This was a gut-check game for the Rockies. It turns out they had the stomach for it.

They got a pick-me-up performance from Juan Nicasio, who dominated the Atlanta Braves for six scoreless innings in Colorado's 3-1 victory Saturday.

"Juan was great. He battled," said Michael Cuddyer, who put the Rockies on the scoreboard with a solo home run to lead off the second inning. "Whenever he got into trouble, he really bared down and got the outs when we needed them."

Nicasio often teases with his talent, but the stocky right-hander hasn't always delivered on his promise. But he did Saturday, allowing the Braves just two hits. Although Nicasio walked four, he coolly worked his way out of trouble. The prime example came in the third, when the Braves loaded the bases with two walks and a single by B.J. Upton. But Nicasio threw a good, hard slider to Justin Upton, who fouled out to first baseman Justin Morneau.

"I knew that I needed to win today to tie this series 1-1," said Nicasio, who improved to 5-2 and lowered his ERA to 3.61. "It was a big game for us, and I focused on throwing the ball down in the zone."
