It's Spring Training. You know better.
No? You don't know better? You're out buying Maya jerseys as I type? Let's do the drill then.
Last year - who was 2nd in batting average for Spring Training for the Nats? That's right Alberto Gonzalez. 4th? Willie Harris. 5th? Desmond. 6th? Pudge. Most RBIs? Desmond. How did Adam Dunn do? .208 average, and NO homers.
Who had the best ERA? Aaron Thompson. With 10+ innings? John Lannan. Brian Bruney had a 3.60 ERA. Matt Capps had a 7.71 ERA.
We can do this for other years if it'll make you feel better. How a guy looks in Spring Training has almost no correlation to how he'll do that year.
As for Maya - may I also bring in another bit of context. It's often brought up how he pitched much better in the Winter Dominican League (1.32 ERA!) and earned their pitcher of the year award. Who led the Winter Dominican league in hitting? Hector Luna. A 31 year old AAA player who batted .138 in limited at-bats with the Marlins last year and who hasn't been startable since 2006. Homers? Brad Nelson. A 27 year old with 2 total major league extra base hits, rated the #23 prospect in America... in 2003, now entering his 5th season in AAA.
It's no different this time. Your ex-girlfriend will cheat on you again. Your deadbeat cousin won't pay you back. The politician you voted in won't shake things up. Guys you love in Spring Training will play at their talent level come the regular season.
