The Arizona Diamondbacks face the San Diego Padres in the third game of a 4-game set at Petco Park in San Diego Wednesday.

Diamondbacks starter Merrill Kelly has given up a home run in each of his past four, but has not allowed more than 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.
