Although he was born in San Diego, Robbie Grossman was brought to Houston early enough to buy into the rivalry against Dallas. The Cy-Fair graduate has spent most of his life here, and he shares the Bayou City’s dislike for that other major Texas city up north. Grossman doesn’t hide his disdain for the Texas Rangers. On Friday night he delivered the biggest blow with a two-run home run in the eighth inning to propel the Astros to a come-from-behind 4-3 victory over the Rangers at Minute Maid Park. “They beat up on us for a while, especially last year,” Grossman said after going 3-for-3 with a two-run home run and a walk. “It’s always good to beat them.” Time was running out on Grossman and the Astros late Friday night. On a personal level, the young outfielder needs to state his case because Dexter Fowler and George Springer are nearing returns from the disabled list. Grossman delivered for the Astros with a two-run home run to left in the eighth. Gregorio Petit, who entered in the sixth inning after All-Star Jose Altuve exited with neck discomfort, added an RBI double to cap the three-run inning with the run that proved to be the difference.
