Astros claim OF Martinez off waivers from Mets
Martinez hit .227 (5 for 22) for the Mets last season with one home run - at Houston against Bud Morris on May 13.
The 23-year-old Martinez spent most of the year at Triple-A Buffalo and hit .260 with eight homers and 30 RBIs. He has a .183 career big league average with two homers and 12 RBIs in 131 at-bats over parts of three seasons.
To make room on the 40-man roster Wednesday, the Astros designated right-hander Henry Villar for assignment. He was a combined 4-5 with a 5.45 ERA last year at Triple-A Oklahoma City and Double-A Corpus Christi.
