ATLANTA — Command problems led to an early night for Paul Clemens just when he thought he was ready to show he could pitch deeper into games.

Clemens was pulled without recording an out in the fourth inning and the San Diego Padres fell to Matt Wisler and the Atlanta Braves 8-1 on Wednesday night.

Clemens (2-4) was hurt by four walks as he allowed two runs, one earned, in three-plus innings. He left with no outs and the bases loaded in the fourth.

“I think probably the most frustrating thing was how good I felt, you know, like I’m finally turning a corner, ready to work deep into a ball game,” Clemens said. “It kind of fell apart and got away from me there in the fourth inning. It’s going to be a tough one to swallow for the next couple days.”

Padres manager Andy Green said Clemens “labored.”

“He honestly looked like he was tired a couple of innings into the game,” Green said.

When told of Green’s assessment, Clemens said “Yeah, I think labored is the right word to use.”

Oswaldo Arcia’s fourth-inning homer gave the Padres their only run.

Clemens has allowed no more than three earned runs in six of seven starts. Strong relief pitching from Jose Dominguez helped lessen the damage against the Braves. Dominguez struck out Dansby Swanson and Wisler hit into a double play to end the fourth.

Clemens, signed by Atlanta in the 2008 draft, made his first career appearance against the Braves.

Wisler (6-11) set a career high with 10 strikeouts while allowing only four hits and one run in six innings.

Wisler is 2-0 with a 1.29 ERA in two starts since returning from one month spent at Triple-A Gwinnett.

“I think it was in my best interests to go down,” Wisler said. “… I got to just clear my head and go down and make some adjustments without really worrying about it too much.”

The Braves led only 2-1 before Gordon Beckham’s two-run double off Kevin Quackenbush in the sixth. Ender Inciarte added a two-run single in the four-run inning.

MINOR EXPANSIONS

The Braves and Padres plan to make only a small number of moves on Thursday when rosters can be expanded.

Braves interim manager Brian Snitker said catcher A.J. Pierzynski (left hamstring strain) and RHP Chris Withrow (right elbow inflammation) are expected to come off the disabled list.

The Padres plan to recall left-hander Ryan Buchter. Infielder Alexi Amarista (left hamstring strain) is expected to join the team Friday in Los Angeles. The team recalled catcher Hector Sanchez from Triple-A El Paso on Wednesday.

TRAINER’S ROOM

Padres catcher Christian Bethancourt was placed on the 15-day DL after he suffered a left intercostal strain on a swing in Tuesday night’s game. “I didn’t know It was that painful,” he said of the injury. … RHP Tyson Ross, on the DL with right shoulder inflammation, felt discomfort following his first rehab start last week. Green said it was “not a major setback.”

UP NEXT

Padres: RHP Jarred Cosart will make his sixth start with Padres, and 10th overall of the season. Cosart was traded to San Diego from the Marlins on July 29.

Braves: RHP Mike Foltynewicz, coming off a win over the Giants, will make his second career start against San Diego and first of the season.
