Buster Posey

Buster Posey not in Giants' lineup Wednesday

San Francisco Giants catcher Buster Posey is not in the Giants' lineup Wednesday against the Arizona Diamondbacks.

What It Means:

It's a day off for the catcher, who has already played in 130 games for the fourth straight season. Jackson Williams will get the start behind the dish with Posey out.

Posey is having another superb season. He owns a .373 wOBA and has blasted 17 homers to go with 82 RBI. His 36 percent hard-hit rate is the highest mark of his career. At 28 years old and counting this year, Posey has already amassed five four-win seasons, according to Fangraphs Wins Above Replacement.
