Mets pitching prospect Noah Syndergaard did not take a step toward a major league mound in his second Triple-A start on Wednesday. He yielded three runs on six hits and two walks in five innings, prompting Las Vegas manager Wally Backman to complain about his pace.

"His tempo was way too slow, especially early in the game," Backman told ESPN.com. "He got better as the game went on but there were times he was 20-plus seconds in between pitches. His stuff was there, but everything you hear about in baseball is rhythm and timing and it wasn't there tonight for him."

The 21 year old struggled this spring but could work his way on to the major league roster if he makes progress this season.
