The aftermath of a late-night athlete Twitter rant is never pretty.
Exhibit A: Demoted Chicago Cubs third baseman Ian Stewart.
Cubs general manager Theo Epstein told reporters Tuesday the club has suspended the 28-year-old without pay for a string of tweets that broke the loyalty clause in his contract.
"The cubs are done with me," Stewart wrote. "They're going to let me rot in AAA all season and then non tender me after.
"They might as well release (me) since I have no shot of a call-up."
His parent club wasn't amused.
"We spent the entire morning dealing with an issue that doesn't help us get better as an organization," Cubs general manager Jed Hoyer told the Chicago Tribune. "That's not how we want to spend our time."
Stewart was playing for the club's triple-A affiliate, the Iowa Cubs.
The length of the suspension is till unknown.
Stewart struggled mightily the past two seasons with the Cubs, hitting .164 in 39 games in 2013 after batting .201 in 55 games in 2012.
Stewart is obviously not happy about his present situation.
An avid tweeter -- he goes by the handle "BeefStew2" -- Stewart complained to fans for a couple of hours, starting around midnight.
Roy Oswalt is a start away from rejoining the Colorado Rockies' rotation.
The Denver Post reported Tuesday that Oswalt, 35, will make one more minor league start, possibly Friday, at double-A Tulsa before he's promoted to the big league club.
After agreeing to a minor-league deal with Colorado in early May, Oswalt has put up an impressive 2.88 ERA over 25 innings, striking out 18 batters along the way.
The three-time all-star's fastball is reportedly topping out in the low 90s.
In 17 appearances last season with the Texas Rangers, Oswalt finished 4-3 with a rather unimpressive 5.80 ERA, the worst in his 12-year MLB career.
Washington Nationals outfielder Bryce Harper underwent "no operative procedures" during his visit with orthopedist James Andrews Monday, according to the Washington Post.
Speculation arose after a photo of Harper wearing a knee brace surfaced on Twitter. But his agent, Scott Boras, said the brace was just a precautionary measure "to keep (the) knee immobile," and specified that arthroscopic surgery was not performed.
Harper was diagnosed with bursitis in his left knee after crashing into the Dodger Stadium fencing on May 13. He continued to play until May 26 and was placed on the disabled list June 2.
