There’s a reason — beyond the obvious talent — that Giancarlo Stanton, Justin Upton and Mike Morse generated so much trade talk among Yankees fans this winter. A big, power-hitting, prototypical corner outfielder would fit incredibly well on this roster. The minor league system might have a legitimate outfield slugger on the way, but he’s at least a year away, and for the time being, the Yankees outfield is filled with two small-ball players and one all-or-nothing free agent to be. Those are three legitimate pieces, but the Yankees outfield could certainly make room for one of Brian Cashman’s big, hairy monsters if he could find one.
 Curtis Granderson / Ichiro Suzuki
Signed through 2013 /2014
We know Suzuki will be in right field. We can only guess whether Granderson or Brett Gardner will be in left (as I wrote a couple of days ago, I’m heading into spring training expecting Gardner to shift to center). Either way, the Yankees are going to have considerable speed in their outfield and should cover a lot of ground. They’re going to count on Gardner and Ichiro to run on offense, and on Granderson to hit home runs. What’s still unclear is who they’re going to count on to hit against lefties. Matt Diaz is coming to camp on a minor league deal, and Russ Canzler is going to try to win a job in spring training, but Cashman has made no secret of the fact he’d like to add another right-handed hitting corner outfielder. Nick Swisher gave the Yankees a steady right field presence for four years, and he’s been difficult to fully replace this winter.
 On the verge
Maybe Tyler Austin can play his way into the big league picture this year, but it’s more likely that immediate help will have to come from either Zoilo Almonte or Ronnier Mustelier, two players who really weren’t even worth watching two years ago. Almonte was signed way back in 2005, but he didn’t put himself on the map until 2011 when he cut down on his strikeouts and hit .276/.345/.459 between High-A and Double-A. His power numbers went up during a full Double-A season last year, and now he has a 40-man spot with a Triple-A job on the way. He’s a switch hitter who was especially good against righties last year (it hasn’t always been that way). Mustelier is a Cuban defector who didn’t join the Yankees until 2011 when he was already 26 years old. He’s too old to be considered a typical prospect, but he’s hit .324/.378/.497 through two pro seasons, including a pretty good 89 games in Triple-A last year. He’s played some second base and center field, but Mustelier’s ticket to the big leagues might be his ability to play all four corners. He’s kind of a less proven version of Canzler, who’s probably higher in the pecking order. Under certain circumstances, center fielders Melky Mesa and Abe Almonte could also factor into the corner conversation.
 Deeper in the system
Austin is easily the top corner outfield prospect in the system, and he appears to have been a 13th-round steal. Drafted out of high school in 2010, Austin was the unquestionable breakout star of the Yankees minor league system last year. He hit .322/.400/.559 while climbing all the way from Charleston to Trenton. Despite that little bit of Double-A experience, the Yankees are considering sending Austin back to High-A to open this season. If he repeats last year’s results, he won’t stay there for long. Austin’s breakout season easily overshadowed Ramon Flores, a left-fielder who has a knack for getting on base (.362 on-base percentage in his minor league career). Flores was added to the 40-man this winter and is ticketed for Trenton. It’s hard to mention all of the system’s mildly interesting corner outfielders — converted third baseman Rob Segedin, under-the-radar Cuban prospect Adonis Garcia, does-a-little-of-everything Ben Gamel, and 2012 draftees Taylor Dugas and Nathan Mikolas are names worth knowing — but I’ll save room for Jake Cave, the Yankees sixth-round pick in 2011 who’s hardly played since being drafted because of a knee injury. Cave could have been drafted as either a left-handed pitcher or an outfielder, but the Yankees liked his bat. There’s upside to him, just no professional track record.
 On the move
College outfielder Rob Refsnyder played right field for the Yankees Low-A team last year but seems likely to shift to second base next season. On the flip side, long-time middle infielder Jose Pirela began to see considerable time in left field last year and kept at least a little bit of prospect status alive with a strong Double-A season. The Yankees have shown a willingness to move players into the outfield corners when necessary — that’s how Austin got there after signing as a corner infielder — and they could eventually do that with last year’s second-round pick Austin Aune, who will first get a chance to sink or swim as a shortstop. Obviously, if top center field prospects Mason Williams and Slade Heathcott each get to New York, one of them will have to shift to left field.
What to watch
The development of Austin is among the most interesting aspects of the Yankees system this season. Last year was a revelation, the kind of year that suggested he just might be a real life, in-house, power-hitting corner outfielder that can rise through the system and get to New York within two years. That would be huge for the Yankees. For now, the thing to watch is the Yankees on-going pursuit of a right-handed outfield bat and the how-long-can-he-last uncertainty of Ichiro’s two-year deal.
