The St. Louis Cardinals have fortified their bullpen, recalling rookie right-hander Blake Hawksworth from Triple-A Memphis and demoting Jess Todd to their top farm club.

The 26-year-old Hawksworth was a starter in Memphis but will serve as a long reliever with the Cardinals. He was 5-4 with a 3.92 ERA for the Redbirds before Saturday's promotion.

St. Louis could need Hawksworth to absorb some innings in the next couple days. Joel Pineiro is scheduled to pitch Sunday after missing his last start due to back spasms. Brad Thompson is slated for his second straight fill-in start Monday, this time for injured Kyle Lohse.

Todd allowed two runs in 1 2-3 innings Friday night and threw 45 pitches, making him unavailable for a few days.
