On one hand, he allowed a lone hit over five innings, left with a 2-1 lead and recorded his first hit since turning pro. On the other hand, he issued five walks, threw two wild pitches and ended up with a no-decision in the Reno Aces' 4-2 loss to the New Orleans Zephyrs.
"Disappointing. I'm a little, well, not happy with my performance," he said. "I had a couple mechanical things going on for whatever reason and I couldn't make the corrections, so I kept making the same mistakes.
"But I was able to keep my team in it and I competed well. I had good life on the ball, but I had no idea where it was going. My defense backed me up today."
While the bullpen was unable to preserve the lead and give Bauer his second Pacific Coast League victory, the D-backs' top prospect slapped an opposite-field single to right field in the fifth for his first Minor League hit.
"It was my first hit since my freshman year of high school," said Bauer, who was 0-for-16 with three walks and an RBI entering Wednesday's game. "I swung and I was really late on it and hit it off the end of the bat and it rolled along the chalk [up the first-base line]. I'm happy to get the first one out of the way. Hopefully, it won't take six more years for the next one.
"I wanted [the ball], but my first-base coach said I didn't want it. Hopefully, I'll get my first big league one some day."
Bauer threw only 42 of 89 pitches for strikes, went to three-ball counts on half of the 20 batters he faced and uncorked two wild pitches, the second of which scored a run.
The 21-year-old right-hander needed 16 pitches to get through a 1-2-3 first inning and threw 24 more in the second after walking a pair and striking out two.
Bauer had a 21-pitch third inning, arguably his most stressful of the evening.
Kevin Mattison -- the Marlins' No. 11 prospect -- drew a one-out walk, stole second and advanced to third on catcher Ryan Budde's throwing error. Gil Velazquez followed with a ground ball to third base and the Aces caught Mattison in a rundown, with Bauer applying the tag. Velazquez made it all the way to third on the play and scored on a wild pitch to knot the game at 1-1.
Scott Cousins delivered a two-out double and Gaby Sanchez walked, but Bauer retired Sergio Pedroza on a grounder to escape further damage.
"My glove side was weak and my back side hip was not firing very well. It was disappointing, for sure," the UCLA product said. "They're the two adjustments I can normally make, but I couldn't focus and make those changes. I would think about it on the mound, but as soon as I got my sign, I would make the same mistake. It was like washing my hair -- lather, rinse, repeat."
A leadoff walk to Marlins' No. 2 prospect Matt Dominguez produced another threat in the fourth, but Budde threw him out trying to steal second and Bauer set down his final five batters.
In his Triple-A debut on Friday, Bauer carried a shutout into the eighth against Oklahoma City. He finished with a career-high 11 strikeouts, allowing one run on four hits and a walk over eight innings.
It was a near-perfect introduction to life at Triple-A for Bauer, who made the nearly 2,200-mile trip from Alabama to Nevada.
"I packed up my entire apartment and had a couple friends and teammates over and said bye to them," he said. "I got my electric bill transferred and lease sorted, it was definitely a late night. I got to bed at 3 a.m. and I was up at 4 to get out for a 6:25 flight.
"I didn't have a roommate, so I either had to have the clubbie ship it home or bring it with me. I travel pretty light. Most of the stuff was my clothes and music, and that fits in my bags."
The transition to a new apartment in a new city has been a smooth one.
"Most times when moves are made, there is a spare room somewhere. [Third baseman] Ryan Wheeler had an open room, so I moved in with him," Bauer said. "He's great. He's into music, so we get along over that. He's a great guy."
Beau Jones (2-1) tossed a scoreless inning to get the win. Zephyrs starter Alex Sanabia allowed a run on a hit and three walks while striking out two over three frames before leaving with a groin injury.
Cousins and Gil Velazquez both had two hits and an RBI, while Sanchez reached base four times for New Orleans.
Wheeler, Arizona's No. 17 prospect, went 4-for-4 to raise his average to .325. Mike DeMark (3-3) took the loss after surrendering two runs on five hits over 1 1/3 innings.
