"I'm not too happy about it," Gonzalez said. "But, it's better to get a step back than two or three. It's important for me to get healthy and be 100 percent for the next start."
Gonzalez threw a side session of fastballs Thursday afternoon while wearing a bandage on his thumb, which is not permitted during games. Orioles manager Buck Showalter said Gonzalez would ideally pitch for either Double-A Bowie or Triple-A Norfolk on Tuesday or Wednesday before returning to Baltimore on May 19 or 20.
"You have to be able to throw a breaking ball; you have to be able to throw a changeup," Showalter said. "You have to be able throw all these pitches, and he can't do it."
Burnett, 25, joined the Orioles earlier this season, from April 22-24, but did not make an appearance. In six relief appearances with the Tides, he is 1-0 with a 0.96 ERA, adding eight strikeouts and no walks. Claimed by the Orioles off waivers from Toronto on April 12, Burnett went 4-4 with a 3.52 ERA in 67 appearances for Minnesota in 2012.
Because the Orioles need a starter for Saturday's game at Minnesota, Burnett's latest stint could once again be a short one.
Right-hander Steve Johnson started the season on the DL with a back injury and is now at Triple-A Norfolk. After Thursday's game, Showalter said he expected to recall Johnson from Norfolk to make Saturday's start against the Twins.
