MLB roundup: Giants cap rally from 8-run deficit with walk-off slam

The San Francisco Giants staged a dramatic rally from an eight-run deficit to beat the Washington Nationals 11-10 at Oracle Park on Wednesday. Bryce Eldridge, 21, delivered a walk-off grand slam with no outs in the bottom of the ninth, capping a 10-run surge over the final two innings. He became the youngest player in major league history to hit a walk-off grand slam, 109 days younger than Roberto Clemente's 1956 mark. Foster Griffin carried a four-hit shutout into the sixth before Chapman homered; he allowed one run on six hits over six innings. Reiver Sanmartin (1-0) earned the win in his Giants debut after two innings of one-run relief.
