SEATTLE -- Mookie Betts was out of the Los Angeles Dodgers lineup on Tuesday after getting hit on the right forearm a night earlier, but manager Dave Roberts doesn't expect it to be a long-term issue.

Roberts said X-rays on Betts' arm were negative after the former MVP took a fastball from Seattle closer Rafael Montero off the inside of his right forearm in the ninth inning of Monday's 4-3 Mariners victory. Betts remained in the game after getting hit.

Roberts said Betts was receiving treatment.

"I was hoping that it would be something soft tissue, as opposed to, you know, the wrist or the elbow or something like that," Roberts said. "I guess best-case scenario. There was an exhale once he wanted to stay in there. So that's part of it, the soreness, but I think that we dodged a bullet there."

The Dodgers beat the Mariners 1-0 on Tuesday. The team has a day off on Wednesday before opening a four-game series with division rival San Diego on Thursday at Dodger Stadium.

Betts is hitting .292 and already had one of the signature defensive moments of the season with his game-ending catch in the ninth inning last Saturday in a win over San Diego.

Chris Taylor started in center field for the Dodgers.
