1:55pm: The Astros are close to acquiring reliever Matt Lindstrom from the Marlins, writes Joe Capozzi of the Palm Beach Post. Capozzi notes that the Marlins have been close on other deals that failed to materialize, however. The Astros are also considered a finalist for Rafael Soriano; I imagine they won't get both.
Lindstrom, 30 in February, lost his closer job to Leo Nunez midseason as he dealt with an elbow strain. He's arbitration-eligible for the first time.
