Arizona Fall League Update

Let’s have a look around the Arizona Fall League, a developmental league for prospects that either A) Need a bit of fine-tuning before reaching the Majors, B) Need extra work after missing a chunk of the ’09 season due to injury, and/or C) Are being considered for inclusion on the 40-man roster this winter.

Stephen Strasburg, RHP, Washington
As you’ve probably already heard, Strasburg (The No. 1 overall pick in June’s amateur draft) won his first official pro appearance last week. The right-hander pitched 3.1 scoreless innings and allowed just two hits and one walk. He struck out two batters but, more importantly, he recorded all eight of his in-play outs via the ground ball. A pitcher with a dominating repertoire and a significant ground-ball rate will have a lot of success. ETA: Mid-2010

Chia-Jen Lo, RHP, Houston
The 23-year-old reliever rose to double-A in his first pro season. Lo, a Taiwan native, is leading the AFL in strikeouts with six in four innings of work spread over two outings. He is also inducing a solid number of ground balls. Lo has a fastball that can touch 95 mph, as well as a splitter, slider and changeup. He should be on your watch list and a sleeper candidate for drafting in keeper leagues. He has the potential to be a future closer or set-up man. ETA: Mid-2010

Mike Stanton, OF, Florida
Stanton is swinging a hot bat despite ending the year with modest contact rates in double-A. The outfielder is currently hitting .533 (tied for third in the league) through four games. He has eight hits in 15 at-bats, including a homer. He’s struck out six times and has stolen three bases in as many attempts. If Stanton can improve his base running to the point where he can provide 10-15 steals a season, it will increase his fantasy value. ETA: Mid-2011

Chris Heisey, OF, Cincinnati
Heisey just won’t stop improving. The Cincinnati Reds’ outfield prospect is tied with Stanton in batting average through 15 at-bats. He also has four extra base hits, two walks and a stolen base. Heisey could join fellow youngsters Drew Stubbs and Jay Bruce in the Reds 2010 opening day outfield. ETA: Early 2010

Dustin Ackley, OF, Seattle
The second-overall pick in the ’09 draft, like Strasburg, is making his pro debut in the AFL. Ackley has five hits in 10 at-bats (.500) with one double. He has also stolen a base and has yet to strike out. ETA: Early 2011

Can you draw meaningful conclusions on a pitcher’s GB rate on 3.1 outs? Even Jered Weaver and Justin Verlander have had games this season where they got more groundouts than flyouts, and Halladay and Cliff Lee have had the opposite on occasion.

I also think it’s absolutely absurd to say that GB rate is more important than strikeout rate. I’m not sure if that’s what you meant in the Strasburg bit but that’s what it read like.
