He allowed six earned runs over five innings. But since then, Wieland's last two starts have yielded promising results and he will try to continue making progress when he toes the rubber against the visiting Brewers on Monday.
Wieland's second start came against the Phillies, an outing in which he gave up just one run but lost. The 22-year-old suffered a similar fate in his latest start vs. the Nationals when he served up two runs but lost again.
"After those two first two innings at Dodger Stadium, I was pretty comfortable since then," Wieland said. "I've had no nerves. I've just been going out and doing the same thing I've been doing the last couple years."
Wieland will try to put everything together and earn his first career win Monday.
A victory would also put the Padres on the right track to earn their first series win of the season. They have lost six series in a row and split a four-game set so far in 2012.
Juxtaposing the rookie's youth for the Brewers on Monday is 35-year-old Randy Wolf.
The veteran lefty has struggled this season, coming in with a 7.17 ERA, but he delivered his best start of the year in his last outing against the Astros. Wolf threw six innings, giving up four hits and two earned runs while earning his first win.
The Brewers snapped their six-game road losing streak Sunday in St. Louis and will try to build off that momentum when they head west.
"We were fortunate at home. I thought we put together a couple decent series, but we're still not clicking," manager Ron Roenicke said. "We're still not getting the good pitching that we usually get along with that offense. We'll get it together where everything is going to click right and then we'll be the team that we should be."
Brewers: Gamel nursing sore shoulder
First baseman Mat Gamel got the day off Sunday while trying to fully recover from a sore shoulder he sustained in a home-plate collision Monday vs. the Astros.
Gamel went 0-for-8 against the Cardinals on Friday and Saturday.
"I don't know if the shoulder is bothering [Gamel] other than I know it's still sore," Roenicke said. "I don't know if it affects his swing. He says he's fine, which I'm sure he is. Probably if he would have been swinging great the last couple of days he'd be back in there. It's just my observation that maybe a day would help him."
Padres: Quentin nearing rehab assignment
After undergoing arthroscopic knee surgery on March 19, outfielder Carlos Quentin is closing in on a trip to the Minor Leagues to test out his rehab progress.
"It might be middle of the week," manager Bud Black said. "It's nearing."
Black said Quentin will either play for Triple-A Tucson or Class A Lake Elsinore and will first serve as the designated hitter before playing defense.
Quentin will go through a full day of workouts on Monday when the Padres head back to Petco Park.
"He's still got to run the bases and do more intensive fielding drills," Black said. "Hitting, he feels fine. We're trying to get him up to speed as soon as we can."
Brewers third baseman Aramis Ramirez extended his hitting streak to seven games on Sunday with a game-tying RBI single against the Cardinals in the sixth inning.
In his last 11 at-bats against Wolf, Padres second baseman Orlando Hudson has five hits.
