White Sox closer Bobby Jenks has been fined for throwing behind Rangers second baseman Ian Kinsler during Saturday's 3-2 victory.

ESPNChicago.com has reported the fine, which a source said was worth $750.

Jenks admitted on Monday that he threw behind Kinsler on purpose after a pair of his teammates were drilled with pitches.
