it sounds like Roth and Big Mac are going to make working with Eovaldi their top priority when spring camp starts.
These are all good things. The Yankees don't make that trade if they didn't see something in Eovaldi, and I'd like to think that Roth and McCann can help bring a lot more out of Eovaldi's arm. His stuff is way too good to have the low strikeout numbers he has and a big part of that is probably pitch location and quality of secondary stuff. McCann will help a lot with the first part and Roth has proven to be a master at tweaking guys to draw more swings and misses out of their stuff. If he can work with Eovaldi to improve his changeup more and Eovaldi gets more comfortable using it in a game, that's only going to make his heater more dangerous.
