1. Brett Anderson, LHP, Oakland
Anderson holds the narrow edge over Romero is K/9 with 7.25, good for 18th in the league for pitchers with more than 90 innings pitched. Anderson has the 12th lowest FIP in the AL at 3.91, six spots ahead of Bergesen. The southpaw also has the second lowest line-drive rate in the AL, four spots head of Porcello.
3. Brad Bergesen, RHP, Baltimore
Bergesen is 12th in the league in BB/9 (90 IP+), five spots ahead of Anderson. He’s also 12th in the league in HR/9 at 0.80, five spots ahead of Niemann.
4. Gordon Beckham, 3B, Chicago
Beckham leads rookies in batting average (200 PA minimum) but is just 35th in the league. He also has the highest BABIP for rookies at .331, 26th in the league. Defensively, UZR doesn’t like Beckham, but he has shown good range.
5. Andrew Bailey, RHP, Oakland
Bailey is seventh in the AL in saves with 17 (40 IP+). He’s also eighth amongst all AL relievers in K/9 with a rate of 10.13. The right-hander is helped by a low .249 BABIP.
Watch Out For:
Matt Wieters, C, Baltimore
He had a slow start to his MLB career, but this promising catcher is really playing well now… It remains to be seen, though, if he can catch up to all of the rookies above.
Nolan Reimold, LF, Baltimore
Reimold is tops in BB% at 11.5%, but that is good for just 34th in the league. No rookie is amongst the top 35 hitters in OPS, ISO or wOBA. Defensively, he’s one of the worst left fielders in the AL.
Ricky Romero, LHP, Toronto
Romero is often the second or third best rookie pitcher in any one of the categories, including K/9 and GB%.
Rick Porcello, RHP, Detroit
Porcello has the highest ground-ball rate in the American League at 56%, two spots ahead of Romero, five spots ahead of Bergesen and seven spots ahead of Anderson.
Jeff Niemann, RHP, Tampa Bay
Niemann has the 14th lowest batting-average-allowed in the league, four spots ahead of Romero.
