CHICAGO -- The Cubs on Tuesday recalled Jake Fox from Triple-A Iowa and placed left-handed pitcher Jason Waddell on the 15-day disabled list, retroactive to June 13, for evaluation and treatment of a non-baseball related medical issue.
With the move, the Cubs now have 12 pitchers on the 25-man roster.
"If we need more than 12, we've really got problems," Cubs manager Lou Piniella said.
This is Fox's second stint with the Cubs, having gone 5-for-12 with two doubles and two RBIs in eight games from May 27-June 9. He was 5-for-6 with two doubles and an RBI as a pinch-hitter.
Fox was batting .409 with 44 runs, 14 doubles, three triples, 17 homers and 53 RBIs in 45 games for Iowa. He leads the Minor Leagues in batting average, on-base percentage (.495) and slugging percentage (.841).
Since he was optioned to Iowa on June 9, Fox has reached base safely in three of four games, going 3-for-13 with three runs, a triple, two RBIs and four walks.
