The Mets agreed to sign Casey Fossum, according to Adam Rubin of ESPNNewYork.com. Fossum gets a minor league deal and an invitation to minor league Spring Training, according to Andy Martino of the New York Daily News (Twitter links).
Fossum, 33, spent last season in Japan after spending nine seasons in the Major Leagues. He has a 5.45 ERA with 7.0 K/9 and 3.7 BB/9 in 786 innings for the Rays, Red Sox, D'Backs, Mets and Tigers. He started regularly early on in his career, but has been working exclusively out of the 'pen since 2008.
Fossum's rate stats are slightly better against left-handed hitters (7.1 K/9, 3.1 BB/9, 41.2% ground ball rate), but he hasn't shown a pronounced platoon split over the course of his career.
