According to the Associated Press, via ESPN.com, the Mets have signed outfielder Bobby Kielty, right-handers Tony Armas Jr. and Matt DeSalvo, and left-hander Valerio de los Santos to minor league contracts.
All four are invited to spring training. Kielty, 32, hasn’t appeared in the majors since 2007. DeSalvo, 28, pitched just two games out of the Braves’ bullpen last year. De los Santos made two starts for the Rockies last season, but spent most of 2008 in Triple-A. He’s 9-13 with a 4.57 ERA in nine major league seasons. Armas, 30, appeared in three games with the Mets last season.
