SAN DIEGO — The Giants still have the best record in baseball, but their bullpen has stumbled more often than any other.
Their failure was literal Saturday night. Santiago Casilla failed to retire a batter or protect a one-run lead in the 10th inning and balked in the winning run when he tripped while attempting to deliver a pitch as the Giants lost 7-6 to the San Diego Padres at Petco Park.The Giants have 18 blown saves, more than any other team. And this might be the game that leads to a closer change.Casilla took the mound after Buster Posey had sent up a rescue flare with his home run in the top of the 10th inning — the first of his career in extra innings.
