PHOENIX (AP) - The way things are going for Vidal Nuno, he could pitch a no-hitter and not win.

The left-hander had his best start since coming to Arizona, allowing a run on two hits and retiring the last 20 he faced before leaving after eight innings.

But still he got the loss in the Colorado Rockies’ 2-0 victory on Saturday night.

“I don’t know what more he can do,” Diamondbacks manager Kirk Gibson said. “He gave up a home run and retired 20 in a row. He didn’t walk anybody. He struck out seven guys. It is a shame.”

Nuno (2-9) is 0-4 in 10 starts since he came to Arizona in the trade that sent Brandon McCarthy to the New York Yankees. In seven of those starts, he has allowed two runs or fewer.

“There’s no frustration,” he said. “You got to love this game and just go out there and try your best.”

The Diamondbacks are 1-9 in games Nuno has started.

“He has been good the whole time he has been here,” Gibson said. “If you go look at this starts since he has been here, not many guys have thrown the ball that good. We have not scored for him.”

Nuno allowed his only run on Matt McBride’s second-inning homer, then didn’t allow a runner to reach base again.

But Colorado rookie Tyler Matzek shut out the Diamondbacks in his seven innings.

The 23-year-old left-hander gave up three hits in seven innings.

Maztek (4-9) struck out four and walked three. The win came on the heels of a strong seven innings in a 3-2 victory over San Francisco on Monday.

“He’s been close to dominant the last couple of times out,” Rockies manager Walt Weiss said. “It’s good to see. It’s good to see a kid developing as we speak. He’s getting better and better. It’s real encouraging what we see from Tyler.”

The Rockies had lost four in a row since then.

Charlie Blackmon homered off reliever Matt Stites in the ninth.
