"Chris has been suspended for violating team rules, for insubordination and for destroying team equipment," White Sox general manager Rick Hahn said in a statement on Sunday. "While we all appreciate Chris' talent and passion, there is a correct way and an incorrect way to express concerns about team rules and organizational expectations."
Sale's suspension began Saturday and runs through Wednesday. The White Sox recalled right-handed pitcher Anthony Ranaudo to take Sale's roster spot during the suspension.
According to ESPN and multiple reports, Sale expressed displeasure over having to wear the White Sox's 1976 navy, collared throwbacks, and the matter escalated from there, leading to a confrontation with a member of Chicago's front office. The team then decided to send Sale home from U.S. Cellular Field.
FanRag Sports first reported that Sale cut up the 1976 throwbacks during batting practice so they couldn't be worn. Fox Sports reported that Sale's dislike for the uniforms was because he thought they were uncomfortable, and that he thought the White Sox were putting "PR and jersey sales" ahead of winning.
The decision to scratch Sale was met with rampant speculation, especially considering that the five-time All-Star has been mentioned in trade rumors in recent days.
The White Sox are reportedly asking for a massive haul in return for Sale -- one source told ESPN that Chicago is seeking five to seven prospects -- with the Boston Red Sox and Texas Rangers rumored to be among those interested.
Sale is 14-3 with a 3.18 ERA this season. He had 274 strikeouts in 2015, the most in the American League.
Information from ESPN's Katie Strang, Jerry Crasnick and Doug Padilla and The Associated Press was used in this report.
