Momentum in the American League Division Series might have shifted to the Toronto Blue Jays, as Texas Rangers third baseman Adrian Beltre officially was ruled out of Friday’s Game 2.

Beltre injured his back while sliding into second base during Thursday’s 5-3 win over the Blue Jays.

Words can’t describe how important Beltre is to the Rangers’ success. In the regular season, he posted strong numbers to help anchor Texas’ lineup. There is no timetable for Beltre’s return, but based on his facial expression — after he hit an RBI single in the third inning — it didn’t look good.

Hanser Alberto replaced Beltre after he exited Game 1.
