Pat Venditte figures he has an advantage if Major League Baseball and the players' association adopt a three-batter minimum for pitchers starting in 2020: the 33-year-old reliever is a switch-pitcher. The rule, if adopted, might cause less use of left-handed relief specialists. That could benefit Venditte, who has made 56 appearances over three big-league seasons and is at his first spring training with the San Francisco Giants.
