Astros sign eight to Minors contracts

Righty Sadowski made six starts last season for Giants

INDIANAPOLIS -- Astros general manager Ed Wade on Tuesday announced the signing of eight players to Minor League contracts with invitations to Spring Training -- four pitchers and four position players.

Among the pitchers signed was right-hander Ryan Sadowski, who went 2-4 with a 4.45 ERA last season in six starts for the Giants, including seven scoreless innings against the Astros in his second career start. He was 6-3 with a 5.04 ERA in 18 games (17 starts) at Triple-A Fresno.

Also signed were right-handers Roy Corcoran, Casey Daigle and Gary Majewski, a Houston native. Daigle spent all of last season at Triple-A Round Rock, where Corcoran finished the season. Majewski is a reliever who has appeared in 229 career Major League games in five seasons.

The Astros also signed third baseman-first baseman Chris Shelton, who hit .231 in nine games for Seattle last season before spending the majority of the season at Triple-A Tacoma. He has a career .273 average with 37 homers and 124 RBIs in 299 games, including 18 homers and 59 RBIs for the Tigers in 2005.

Outfielder Alex Romero, second baseman Drew Meyer and infielder Oswaldo Navarro were also signed to contracts.
