Astros activated RHP Nate Pearson from the 15-day injured list.

Pearson figures to operate in a versatile swingman-type role, typically handling long relief situations, after missing the first seven weeks of the season recovering from elbow surgery. The 29-year-old was one of the top pitching prospects in baseball earlier in his career with the Blue Jays, but never quite panned out as a traditional starter or reliever. He can be safely ignored for fantasy purposes at the moment.
