SF Giants’ Sanmartin to miss WBC due to injury, Peguero reinjures left hamstring

SCOTTSDALE, Arizona — Injuries continue to throw a wrench into the Giants’ wide-open bullpen competition — and are robbing one player of an opportunity to participate in the World Baseball Classic.

Left-hander Reiver Sanmartin was slated to pitch for Team Colombia in this year’s WBC, but the 29-year-old sustained a right hip flexor injury in Colombia’s exhibition against the Pittsburgh Pirates on Tuesday in Florida while fielding a comebacker that will keep him out of the tournament.
