I'm out in Arizona this week for four days of Arizona Fall League scouting, catching two games each day before I head home on Saturday. Here's the first set of notes on players I've seen so far, with more emphasis on pitchers who've stood out through four games.

• Minnesota right-hander Alex Meyer, acquired in the Denard Span trade, started the first game on Tuesday, hitting 100 mph in his first inning and sitting 96-99 for three innings with great sink on the pitch. Although he's 6-foot-9, Meyer comes from a low 3/4 arm slot, which puts that action on the ball but increases the need for him to develop his still-fringy changeup, which he barely threw on Tuesday. His slider was hard at 84-87, a swing-and-miss offering that he doesn't yet throw for enough strikes. Much of what Meyer needs to accomplish comes down to his size -- tall pitchers often have trouble repeating their deliveries and maintaining their coordination, which hurts command. If Meyer can get that consistency with his delivery, he's a potential top 30 starter because he can miss bats and get ground balls, but he will have to throw more and better strikes first.
