Tucson, Ariz. ? Zack Greinke was far more pleased with his first start than with the three innings he threw for the Kansas City Royals on Wednesday against the Colorado Rockies.

Nonetheless, he extended his scoreless streak this spring to six consecutive innings, allowing two hits in that stretch.

Greinke, the reigning American League Cy Young Award winner, threw 51 pitches — 31 for strikes — to help the Royals to a 5-0 victory Wednesday. He gave up a first-pitch double to Troy Tulowitkzi with two out in the first and allowed two runners to reach base in the third on an error and a walk.

“It still wasn’t as sharp as the game before,” said Greinke, referring to the 27 pitches he threw in three innings Friday against Texas. “It was a little chilly out and it just was hard to get loose. So everything wasn’t as crisp.”

Greinke is on schedule for his Opening Day start April 5 against the Detroit Tigers.
