Early this season, batters loved facing Derek Law, whose slider and curve were roughly the same speed and broke roughly the same way.
“They could sit on basically the same pitch,” Law said Friday after rejoining the Giants as part of the first wave of September call-ups.
After Law posted a 2.13 ERA as a rookie, the Giants expected him to be the primary setup man, but they had enough of his 5.40 ERA through mid-June and optioned him to Triple-A Sacramento.
Out the door, he heard from Buster Posey, who suggested he work on differentiating his pitches.
