Houston Astros shortstop Jeremy Peña has been diagnosed with a fractured rib after being hit by a pitch from Cade Horton of the Chicago Cubs. The injury was initially undetected after the game, revealing itself only after further scans. Peña, who boasts a .322 batting average this season, will be placed on the 10-day injured list, retroactive to the injury date. As the team embarks on a six-game road trip, a corresponding roster move will be announced.
