In a Tweet by ESPN’s Buster Olney, he mentions the Houston Astros are working hard on a possible trade involving right-handed pitcher Matt Lindstrom.

The Astros acquired Lindstrom from the Florida Marlins in December 2009 for right-handed pitcher Robert Bono and infielder Luis Bryan.

Lindstrom, 30, was 2-5 with 23 saves and a 4.39 ERA in 58 relief appearances for the Astros in 2010.
