Zack Greinke pitched one in inning yesterday, facing the top half of the Royals’ regular lineup. Now, beforehand, I thought about the appearance and tempered my expectations. Sure I wanted him to dominate but I thought he’d most likely get through the inning, give up a hit or two, and draw some innocuous feedback like, “The kid, he threw the ball real well. He’s only 20, you know. He still has things he can learn.” Well, the inning went about like I’d hoped. He gave up a hard single to left off the bat of Mike Sweeney and Carlos Beltran reached on a Ken Harvey error. He broke Angel Berroa’s bat in getting him to groundout weakly to second. Then he carved up Juan Gonzalez, getting him to hit a weak comebacker which Greinke himself turned into a 1-6-3 double play. The real story of the appearance, however, is the gradually building buzz surrounding Greinke’s uncanny polish and poise. Joe Posnanski wrote a great piece about it for this morning’s Kansas City Star and captured the Greinke’s growing aura better than I could, as effusive as I feel about the subject right now. He even dropped in some stat analysis and a Baseball Primer reference. It’s only the second week of spring training and the first actual game is today. But clearly Greinke and the Royals’ decision on whether to keep him at the beginning of the season is racing past Jeremy Affeldt’s Blister as the number one spring story.
