Two-time NL Cy Young Award winner Tim Lincecum will pitch for major league clubs in a showcase event Friday as he attempts to make a comeback from hip surgery last year.

The free agent right-hander is set to hold his much-anticipated throwing session Friday in Arizona, according to Paul Kuo, spokesman for Lincecum's agency, Beverly Hills Sports Council.

The Giants will be there as planned all along, general manager Bobby Evans said Sunday. The Padres and Orioles also are among the expected 20 or so attendees, according to MLB Network.
