April 12--ST. LOUIS -- The need for pitching insurance resulted in the Chicago Cubs recalling left-hander Chris Rusin from Triple-A Iowa on Saturday.
Rusin will serve as a long reliever with Carlos Villanueva starting Saturday's game at St. Louis.
Reliever Brian Schlitter was optioned to Iowa.
Rusin, 27, was 0-2 with a 6.52 ERA in two starts for Iowa. He allowed just two earned runs in 6.0 innings in his last start against Nashville.
