Though Giants first baseman Brandon Belt has been hitting the ball well on his minor-league rehab assignment, his thumb is still sore, according to MLB.com.
Manager Bruce Bochy said the team could have accelerated his timeline based on Belt's .588 average in his first five rehab games, the soreness has made them aim for more caution. Belt has not played since May 9 when he suffered the injury, but he is on schedule to return Friday against the Padres.
