He topped out at 89 mph on the ballpark radar gun during a 25-pitch first inning, and with four more walks, he has issued 10 free passes in six official Cactus League innings.
"I don't know how to put it into words. I just didn't feel like myself today," Rogers said. "I never got into a groove."
Rogers is one of three relatively inexperienced candidates for two openings in Milwaukee's rotation. Of the three -- Rogers, Mike Fiers and Wily Peralta -- only Rogers is out of Minor League options. He has been dealing with a bout of "dead arm" recently, perhaps a result of reporting to early to Maryvale Baseball Park.
"I've been putting in the work," Rogers said. "I've just got to continue to work through it. My last bullpen [session] was outstanding, probably my best of the spring, but I wasn't able to transfer it over. I've just got to get my consistency back. That will come with more repetitions."
Manager Ron Roenicke was puzzled after the Brewers' 12-3 loss, but said he was keeping an open mind until the club gets closer to its roster decisions.
"I can't make a judgment on that right now -- I mean, the way he's throwing right now, he needs to get better, yes," Roenicke said. "I don't know if he's feeling better. I don't know. I talked to him after his last outing, so we'll see what's going on."
