Ramirez received a cortisone injection in the AC joint of his right shoulder June 11 and missed the next day's game. He had played in every Dodgers game since then, but the shoulder was sore over the weekend in San Diego and Ramirez told trainers he felt it when he swung a bat during Monday's 5-3 loss to the Kansas City Royals.
Previously, Ramirez had felt pain in his shoulder when he threw but not when he hit. He did not take on-field batting practice with the Dodgers on Tuesday at Kauffman Stadium.
In the final year of his contract, Ramirez is batting .269 with 11 home runs and 46 RBIs.
"At this point, I'm not that concerned, because it seems like Hanley's had a little bit of this over a couple years," Dodgers manager Don Mattingly said. "It's not the first time I've ever heard about him feeling this. We've always been able to get him some treatment, loosen it up and let him go."
Mattingly said Ramirez has not undergone an MRI or other medical tests on the shoulder in the past couple of days.
"At this point, I don't look at this like it's going to land him on the [disabled list]," Mattingly said.
