Rockies prospects: Jon Gray loses perfect game in 6th inning of 1-0 loss

Double-A Tulsa: L 1-0

Jon Gray was perfect through 5⅔ innings on Wednesday before surrendering three consecutive singles, one of which resulted in the only run of the game scored by either team. Despite falling short of his bid for history, Gray was still excellent, striking out eight batters in six innings while allowing only three hits and walking none. His difficult start to the 2014 season now seems like a distant memory after two straight tremendous starts. Gray now has 19 strikeouts against only three walks in 18⅓ innings.

High-A Modesto: L 7-0

Matt Wessinger went 4-for-4 and Sean Dwyer had a couple of hits, including a double, but the Nuts were unable to make any of their eight hits as a team count. Trevor Story singled and walked in four plate appearances while Will Swanner went 0-for-2 with two free passes.

Starter Matt Flemer wasn't awful in five innings, surrendering only two runs on six hits and two walks, but Shane Broyles came on in relief and proceeded to allow five runs on five hits in two frames.

Low-A Asheville: L 6-0

Ryan McMahon shockingly did not hit a home run and actually failed to get any sort of hit, going 0-for-3 with a walk. Pat Valaika had a pair of hits including a double and David Dahl also doubled and stole a base, but the Tourists went 0-for-6 with runners in scoring position.

Zach Jemiola gave up three runs on six hits and a walk in five innings. The 20-year-old right-hander has allowed 31 hits in 19⅔ innings and has only 10 strikeouts this season. Trent Daniel turned in a positive outing out of the bullpen, striking out two in a flawless eighth inning.

Triple-A Colorado Springs: Off

The Sky Sox are back in action tonight against the Iowa Cubs and have a familiar face on the mound as Jhoulys Chacin makes what should be his final rehab start before returning to the Rockies' rotation.
