The Battle of the Rookies

This weekend’s Interleague Series featuring Toronto and Washington may not be a huge draw south of the border, but there are three interesting things to keep an eye on. Firstly, the Nationals were, of course, originally Canada’s first Major League Baseball team – the Montreal Expos. Secondly, it will be the first time that the two clubs have met up since Jays general manager J.P. Ricciardi made some disparaging remarks in the media about (then Cincinnati Reds slugger) Adam Dunn, who now plays in Washington. Do you think Dunn will be locked in?

Thirdly, and most interestingly (as far as I am concerned), this series will feature appearances from five (out of the possible six) rookie starters. Toronto will send veteran Brian Tallet to the mound on Friday, but then he will be followed by rookies Brett Cecil and Ricky Romero. Interestingly, all three pitchers are left-handers. Washington will counter with three rookies this weekend: Jordan Zimmermann, Ross Detwiler (also a southpaw), and Shairon Martis. The Washington line-up is right-handed heavy (with the exception of Dunn and Nick Johnson) so the on-paper match-up goes to the Nationals.

Brett Cecil, 22, pitched fairly well in his first three Major League games this season. It was his fourth start that doomed him and sent him back to the minors. On May 20 in Boston, Cecil allowed 11 hits in 4.2 innings of work, along with two walks and five home runs. Overall, he has allowed 28 hits in 24.2 innings of work, while allowing seven homers and posting rates of 2.19 BB/9 and 6.57 K/9. His ERA is 4.38 but his FIP is 6.39. Cecil also has a ground-ball rate of 52%.

Ricky Romero has been a savior to the Jays’ rotation in 2009, despite missing time with an oblique strain (but what Jays pitcher hasn’t been injured this season). The 24-year-old former No. 1 draft pick has a 3.73 ERA (4.77 FIP) and has allowed 52 hits in 50.2 innings of work. He’s also posted a walk rate of 2.84 BB/9 and a strikeout rate of 7.28 K/9. Romero has a ground-ball rate of 50%.

Jordan Zimmermann, 23, has been inconsistent this season, but his talent is obvious. In 57 innings, he has allowed 61 hits, while posting rates of 2.53 BB/9 and 9.47 K/9. His ERA is 5.37 but his FIP is just 3.79. He has a ground-ball rate of just 44.2%, which has been hurt by a line-drive rate of 25.0%.

Ross Detwiler, 23, has a 5.23 ERA, but once again a Nationals pitcher has a much lower FIP at 3.83. He has allowed 36 hits in 32.2 innings of work. He’s also posted a walk rate of 3.86 BB/9 and a strikeout rate of 6.34 BB/9. Detwiler has done a nice job of keeping the ball in the park with just two homers allowed (0.55 HR/9).

Shairon Martis, 22, has pitched more than any other rookie pitcher in this series at 75 and he’s allowed just 69 hits. His rates, though, are not that good with a walk rate of 4.04 BB/9 and a strikeout rate of 3.45 K/9. His ERA is currently 4.75, with a FIP of 5.14. He’s allowed eight home runs (0.85 BB/9). With a ground-ball rate of just 41.3%, Martis is constantly flirting with disaster thanks to his modest fastball (an average of 90 mph) and his spotty control.

The youth movement in Major League Baseball is in all its glory this weekend in Washington. In fact, the Jays organization actually has more rookies in its Major League rotation right now, than it does in triple-A Las Vegas. So who do you think will win the battle of the rookies – in both this series and in the years to come?
