"It was good to get my feet wet [against the Braves], I'd never played in a stadium that big with that many people," Bauer said. "I wasn't out there a whole lot, I didn't get a chance to learn a whole lot, but I'll be more comfortable with the energy and the routine this time."
Allowing two runs on five hits to the Braves, the right-hander was lifted early due to a minor groin injury that Bauer says is no longer bothering him. He also dealt with high temperatures in Atlanta.
"When I looked down the bench, he was very disappointed in himself, but we talked to him about it, there was no disappointment for us," D-backs manager Kirk Gibson said. "He busted his tail. It was just time to get him out of the game. He's got great stuff, we know that, we just have to get him to apply it correctly.
"He's very competitive. I feel good about the way he'll figure things out."
Entering the season as Arizona's No. 1 prospect, Bauer will likely remain on a pitch count when he takes the hill on Tuesday.
Meanwhile, Andrew Cashner will start for the Padres, ready to build off of his last outing against the Astros.
Retiring 19 of the first 20 batters he faced last Thursday, the converted reliever tossed a career-high 6 1/3 innings in the no-decision. Cashner held Houston to two runs on two hits, while striking out nine and walking only one.
Cashner's fastball hit 100 mph in the first inning and stayed consistent throughout the game, clocking above 96 into the seventh.
"I felt like I had better stuff when I was in the Minors and I felt like I still had my fastball there in the seventh," Cashner said after the game. "I feel like my legs are really strong right now and I can hold my velocity."
Padres: Amarista hitting stride
In a groove during his last five games, second baseman Alexi Amarista has nine hits in his last 16 at-bats, including four home runs.
In Monday's game against the D-backs, Amarista went 3-for-5 with a home run, double and three RBIs.
"We are starting to get some guys back and it takes a while to integrate themselves back in," Padres manager Bud Black said. "There's a continuity factor going on now with the position players. On the pitching side, things have smoothed out a little bit."
Left-hander Eric Stults, on the 15-day disabled list, retroactive to June 4, with a strained left lat muscle, threw a bullpen session on Monday and will throw another on Wednesday. After that, the club will make a decision on what to do.
"He's ready to throw off the mound, so we brought him over here to put our eyes on him," Black said. "He's getting closer to being active."
D-backs: Blum comes off DL; McDonald goes on
The D-backs activated infielder Geoff Blum from the 60-day disabled list and placed infielder John McDonald on the 15-day disabled list on Monday, retroactive to June 25, with a strained left oblique.
Blum only had 11 at-bats to start the season before going on the DL on April 18 with a strained left oblique. In 12 rehab games for Triple-A Reno, the 39-year-old hit .237 with three doubles, a homer and eight RBIs.
McDonald was originally in the D-backs' lineup on Saturday in Milwaukee, but was scratched beforehand. Because he hasn't played in more than a week, the 37-year-old could only miss another week's worth of games if all goes well in his rehab.
"He came to me on Saturday and said he couldn't play," D-backs manager Kirk Gibson said. "It had been bothering him."
On the disabled list with a shoulder injury retroactive to June 17, D-backs pitcher Joe Saunders will throw a simulated game on Tuesday at Chase Field and hopes he can skip a rehab assignment and move directly back into the rotation.
The D-backs are 35-3 this season when leading after eight innings.
Before Monday, The D-backs had won seven of their last nine games against the Padres at home and were 10-2 in their last 12 games at Chase Field.
Padres outfielder Chris Denorfia is a career .333 (25-for-75) hitter against the Diamondbacks. His five home runs against Arizona are his highest total against any opponent.
