Edwin Jackson, RHP, Cubs (21.9 Percent Owned)
Over the past six weeks, Jackson's ERA (3.42) has looked much more like his FIP for the season (3.55), so don't get stuck on that actual 4.89 ERA.
Justin Maxwell, OF, Astros (1.4 Percent Owned)
Preseason sleeper with 20-20 potential missed almost two months with injury early on, but Maxwell finally hit his second homer over the weekend and has stolen two bases in his past six games, so don't forget about him entirely.
Henry Urrutia, OF, Orioles (1.0 Percent Owned)
A 26-year-old rookie, Urrutia (pictured) has a nice lefty swing for contact and extra-base power, and he looks to be in line for regular action as the DH in a potent Orioles' lineup. Just don't expect him to break out quite like that last Cuban phenom.
A.J. Ramos, RHP, Marlins (0.3 Percent Owned)—hot and closer?
If the Marlins wind up trading closer Steve Cishek, Ramos should be the guy stepping into the role, considering he compiled 83 saves—and a 2.26 ERA and 12.3 K/9—in four years in the minors and hasn't allowed an earned run over his past 18.2 innings.
Taylor Jordan, RHP, Nationals (1.3 Percent Owned)
The 24-year-old has shown good control in both the minors (2.1 BB/9) and in his first 35 innings in the majors (1.3), and he had his best start yet on Sunday: 6 IP, 5 H, 1 ER, 7:1 K:BB.
Jake Marisnick, OF, Marlins (0.6 Percent Owned)
Finishing up with a fourth straight rookie, Marisnick rates the highest of this quartet in prospect rankings, but he's also easily the most raw at 22, as his 2-for-22 showing in his first week proves. He does have 20-20 potential in the future, though, so keep an eye out if he gets hot.
