The Atlanta Braves suspended struggling second baseman Dan Uggla for one game Sunday.
The team announced the suspension on Twitter but did not explain why Uggla is being disciplined.
Manager Fredi Gonzalez would not elaborate before the Braves' game against the Chicago Cubs.
"I'm not going to say anything other than that it's an internal matter," he said. "That's the way I like to handle stuff, and the Atlanta Braves like to handle stuff. And that's it. You can ask me 400 different ways and my way is that we're going to handle it internally."
Uggla, 34, has played sparingly since rookie Tommy La Stella was promoted from Triple-A Gwinnett on May 28. Uggla is batting just .162 with two home runs and 10 RBIs in 48 games.
Gonzalez said he expects Uggla to be with the team when it returns from the All-Star break Friday against the Philadelphia Phillies. He does not expect the suspension to affect the club.
"I don't think so. I got a pretty good pulse of our clubhouse," he said. "If anybody wants to talk to me, my door is always open. And they know that."
Atlanta recalled infielder Phil Gosselin from Triple-A Gwinnett on Sunday. Gosselin batted .345 with five home runs and 30 RBIs in 88 games with Gwinnett.
"He's had a terrific first half of the Triple-A season," Gonzalez said.
Uggla, a three-time All-Star, is in the fourth year of a five-year, $62 million contract. He is due $13 million in 2015, the final year of the deal.
$1M FOR RUTH CONTRACT
Babe Ruth's $5,000 contract with the Boston Red Sox in 1918 sold at an auction Saturday night for $1.02 million.
The contract included signatures by Ruth, American League president Ban Johnson and Red Sox owner Harry Frazee.
The winning bid represents the highest ever paid for a sports contract. The previous record was for the document that sent Ruth to the New York Yankees in December 1919, which sold for $996,000 in 2005.
Goldin Auctions of New Jersey told ESPN.com that the buyer of the Ruth contract requested to remain anonymous.
The auction, at the Sports Legends Museum in Baltimore, coincided with the 100th anniversary of Ruth's major league debut.
Other Ruth items that sold at the auction included: a bat from early in his career for $215,000 and a signed ball for $96,000. One item that did not sell was the first home run ball that Ruth hit at Yankee Stadium because it failed to get the required $100,000 reserve.
YANKS RECALL MITCHELL
The New York Yankees made a series of moves on Sunday.
The club recalled right-handed pitcher Bryan Mitchell from Triple-A Scranton/Wilkes-Barre, optioned outfielder Zoilo Almonte and right-hander Matt Daley and outrighted right-hander Jim Miller to Scranton/Wilkes-Barre.
Mitchell 1-0 with a 0.00 ERA in three innings with the Yankees this season. Almonte is batting .160 in 25 at bats. Daley is 0-0 with a 4.85 ERA in 12 relief appearances. Miller has allowed six runs (all earned) in 2 2/3 innings.
