It's about that time, prematurely balding men and four girl readers. [player]Gregory Polanco[/player] is nearing his call-up date. He is basically a young version of [player]Starling Marte[/player]. As of this writing, he's 22 years old. I'm hoping he's still 22 years old when I'm done writing this post otherwise I spent way too much time on it. He can be a superstar, which has me excited. He won't be a superstar this year, which takes the wind out of my sails for redraft leagues. Usually when I'm talking about wind in my sails, I'm wearing only my boxers and just ate a can of beans, so maybe it's best if we ignore how much wind is in my sails. Polanco can hit 12 homers and steal 40 bags without killing you in average. Yes, I know, you love him too now. It's okay, just because your father never loved you doesn't mean you can't love another man. In Single-A, Polanco had 16 homers and 40 steals. In Single-A, Marte had 3 homers and 24 steals. Granted, Polanco had 200 extra at-bats in his Single-A year. Granted, Part II: Granted Lives; Polanco was two years younger in his Single-A year. Marte doesn't have anywhere near the plate discipline of Polanco, so, if anything, Marte will become a poor man's Polanco. Polanco has the kind of pedigree right now that could mean he's a top three rounder and one day supplanting The Dread Pirate as the best outfielder in Pittsburgh. I.e., The Sexy Dish That Ate Pittsburgh. Yes, I'm really excited for him. This past year between the two levels, he hit 12 homers and 37 steals while hitting .286. [player]Christian Yelich[/player] went from Double-A to the majors and hit fine. Lots of players do. The Pirates weren't that aggressive. If they were, then Polanco would've shot up my preseason rankings and I would've told everyone to draft him in every single league. Instead, Polanco went to Triple-A and continued to bash like your 12-year-old self idealizing Jose Canseco. As with rookies, you need to keep expectations in check. To misquote the immortal words of John Popper, "Nobody should think or expect too much while everyone is calling for the movie rights. Singing, 'Hey, babe, let's keep in touch. Hey, baby, let's keep in touch." He will be up in early June and now is the time to stash him. For 2014, I'll give him the line of 32/8/36/.250/15 in 300 ABs. Anyway, here's some more players to Buy or Sell this week in fantasy baseball:
