Astros' Brice Matthews: Dealing with back injury

The Astros announced that Matthews was placed on Double-A Corpus Christi's 7-day injured list Friday due to back muscle spasms, Matt Kawahara of the Houston Chronicle reports.

For the second time this season, Matthews has been shut down with a back issue, as he had previously missed most of May due to what the Astros had described as low back discomfort. The infielder returned to action for High-A Asheville on June 1 before moving up to Corpus Christi two and a half weeks later. Since getting promoted to Double-A, Matthews had slashed .225/.344/.441 with six home runs and 10 stolen bases across 131 plate appearances.
