PITTSBURGH -- Right-hander Craig Hansen, struggling with his control since being traded to Pittsburgh last month, was optioned to Triple-A Indianapolis on Wednesday.
The Pirates picked up the contract of right-hander Jesse Chavez from their top farm club.
Hansen, obtained from Boston in the three-team trade that sent outfielder Jason Bay to the Red Sox on July 31, was 0-2 with a 8.10 ERA in nine games with Pittsburgh.
On Tuesday night, he walked in the tying and go-ahead runs during the Cubs' seven-run, eighth-inning rally. Chicago won 14-9.
The 25-year-old Chavez was 2-6 with 14 saves and a 3.80 ERA in 51 relief appearances at Indianapolis. The Pirates acquired him in the 2006 trade that sent right-handed starter Kip Wells to Texas.
To make room for Chavez on their 40-man roster, the Pirates transferred left-hander Phil Dumatrait (left shoulder surgery) from the 15-day to the 60-day disabled list.
