Javier Lopez has a Giant(s) responsibility…

The 39-year-old Puerto Rican former baseball pitcher, who recently retired from the San Francisco Giants, will work as a special instructor for the team at spring training.

Giants general manager Bobby Evans says that Lopez — an important reliever on the Giants’ World Series winners in 2010, ’12 and ’14 — would join the team at its Scottsdale spring home. Pitchers and catchers report Monday with their first workout Tuesday.

“Good for him. We really appreciate what he did here,” manager Bruce Bochy said of Lopez. “When we acquired him in 2010, he helped solidify that bullpen and helped us win that World Series in 2010, getting those big left-handers out for us. As good a player as he is, he’s a better person. Javi’s one of those guys that everybody likes, very much respected and appreciated as a teammate and of course, for me, what he did in the bullpen.”

The four-time World Series champion, who began his career with the Colorado Rockies in 2003, has also played for the Arizona Diamondbacks, Boston Red Sox and Pittsburgh Pirates.
