After keeping rookie star Cody Bellinger out of the lineup the last three games, the Dodgers put him on the disabled list Tuesday because of a sprained right ankle he suffered Saturday. “The cost of trying to get him through it versus the upside, I just think it’s smart to be on the cautious side,” manager Dave Roberts said. In Bellinger’s spot, the Dodgers recalled reliever Josh Ravin from triple-A Oklahoma City. Ravin has been up twice this season, recording one save and posting a 3.38 earned-run average in 5 1/3 innings over four appearances. Hitters have only two hits in 18 at-bats against the right-hander. Bellinger injured the ankle while jumping to catch a ball near the warning track at Comerica Park in Detroit.
