Koch`s stellar run ends as Crew breaks out
(MLB.com Arizona Diamondbacks)

Right-hander Matt Koch has excelled in place of Taijuan Walker, who is out for the season because of Tommy John surgery. He`s given the D-backs more than they could have expected. But in an 8-2 loss to the Brewers, Koch logged his worst start of the season, as he allowed eight earned runs on nine hits over just 4 1/3 innings.
