CHICAGO -- After a 14-nning game that put a major strain on the bullpen, the Chicago White Sox purchased the contract of right-hander Zach Putnam from Triple-A Charlotte on Thursday and designated left-hander Donnie Veal for assignment.
Putnam, 26, has 15 games of major league experience, most recently the five games he pitched in relief for the Chicago Cubs last season. In six relief innings at Charlotte this season he had 11 strikeouts.
Veal made seven relief appearances for the White Sox this season, posting a 7.50 ERA. He walked seven batters in just six innings.
The White Sox will need to pick up innings for right-hander Daniel Webb, who could be down for as many as two games after throwing 59 pitches over three innings in Wednesday's defeat to the Boston Red Sox.
