Mets sign right-hander Mitchell to Minors deal

NEW YORK -- The Mets signed right-hander D.J. Mitchell to a Minor League contract, the team announced on Monday. Mitchell will report to extended spring training in Port St. Lucie, Fla.

Mitchell, 25, appeared in four games out of the bullpen for the Yankees last season, posting a 3.86 ERA. The Mariners subsequently acquired him as part of the trade that sent Ichiro Suzuki to the Bronx, and Mitchell made one start for Seattle's Triple-A Tacoma affiliate this season before being designated for assignment.

Over five Minor League seasons, Mitchell is 47-26 with a 3.53 ERA in 103 games -- 96 as a starter. He should give the Mets a measure of rotation depth after the team designated left-hander Aaron Laffey for assignment on Sunday.

Marcum impressive with solid spring outing

NEW YORK -- Right-hander Shaun Marcum fired five scoreless innings in an extended spring game on Monday in Port St. Lucie, Fla., keeping him on track to make his Mets debut on Saturday.

Marcum, who has been on the disabled list since Opening Day due to nerve irritation in his neck, struck out four and allowed three hits with zero walks. He threw 52 pitches in the game, then additional pitches after in the bullpen.

The Mets next need a fifth starter on Saturday against the Phillies, and manager Terry Collins has indicated that Marcum will be that pitcher if healthy. Left-hander Aaron Laffey, who served as the fifth starter earlier this season, was designated for assignment on Sunday.

Marcum, 31, signed a one-year deal with the Mets last winter worth $4 million plus incentives. He went 7-4 with a 3.70 ERA in 21 starts for the Brewers last weekend, missing a month due to a partially torn ulnar collateral ligament in his right elbow. Shoulder and elbow issues have forced him to the disabled list multiple times throughout his seven-year career with the Blue Jays and Brewers.
