Some quick notes from the Colorado Rockies' Class A scrimmage yesterday.
• I'll start with the player about whom I have the least to say: 2012 first-rounder David Dahl (my No. 37 prospect in MLB). He had just two at-bats, and I observed one swing from the open side, and he was a little out in front of the ball but showed good bat control and nice balance. I'd like to see him again for a full game before he heads out to low-A next month.
• Center fielder Max White, who replaced Dahl in the game, was the pleasant surprise of the day. White, the team's second-round pick (third overall) in the 2012 draft, showed a simple, clean swing, making some hard contact while showing average to slightly better running speed. He did get turned around on one deep fly ball over his head, the only difficult play he had in the field.
• Shortstop Rosell Herrera has good bat speed and a loose, middle infielder's body, although his leg kick is late enough that he was running into timing problems, sometimes not getting his foot down until after he'd already started his swing. He's an average runner but his feet worked fine at shortstop and he has plenty of arm. Herrera was awful at the plate in low-A Asheville last year, hitting .202/.271/.272 as a 19-year-old in a good hitters' park, but was somewhat more successful after a demotion to advanced short-season ball.
This is a pretty significant year for him, as he has the tools to be an everyday shortstop if he can hit, and a second time through the Sally League, this year at age 20, has to yield better results.
• Raul Fernandez finished off the game, sitting 93 mph to 96 mph, flashing a slider at 83, and throwing something else -- a bad changeup or a two-seamer -- at 89-81 mph, all from a slot a little under three-quarters. He's pitched two years in short-season ball with low walk rates, but obviously could use a stronger second pitch. That's impressive arm strength, though, and it's a little surprising he passed through the Triple-A phase of the Rule 5 draft unclaimed.
• Carlos Yan also threw in the game, working from 90-94 mph with some feel for a changeup at 80-81 mph, but no breaking ball. He's a 22-year-old righty from the Dominican Republic who hasn't pitched in the U.S. yet, but at 6-foot-5 with some room to fill out, he's an interesting arm-strength candidate, a little more so than his age would indicate, because he signed only 19 months ago.
