OAKLAND -- Travis Blackley, who spent most of his down time in the stands at The Coliseum, was traded to the Houston Astros by the Athletics for Minor League outfielder Jake Goebbert following Thursday's 8-2 win over the Mariners.
The A's and Astros open their series Friday night in Houston.
Blackley went 1-1 with a 14.21 ERA in seven games, including two starts, for the A's this spring before he was designated for assignment last Friday.
He allowed 27 hits in 12 2/3 innings for a .450 opponents batting average. Blackley was claimed off waivers from San Francisco last year on May 15 and went 6-4 with a 3.86 ERA in 24 games, 15 starts, with the A's.
He is 7-7 with a 5.37 ERA in 36 career Major League appearances, including 23 starts.
Goebbert spent most of the 2012 season at Double-A Corpus Christi, where he hit .304 with 23 doubles, six triples, nine home runs and 53 RBIs in 114 games.
He also walked 55 times on his way to a .399 on-base percentage. The 25-year-old left-handed hitter also hit .133 in 16 games with Triple-A Oklahoma City. Goebbert is a .285 career hitter with 31 home runs and 237 RBIs in 456 games over four seasons in the Minors.
