BOTTOM LINE: The San Diego Padres play the Arizona Diamondbacks on Wednesday. San Diego has gone 28-16 at home and 49-42 overall. Padres hitters are batting a collective .245, which ranks 10th in the NL.

Arizona Diamondbacks starter Merrill Kelly has given up a homer in each of his past four, but has not allowed over four earned runs in any of them.

Whatever calf problem Merrill Kelly was dealing with in the seventh inning here against the Padres on Tuesday, July 8, it wasn't a factor in the one pitch the Diamondbacks right-hander wished he could have back.
