We're spinning around every division in baseball for their biggest fantasy baseball stories and players.

AL East  | Central | West ... NL East | Central | West

Arrivals

1B/OF Ian Desmond, Rockies: New home improves his chances of repeating most of huge 2016 year, but risks with plate discipline remain. OBP leaguers shouldn't overpay.

RP Mark Melancon, Giants: K/9 not the greatest among stoppers, but control is sparkling, and his new home will keep him as a top-10 fantasy closer.

2B Logan Forsythe, Dodgers: Coming off his career-high in homers, he goes to another poor park for hitting. Still, it's a better lineup, and he's a solid, though unspectacular, fantasy middle infielder.

SP Taijuan Walker, Diamondbacks: Homer-happy track record says beware with his move to Chase Field, but his electric arm could overcome that. If everyone else in the draft room is scared, buy him on the cheap.

RP Greg Holland, Rockies: He's likely set to start the year as Adam Ottavino's backup, but if he regains the top closer form he had before 2015 Tommy John surgery, that leash will tighten.

SS Ketel Marte, Diamondbacks: He'll compete for work at shortstop and possible second base, though he carries a potential speed bonus late in drafts.

C Chris Iannetta and Jeff Mathis, Diamondbacks: Arizona's new analytics-minded approach includes bringing aboard these capable pitch-framers. Their pitchers will benefit more than they will in fantasy, as there's a sleeper who's going to start ahead of whichever wins this battle.

X-factors

OF A.J. Pollock, Diamondbacks: He accomplished little during his brief September return from a fractured elbow, but he enters 2017 with the same elite five-category upside he delivered in 2015 and in pieces during previous seasons. In Round 2, he's golden.

SS Corey Seager, Dodgers: He won't offer stolen bases, but everything else makes him a top-three fantasy shortstop.

1B Wil Myers Padres: Breakthrough 2016 accurately reflected his strengths (power and speed) and flaws (batting average). Count on a similar follow-up.

SS Trevor Story, Rockies: Watch his spring performance as he rehabs his thumb surgery. His woeful plate discipline and home and road splits present more cases for downside. Still, that power and speed could play handsomely near the bottom of the top 50 fantasy picks.

OF Carlos Gonzalez, Rockies: Despite his elite performance in the last two seasons, he can be had at a bargain in many draft rooms. His owners, however, must recognize the possibility Colorado trades him if they fall out of contention.

SP Rich Hill and Julio Urias, Dodgers: Hill's poor health record and Urias' likely restrictions on innings limit their immediate ceilings, but they could be absurd value picks.

Breakouts

OF David Dahl, Rockies: Ian Desmond playing first base cements Colorado's desires to start Dahl almost every day. His power-speed combo looks ready to thrive, as long as his owners can handle a clip of closer to .270 than .300.

OF Manuel Margot and Hunter Renfroe, Padres: Margot will provide homers and steals (definitely more steals). Renfroe could have thunderous pop. Which will your team need in the middle rounds?

SP Matt Moore, Giants: For all his good seasons, Moore hasn't had that one with across-the-board dominance. Moving to the NL and one of the league's best pitcher's parks sets him up to finally shine in 2017.

SP Jon Gray and Tyler Anderson, Rockies: Colorado finally has decent pitching! Maybe avoid starting them at home, but their approaches – notably Anderson's groundball skills – make them worth owning.

Sleepers

SP Robbie Ray, Diamondbacks: Need strikeouts? He's your man. Need anything else? You may have to wait for him to learn on the job. But K's are worth a depth pick.

SP Alex Wood, Dodgers: There may be at least one chance for him to join the rotation. His dirty arsenal could play well again in his advantageous pitcher park. Don't lose track of him.

3B/OF Brandon Drury, Diamondbacks: He'll plug in at several positions each week and has the pop to do the same for deep mixed lineups.

OF Yasiel Puig, Dodgers: As with Jason Heyward ... I mean, you have to take a chance in the waning rounds, right?

C Austin Hedges, Padres: After his huge step forward in homers last year, he's a prime target toward the bottom of the board in two-catcher mixed leagues.

C Chris Herrmann, Diamondbacks: Power-fueled backstop looks like the early starter. Two-catcher players should pay attention.

C Tom Murphy, Rockies: Does Colorado favor Tony Wolters' work behind the plate or Murphy's offense? Playing time concerns aside, two-catcher and NL-only competitors can try his power.

2B Ryan Schimpf, Padres: Power-first (-only?) middle infielders are worth something in deep leagues.

OF Alex Dickerson, Padres: Too many Friars? Maybe, but also another intriguing piece for leaving the yard.

SP Luis Perdomo, Padres: His impressive 2.31 BB/9 in 20 starts could point to something useful – someone among Padres starters has to, right? Maybe Jhoulys Chacin, too? Anyone? Yuck.

Undervalued

3B Justin Turner, Dodgers: Basically expanded on power growth in 2015 -- legit, because of changes he made to his swing (specifically his leg kick) -- and at this deep position, he continues to get lost in the crowd.

3B Eduardo Nunez, Giants: There'll be doubters, but no one should question his ability to steal bags.

Overvalued

C Buster Posey, Giants: Batting average and playing time are studly among catchers. But  everything else looks more questionable than ever. Is he still worth that reach? The answer leans "no" now more than ever.

OF Yasmany Tomas, Diamondbacks: Homers seemed a bit too good to be true, especially with his weak GB/FB. He hits the ball hard, though anything below 25 home runs severely limits the hacker's value.

On the rebound

SP Zack Greinke and Shelby Miller, Diamondbacks: New organizational philosophy could be huge for their pitchers. Greinke remains a top-20-something starter. Miller could be a steal in the "last year's trash" vein – a nice balance between his inflated 2015 and his exaggerated disaster of 2016.

1B Adrian Gonzalez, Dodgers: Still a sound bat, but losing ground in power at a stacked position.

OF Hunter Pence, Giants: Another injury-riddled year drives his price down again. He'll need nearly a full season to reach 20 homers again, but he's a fine depth piece.

Position battles to watch

Dodgers No. 4 and  5 SP: Who'll get a leg-up among Urias, Wood, Scott Kazmir (ribs), Brandon McCarthy and Hyun-Jin Ryu? At least they have ample depth.

Diamondbacks second base and shortstop: Drury, Marte and Chris Owings (stash for steals) may trade at-bats in the middle infield.

Diamondbacks No. 5 SP: Archie Bradley and Braden Shipley – perhaps Matt Koch, too – are both youngsters with command to polish. The winner could enter fantasy sleeper consideration.

Giants left field: This may be a Jarrett Parker/Mac Williamson platoon.

Padres SP: Might as well list every spot up for grabs. Seriously.

Closer chronicles

Kenley Jansen returned to the Dodgers. He's a stud.

Rodney had a great first half last year but fell off and then became the setup man in Miami. There's fantasy value in his dirt-cheap price, though his erratic performance justifies that deflated cost.

The Padres may rely on Brandon Maurer, but Carter Capps may be the better fantasy pick as a dice roll.
