Vidal Nuno made some impressive skill gains late in 2014 that could help him produce some nice profit for his owners in 2015.

It's a deep field, but GMs are often digging even deeper. We'll break it on down.

Joe Mauer's (1B, MIN) .300 BA went missing in 2014—without catcher eligibility, what's he worth? Also, Buchholz, Al. Ramirez, Kiermaier, Kelly.

Steve Cishek's closer skills in 2014 ranked up there with just about anybody. Plus, Josh Collmenter, Adrian Gonzalez, Brandon Belt, and Christian Yelich.

Jordan Zimmermann had a tremendous 2014 season. Can he repeat in 2015? Plus, Jonathan Lucroy, Henderson Alvarez, Matt Carpenter, and Addison Reed.

David Ortiz leads the Red Sox in their attempt to again go from worst to first in the AL East. Also, Verlander, Gregorius, J. Vargas, and Flowers.

Here are the highest skills non-roster invitee relievers, and a couple with not so high skills but are still getting selected in drafts.

Brian Dozier was the only 2B to go 20/20 last season. Where does he rank entering 2015? Plus Hisashi Iwakuma, Shin-Soo Choo, Andrew Miller, and Mike Zunino.

Marcus Semien's power/speed combo and solid plate skills make him an attractive LIMA target.

Josh Tomlin quietly showed elite command with CLE in 2014. With his strong skill base and unknown role, he enters 2015 as an intriguing LIMA target and profit center.

Breaking down the outfield. Who's going too early? Where are the bargains?
