The move accomplishes three objectives.
First, it gives Collmenter some extra rest. The right-hander has thrown 153 1/3 innings so far this year, the most in his professional career.
Second, because Thursday was an off-day, Kennedy will be pitching on regular rest rather than getting an extra day.
And finally, in case the D-backs were to drop their final six games and the Giants won their final six, the two teams would meet in a one-game playoff next Thursday and Kennedy would be set to go on regular rest for that contest.
"Not planning on it," Gibson said of the one-game playoff scenario. "We just have to be prepared, not for the worst, just be prepared."
