Prior to the game, Belt made a promise. Via San Jose Mercury News:
Belt made his promise just before game time, after watching Lyndsey throw out the ceremonial first pitch. The girl had chosen to wear a Belt T-shirt for the occasion, so as she trotted off the mound, Belt raced out of the dugout to say hello.
Belt, on a rehab assignment from a broken thumb, felt an instant kinship with the girl on the mend. Lyndsey has undergone 31 bouts of radiation and nine rounds of chemotherapy. At the end of the conversation, Belt told her: "I'm going to hit a home run for you."
It didn't take Belt long to make good on his promise, either, because in the first inning, he homered:
After the game, Lyndsey received a ball, signed "to Lyndsey, my good luck charm. Brandon Belt."
Well done, Brandon.
