Mookie Betts, who turned 32 on Monday, wants to celebrate his birthday with some postseason hitting.

Betts went 0-for-4 in the Los Angeles Dodgers ' 10-2 loss in Game 2 of the NLDS on Sunday. He is 2-for-31 in the club's past three postseason series.

He's also hitless in his last 22 playoff at-bats, tied for the fourth-longest postseason hitless-at-bat streak by a former MVP.

Dave Roberts says he believes Betts' shortcomings in previous postseasons are starting to "bleed in" to his current at-bats.

"I'll have a conversation with him," Roberts said of Betts. "The fact is you can't change the last 'X' amount of postseason games. I understand the burden a player might have. But all anyone is concerned about is right now and how to best prepare yourself mentally for tomorrow night and the first at-bat. So that's going to be basically my message."

Betts estimated taking somewhere in the neighborhood of 400 swings during Monday's workout, including multiple rounds in which he purposely drove pitches to right-center field off a high-velocity pitching machine at Petco Park. 

"If there's another way," he said, "please let me know."
