The Houston Astros have made significant roster changes as they placed right-hander Cristian Javier on the 15-day injured list due to a right shoulder strain and outfielder Jake Meyers on the 10-day IL with an oblique strain. Javier, who has struggled this season with a 0-1 record and a 12.54 ERA in three starts, was removed from a game against the Colorado Rockies after experiencing shoulder tightness. Meanwhile, Meyers left a recent game with lower back tightness and has recorded a batting average of .243, along with one home run and four RBIs this season. To fill their roster spots, the Astros have selected the contracts of right-hander J.P. France, who had a 2.25 ERA in two appearances last year, and outfielder Taylor Trammell, who played a career-high 52 games last season with a batting average of .197.
