KANSAS CITY -- Left-handed pitcher Danny Duffy underwent successful Tommy John surgery by Dr. Lewis Yocum on Wednesday in Los Angeles, according to the Royals.

"Dr. Yocum was very pleased with it," said team spokesman Mike Swanson.

Swanson said that Duffy was already getting antsy and was filling his time by Tweeting and texting teammates -- with his right hand, of course.

His surgery was delayed by strep throat. Duffy has been out since May 14, finishing his season with a 2-2 record and 3.90 ERA in six starts. Normal recovery time for the elbow reconstruction procedure is 10 to 14 months.

Second-round pick Selman signs deal

KANSAS CITY -- Second-round Draft choice Sam Selman, a left-handed pitcher from Vanderbilt University, has signed with the Royals, the club announced on Thursday.

Selman, 21, had a 9-3 record and a 3.55 ERA in 17 games this year as a junior for the Commodores. The 6-3, 185-pound Selman is a product of St. Andrews High in Austin, Texas.

He was the 66th player taken overall in the First-Year Player Draft. Terms were not announced but he was believed to have signed for less than the $781,600 slotting figure.

The Royals have signed all of their first 11 selections and 28 of their 40 picks.

Yost nearly had to use Chen in outfield

KANSAS CITY -- The Royals were out of position players as Wednesday night's game against the Brewers went into extra innings.

By the 11th inning, manager Ned Yost was down to his starting pitchers plus relievers Jonathan Broxton and Nate Adcock.

"Now I'm thinking if somebody gets hurt, what am I going to do? I was going to have to put a pitcher in the outfield," Yost said. "The best thing I could come up with is I walked up and told Bruce Chen to put his spikes on. He said, 'You want me to go to the 'pen?' I said, 'No, Bruce, get your glove. If something happens, you're going to go to the outfield.' He ran up and put his spikes on but, thank God, we didn't have to do that."

The Royals won, 4-3, in the 11th to avoid that possibility.

Pop artist presents piece for All-Star Game

KANSAS CITY -- Pop artist Charles Fazzino was on hand at Kauffman Stadium ahead of Thursday night's game against the Brewers to present a piece of commemorative artwork for the 2012 All-Star Game.

Fazzino was accompanied by Royals legend George Brett, this summer's All-Star ambassador, to unveil the artwork during a special ceremony behind home plate. Brett and Fazzino also held a poster signing in the team store, with a portion of the proceeds benefiting Royals charities.

Fazzino wasn't the only artist participating in the pregame ceremonies. Rock and Roll Hall of Famer Alice Cooper threw out the first pitch. Cooper is in town for a concert Friday night.
