Edinson Volquez lasted just 4 1/3 innings in a no-decision against the Rockies on Sunday, allowing four runs -- two earned -- on six hits. More than the hits allowed, Volquez was done in by the four walks issued. It was Volquez' second straight subpar start after a four-game run of strong performances. It's been that kind of year for the right-hander, who is 8-7 with a 3.87 ERA and 1.30 WHIP through 121 innings of work. He's got a chance to get back on the horse against a bad Diamondbacks club on Friday.
