Julio Teheran's first taste of the big leagues was a bitter one, but he has more than held his own in his first full year. Plus Anthony Rizzo, Martin Prado, Jorge de la Rosa and Anthony Rendon.

There were big expectations for Paul Goldschmidt entering his second full season, and he's answered the call. Plus Bailey, Melancon, Freese and Lagares.

Just when you thought Tim Hudson was a lock for double-digit wins and a sub-4.00 ERA, he has scuffled. Plus Shelby Miller, Ryan Braun, Gerardo Parra and Nolan Arenado.

Not only is Eric Chavez duplicating last season's success, so far he's improving up on it. Plus Marquis, Haren, DeJesus and Kubel.

Matt Carpenter had 33 extra-base hits in a part time role last year, helping make him a popular draft day choice, especially in NL-only leagues. Has he met expectations? Plus Jeff Locke, Jonathan Lucroy, Scott Feldman and Didi Gregorious.

No one expected what Starling Marte is doing so far in his first full season, outperforming teammate Andrew McCutchen. Plus Jon Niese, Chase Utley, Trevor Rosenthal and Jordan Schafer.

Martin on track for big year ... Russell Martin (C, PIT) opened eyes last year with a career-high 21 HRs. But the power burst obscured a .211 batting average -- the continuation of a five-year decline. Add that to a change of teams and it was hard to know what to expect from the veteran catcher.

Shin-Soo Choo rebounded nicely last year after injury cut short his 2011, and now his home is hitter-friendly Great American Ballpark. Plus Wainwright, Villanueva, Howard and Craig.

It took John Buck until June last year to record his 6th home run and 20th RBI. This year, it took 15 games. Is he capable of producing a breakout season? Plus B.J. Upton, A.J. Burnett, Daniel Murphy and Travis Wood.

Few expected Wilin Rosario to duplicate his Double-A stats in his first big league season. At age 24, could there be more to come? Plus Paul Maholm, Pedro Alvarez, Kevin Slowey and Travis Snider.

Jeff Samardzija became a rotation mainstay last season. But will he continue to be the Cubs' ace? Plus Andre Ethier, Lucas Duda, Wandy Rodriguez and Brandon Crawford.
