SAN DIEGO -- Matt Wisler, considered the Padres' No. 2 prospect by MLB.com, has a locker in the team's clubhouse.
But Wisler, 21, won't be pitching this month in games for the Padres.
Just as they did in September 2011 with then-rookies Robbie Erlin, Joe Wieland and Casey Kelly, the Padres are giving Wisler an opportunity to acclimate himself to the big league lifestyle and surroundings for a period of 10 or so days.
"I'll get an idea of how they go about their business," Wisler said.
San Diego manager Bud Black said this situation is a little different from three years ago with Erlin, Kelly and Wieland in that the Padres hadn't seen any of those three pitchers before. They have with Wisler -- who logged 11 1/3 innings in big league Spring Training.
This season, Wisler began at Double-A San Antonio before joining Triple-A El Paso, where he went 9-5 with a 5.01 ERA in 22 starts. He found his slider in the second half and pitched better in a league that's known as a hitter-friendly league, going 4-1 with a 4.02 ERA after the All-Star break.
He was 3-1 with a 3.60 ERA in four starts in August.
"I got my command back and my slider felt pretty good," Wisler said.
Wisler will throw a few bullpen sessions in the next 10 days, Black said, under the watchful eyes of the team's pitching coach, Darren Balsley and bullpen coach, Willie Blair. He'll sit in on pitchers meetings, too.
"If his time does come as a Major League pitcher, he'll be better off for this," Black said.
