The Astros announced on Saturday that they have come to terms with seven players on one-year contracts and invited two Minor League catchers to Spring Training as non-roster invitees.

Left-hander Fernando Abad, outfielder Brian Bogusevic, catcher Jason Castro, right-hander Paul Clemens, infielder Chris Johnson, right-hander Fernando Rodriguez and infielder Brett Wallace each signed a one-year deal with Houston.

Abad, Bogusevic, Johnson, Rodriguez and Wallace saw significant time with the Astros last season. Castro, the club's first-round pick in the 2008 First-Year Player Draft, missed the entire '11 season while recovering from right knee surgery, while Clemens, who was acquired from the Braves at last year's non-waiver Trade Deadline, went 8-7 with a 3.81 ERA in 26 Minor League starts between Double-A and Triple-A.

Houston also announced the invitations of catchers Rene Garcia and Chris Wallace to Major League camp.

Garcia, 21, hit .242 with 11 doubles and 27 RBIs in 86 games for Class A Advanced Lancaster last season and is spending his second successive Spring Training with the big club.

Wallace, 23, hit .271 with 20 home runs and 78 RBIs in 102 games between Class A Lexington and Double-A Corpus Christi in 2011, finishing third among all Astros Minor Leaguers in home runs and RBIs.
