Nava has a great swing left handed, and I've said before he reminds me of the Young Yaz with that swing. He has patience at the plate, and could be the very good hitter at the ML level he showed in the lower minor league levels. He is a line drive type of hitter--as Yaz was when he first came up. But Yaz opted for more HRs after a couple years, and his batting average and OBP came down. That's where the simlarities end, as Nava still has a lot to prove at this level. But he has hit HRs the last few days from both sides of the plate--which is a good sign.
I saw him a few years ago in a Pawsox game with the Scranton Yankees. He and J. Montero had big nights, but Nava looked like the better hitter.Hit a rope down the RF line for a HR. Salty was catching.
Yankee players get a lot of hype from that NY based network media (the Boston media sometimes as well), and Montero doesn't appear to be as advertised in Seattle.
Right now, with Nava and Iglesias standing out (Iggy is hitting like a young ARod in Pawtucket!), Cherington has some rethinking to do about some of those FA signings. Good to see Webster is getting a shot tonite. They need to upgrade those starters behind Lester and Buchholz.
