One of the great subplots of every Major League season is the rookies that come up and show a glimpse of baseball’s future. It’s what had us enthralled by Jackie Bradley Jr. all spring, what has us dutifully analyzing Julio Teheran appearances, and what has us so eagerly waiting for Jurickson Profar and Wil Myers. This season, we will track rookies, both the prospects and suspects, as they make adjustments to playing in the bigs. This bi-weekly list will highlight rookies who have accomplished the most in 2013, regardless of future projection (though that will always be discussed). These are the players whose week one performances deserve recognition.
1. Dan Straily, RH SP, Athletics
If we’ve learned anything from Yu Darvish this season, it’s that success pitching against the Astros is not exactly analogous to pitching against baseball’s other 29 teams. The Athletics know this, why is probably why just one day after an 11 strikeout, 0 walk performance (a start worth an unofficial 0.6 WAR by our metrics), the A’s were comfortable sending Straily back to Triple-A. As sixth starters go, Straily is an excellent one, with a fastball at 90-93 mph, 83-86 mph slider, and 82-85 mph change (let’s agree to ignore that low 70s curveball, please). He showed great command against the Astros, the best he’s had in all 8 starts at the Major League level.
But, I don’t want to get too wrapped up in Straily’s success. The Astros, as we’re finding out, are a historically swing-and-miss team. All 11 of Straily’s strikeouts were of the swinging variety, and amazingly, nine were against left-handed hitters. Brett Wallace and Rick Ankiel struck out a combined 6 times, all on Straily fastballs. While Baseball America’s scouting report of him, as the A’s #6 prospect, reads “[His] slider and change up are his two best offerings and account for the bulk of his strikeouts,” that wasn’t true against Houston. Eight of the 11 strikeouts were from the fastball, and a remarkable number of them looked like this to Jason Castro — right down the heart of the plate. If you want to see why we simply can’t get too excited about Straily yet, consider the caliber of competition:
