Giants manager Bruce Bochy said Tim Lincecum will be the team's fifth starter. He added Ryan Vogelsong and Yusmeiro Petit will pitch out of the bullpen, but could make an occasional start to give a starting pitcher a break.

Lincecum went 12-9 with a 4.74 ERA in 33 appearances (26 starts) in 2014. He was 2-0 with a 5.73 ERA and one save in seven relief appearances.

Lincecum said he spent the offseason working with his father fine tuning his mechanics. He said he had about 50 throwing sessions with his father this winter.

“I feel more confidence in myself. I feel I deserve the reward you can find from doing the right kind of work," Lincecum said, per the San Francisco Chronicle.
