The Giants first declined their 2008 club option on Walker, then
brought him back. After returning from reconstructive Tommy John
surgery on his throwing elbow and getting called up Aug. 27, Walker
went 2-0 with a 1.26 ERA in 15 relief outings for the Giants. He
didn't allow a run in 14 of those appearances.
"Our bullpen is obviously an area that needs attention, and
bringing Tyler back is a big boost to our efforts," general
manager Brian Sabean said of the San Francisco native. "We all saw
at the end of 2007 that he has returned to form, and we are
confident in his ability to pitch in the late innings come 2008."
The 31-year-old Walker pitched for the Giants in 2004, '05 and
part of 2006, then had a brief stint with Tampa Bay before coming
back to San Francisco.
Also Friday, the Giants hired Roberto Kelly as first-base coach.
Kelly, the organization's former manager of the Class-A Augusta
GreenJackets manager, also will oversee baserunning and outfield
defense on manager Bruce Bochy's staff. Kelly replaces Willie
Upshaw, who was not brought back.
