"His bat looks like it's made by chasm," Giants manager Bruce Bochy said, referring to Belt's late swings.
However, Belt recorded a couple of deft assists with feeds to pitchers covering first base Sunday. One day earlier, he made several short-hop pickups of infielders' throws, besides alertly starting a 3-5-4 double play after pouncing on Zach McAllister's fourth-inning bunt.
According to fangraphs.com, Belt entered Sunday ranked 10th among Major League first basemen in revised zone rating (which measures the proportion of balls hit into a fielder's zone that were successfully converted into an out) and third in out-of-zone plays made.
Bochy acknowledged Belt's defense by leaving him in the lineup Sunday, due to Cleveland's preponderance of left-handed batters and switch-hitters who would swing left-handed against starter Ryan Vogelsong. Yan Gomes was the only right-handed batter in Cleveland's order.
"We need [Belt's] defense out there," Bochy said. "He has done a really good job with the glove."
