Flushing, NY (Sports Network) - The Chicago Cubs have suspended infielder Ian Stewart 10 games for his tweets regarding manager Dale Sveum.
Stewart was sent to Triple-A Iowa in early May and was vocal on Twitter about him demotion earlier this week.
"I think Dale doesn't like me and he's running the show," he tweeted. "...there [sic] going to let me rott [sic] in AAA all season and then non tender me after."
Theo Epstein, the president of baseball operations for the Cubs, announced the suspension on Friday.
"His loyalty clause in his contract requires certain standards of personal conduct, and he didn't adhere to that," Epstein said. "He made a mistake, he apologized for it and we're taking some disciplinary action. It's over at that point."
The 28-year-old Stewart signed a one-year deal with the Cubs last offseason but has not seen action with the big club this year. He is hitting .168 with five home runs and 20 RBI in 40 games with Iowa.
Stewart owns a career .232 average with 59 homers and 204 RBI in 487 career major league contests.
