WASHINGTON — The Houston Astros reinstated infielder Braden Shewmake from the injured list and optioned infielder Raynel Delgado to Triple-A Sugar Land before Monday’s series opener against the Washington Nationals.

Shewmake missed a month with a right adductor strain that landed him on the injured list June 2. Prior to the injury, Shewmake posted a .243/.260/.405 slash line across 28 games for the Astros, who acquired him from the Yankees in a mid-April trade for minor-league pitcher Wilmy Sanchez.

Shewmake made starts at three different infield positions for Houston before his injury. He drew the start at shortstop Monday against Nationals right-hander Miles Mikolas.

Delgado, acquired last month from the Rays for cash considerations, has played in 16 games with the Astros this season, posting a .267/.313/.400 slash line across 33 major-league plate appearances.

The Astros expect to have shortstop Jeremy Peña back from the IL during a series against the Rangers that begins Friday in Arlington. Peña is scheduled to play his first minor-league rehab game Tuesday with Triple-A Sugar Land, manager Joe Espada said, and will be eligible to return from the IL starting Friday.
