Houston general manager Ed Wade said last week any remaining additions to the club would likely be limited to signing players to non-roster contracts with invitations to Spring Training. The Astros' 40-man roster is full after trading for reliever Matt Lindstrom, signing reliever Brandon Lyon and third baseman Pedro Feliz and re-signing backup outfielder Jason Michaels within the past 10 days.
Lindstrom, 29, cost Houston three lower-level Minor Leaguers, but he throws hard and had experience closing in Florida. Lyon went 6-5 with three saves in 65 games for Detroit last season and saved 26 games and had a 4.70 ERA in 2008 with Arizona.
"What you've got is two guys that have Major League experience, and they're coming around, and we'll stick them right into our bullpen," Mills said. "It's pretty special. Any time you can get guys with experience and arms like that, and they have the ability to do things, it's a plus. It's nice to see the ballclub come together a little bit."
