TORONTO — A big day by the bottom of Texas’ batting order helped the Rangers overcome an injury to third baseman Adrian Beltre in the start of their postseason play. Robinson Chirinos hit a two-run homer against David Price, Rougned Odor added a solo shot and the Rangers beat the Blue Jays 5-3 Thursday in their AL Division Series opener as postseason baseball returned to Toronto for the first time in 22 years. Beltre came in the third with a strained muscle in his lower back and Toronto’s Josh Donaldson in the fifth after he was kneed in the head while sliding in an attempt to break up a double play. An MRI exam confirmed Beltre had a strained back but no structural damage, general manager Jon Daniels said. Texas will have Joey Gallo and Ed Lucas travel from its Arizona Fall League team in case Beltre needs to be removed from the roster, a decision that also would rule Beltre out of the AL Championship Series. Blue Jays slugger Jose Bautista hit a solo homer in the sixth, then left with a sore right hamstring after popping out in the eighth and was replaced in right by Dalton Pompey. Delino DeShields and Beltre hit RBI singles to give Texas a 2-0 lead in the third. Beltre, injured when sliding into second base as Prince Fielder hit into an inning-ending double play in the first, had difficulty running and was replaced by rookie Hanser Alberto in the bottom of third.
