Dellin Betances took a step back on Thursday, and that was a good thing.

The Yankees’ setup man threw a simulated two innings on a back field at George M. Steinbrenner Field to re-discover his mechanics without a radar gun over his shoulder. After watching him struggle on Sunday, the third time he threw in a week and the first time on just one day’s rest, pitching coach Larry Rothschild wanted him to work on his mechanics.

“I think Sunday he was reaching for (velocity), trying to find it and got out of whack,” Rothschild said. “He looked good today.”

Betances threw 28 pitches, 19 for strikes in six at-bats.

“In the first inning I didn’t really feel like I was letting it rip,” Betances said. “The second inning, I felt like I was letting it go.”
