Eddie Rosario hit 27 homers and stole nine bags last year. This should disqualify him from being a sleeper. You might be thinking. "Sure, uh-huh, but what was his average?" He hit .290. So, now you might be thinking, "Okay, okay, got it, but what was his BABIP? Was he lucky?" His BABIP was .312, his career BABIP is .325. You might now be thinking, "Fine, but the Twins, I mean, blech, right?" The Twins were the 7th best offense in baseball last year, just ahead of the Diamondbacks, Rangers and Red Sox. Now, you might be thinking, "Well, Rosario isn't a big part of that offense." He's their cleanup hitter. Now, you might be thinking, "His HR/FB must've been insane." It was 16.4%. Far from insane. Now you might be thinking, "He hits a lot of ground balls. He's gotta, right?" About the same as Gary Sanchez and Travis Shaw. "He strikes out a lot?" Nope, about the same as Freddie Freeman. "I feel like he's been around a while, he's old, right?" He's 26. "So, why is he a sleeper?" Better yet... So, what should we expect from Eddie Rosario for 2018 fantasy baseball and what makes him a sleeper?
