Giants’ formidable four help ‘pen winning script

Sergio Romo and playoff newcomers Jean Machi and Hunter Strickland each surrendered home runs in relief on Sunday. On Tuesday, manager Bruce Bochy stuck with Romo, but he first turned to his more experienced relief arms. As usual, they didn’t disappoint in Tuesday’s 5-4 walk-off win over the Cardinals in Game 3 of the NL Championship Series.
