Ryan Feltner sharp, Charlie Blackmon homers again

Cubs 5, Rockies 2
Thursday at Salt River Fields

On the mound: Right-hander Ryan Feltner, throwing a sizzling curveball, continues to stake his claim to a spot in the starting rotation. He allowed one earned run on four hits through 5 2/3, walking one and whiffing. Feltner has allowed just two runs over his last 8 2/3 innings (two starts) with nine strikeouts vs. just two walks. … It was not a good day for righty reliever Victor Vodnick, who served up the game-winning, three-run homer to Cole Roederer in the ninth inning. While manager Bud Black likes Vodnick’s stuff, Vodnick’s leaving the ball over the plate too often.
