Biggest Surprise: SP Jenrry Mejia
Jenrry Mejia has seemingly been a top prospect in the Mets' organization forever, as it was all the way back in 2010 that he made his debut in the team's bullpen as a 20-year-old rookie. The right-hander made 33 appearances that season, pitching to a 4.62 ERA, but that quick bump from the minors seemed to do more harm than good over the long-term.
He missed 2011 due to Tommy John surgery and the first half of last season with elbow inflammation. He returned in July to make five starts, though, going 1-2 with a 2.30 ERA and 27 strikeouts in 27.1 innings, before undergoing surgery to remove bone chips from his elbow in August.
He should be ready to go by Opening Day, and he will have a chance at the No. 5 starter spot. If he can stay healthy and win the job, he could finally be in for a big season in 2014.
Biggest Disappointment: LF Curtis Granderson
The Mets got their man this offseason in their search to improve outfield production, signing Curtis Granderson to a four-year, $60 million deal just before the winter meetings. The 2013 season was essentially a lost year for the 32-year-old, as a pair of hit-by-pitch injuries limited him to 61 games.
Those were freak injuries, and his durability has never been an issue in the past, so health is not what makes him a potential disappointment. Instead, it's how he changed his offensive game during his time with the Yankees that could make for a poor season.
Granderson was a dynamic all-around offensive player when he was in Detroit, but he turned into an all-or-nothing home-run hitter with a low average in New York. He won't have the short porch in right field to use anymore, and if he can't rework his approach, he could be a major disappointment.
