"This is how we've done it," Bochy said. "Sanchez has done a great job catching and gotten some big hits. After contemplating it for a while I decided to go with it."Sanchez, who didn't appear in the series' first three games, hit .280 in 74 regular-season games. Meanwhile, Belt has been gripped by the offensive malaise that has stricken most of the Giants, who entered Wednesday batting .126 (12-for-95) in the series. Belt was 1-for-9 overall, including 0-for-4 with three strikeouts in Tuesday's Game 3. Bochy excused Belt by citing the excellence of Cincinnati's pitching. "But I will say that maybe Sanchez can help the offense a little bit," Bochy added. Posey, the National League's batting champion with a .336 average, hit .378 with a 1.093 OPS in his 29 games at first base.
