"Obviously I didn't want to give up the run, but it's one of those things where I felt like I made a lot of quality pitches," said Holland, who was placed on the 15-day disabled list April 21 with a left rib bone bruise.
Holland gave up a leadoff single, and while he was retiring the next three batters, the runner moved up on a wild pitch and scored on a passed ball by catcher Julio Rodriguez.
"I haven't thrown to him much and I'm not a guy that throws a lot of pitches in the bullpen to warm up, so he didn't get to see me a lot," said Holland. "I think that played into the wild pitch and the passed ball, but overall, I think it went really well."
Manager Ned Yost watched the outing on MiLB.TV via computer in his office and was impressed by Holland's command and his velocity, which reached 94 or 95 mph. The hit was a bouncer up the middle.
"He got the first hitter 2-0, threw him a slider and he hit a four-hopper right up the middle," Yost said.
The run tagged Holland with the loss in Tulsa's 9-4 victory. He'll start again Thursday.
