Chicago White Sox closer Matt Lindstrom is scheduled for left ankle surgery on Friday that will sidelined him for at least three months.

Lindstrom tore the sheath in the ankle on Monday night in the White Sox's 7-6 victory over Kansas City while attempting to field a bunt by Royals shortstop Alcides Escobar during the ninth inning.

"Lindstrom's down for a while," White Sox manager Robin Ventura said. "I don't know if it'll be the rest of the season but it'll be more than 15 days."

The 34-year-old reliever limped off the field Monday and returned to Chicago the next day for further examinations and an MRI, which detected the tear. He was placed on the 15-day disabled list Tuesday.

Lindstrom had six saves and a 3.32 ERA with 11 strikeouts in 19 innings this season. He had converted his last five save opportunities.

Ventura said right-hander Ronald Belisario, who picked up his first save of the season in the 7-6 victory Tuesday over the Kansas City Royals, would close games in Lindstrom's absence.

"I think Beli's pitched well enough to be that guy to step into that spot," Ventura said.
