Lannan is expected to compete with Daisuke Matsuzaka, Jenrry Mejia and others to be the team's fifth-starter.
"The Mets told me that I'd go out and compete, and that's what I plan on doing," Lannan said.
In mid-January, the Mets signed Lannan to a minor-league contract with an invite to major league spring training. The deal can be worth $1.5 million if he makes the major league team with another $2 million available in incentives. He can opt-out of his contract if he’s not on the MLB team by June 15 (Sherman, Jan. 25).
In 14 starts with the Phillies in 2013, Lannan, 29, went 3-6 with a 5.33 ERA, allowing 86 hits and 27 walks with 38 strikeouts in 74 1/3 innings. He underwent knee surgery in late August and missed the remainder of the season.
For his career, Lannan has put up solid fifth-starter type numbers. With a career 4.12 ERA and a 1.432 WHIP, he's not blowing anyone away, but he showed consistency prior to his injury-plagued 2013. His strike out and walk rates are unimpressive, but he keeps the ball on the ground.
Overall, in his seven seasons Lannan has put up an ERA+ of 99 which is just a hair below the league average of 100 and is more than serviceable for the back of the rotation (Dillon Gee's career ERA+, for comparison, is 95). He's never pitched out of the bullpen, so his value as a long man is a big question mark. He should not be counted on for filling that role. At 29, Lannan's upside at this point is minimal, though lefties often develop slower than righties. When healthy, he can throw a lot of innings and give you league average numbers, a valuable asset for any team.
Ideally, he'll be a great depth guy with the last spot in the rotation won definitively by a health Mejia, but the Mets could do much worse to round out their starting five in anticipated of Montero and Syndergaard.
