SAN FRANCISCO -- Buster Posey's increased efficiency at throwing out basestealers is one noticeable early-season trend that has helped the Giants.
Posey entered Thursday having thrown out 40 percent of opposing thieves (six of 15). Last year, he caught 26 percent (31 of 118).
Posey devoted part of his offseason to improving his explosiveness in springing from his catcher's crouch, which has enhanced his throwing ability. Manager Bruce Bochy noted that Giants pitchers have been more vigilant at holding runners on base, too.
"Last year, that was not a strength of ours," Bochy said.
