Helton began the season 2-for-21 with two singles and two RBIs in his first six games but had since gone 9-for-20 before his stretch on the disabled list, which tested the patience of his teammates and Weiss' coaching staff.
"He has been driving us crazy," Weiss said. "At some point about halfway through his DL stint here in the dugout, I tried to get [head trainer Keith Dugger] to hit him with a tranquilizing dart. But it's good to have him back out there. It'll be nice watching him take [at-bats] again, doing his thing."
The Rockies acquired Wheeler in the offseason from the D-backs for left-handed reliever Matt Reynolds. Wheeler began the season at Colorado Springs, and in six games with the Rockies, including one start, went 1-for-9 (.111) with a double.
