Padres call up lefty prospect Erlin, option Weber

SAN DIEGO -- To be clear, Padres manager Bud Black never likes calling a player into his office to tell him he's on his way back to the Minor Leagues.

It was different with pitcher Thad Weber, who was sent back to Triple-A Tucson on Wednesday after he tossed 4 2/3 scoreless innings of relief, saving the bullpen in a 6-3 loss to the Brewers on Tuesday.

"He's got a good perspective on it," Black said. "He understands why he was here in the first place, and why he was sent back."

Needing a fresh reliever for the series finale against the Brewers on Wednesday, the Padres selected left-hander Robbie Erlin from Tucson. Erlin was in uniform before Wednesday's game.

"I'm excited to be here," Erlin said.

Erlin, 22, and right-handed pitcher Joe Wieland were obtained from the Rangers at the 2011 Trade Deadline for reliever Mike Adams.

Erlin was 2-0 with a 4.73 ERA in three starts for Tucson. He pitched five innings in his last start on April 19. He walked seven in 13 1/3 innings with 10 strikeouts and 18 hits allowed. He hasn't allowed more than two earned runs in each of his last two starts.

Erlin said he's done a better job of pitching inside to right-handed batters, which can be a tricky issue for a left-handed pitcher who doesn't rely on plus-velocity.

"You just try to be aggressive with it," Erlin said. "You can't be tentative. You've got to trust it."

If and when Erlin makes an appearance, he'll be the 14th pitcher used by the Padres this season.
