5. Trevor Rogers, LHP, Marlins (graduated from Top 30)
Even when he was posting a 6.11 ERA in his first taste of the Majors last year, Rogers was no stranger to the strikeout, having fanned 39 in 28 innings. His affinity for the K has continued with a rookie-best 16 in 10 innings, and the rest of his numbers have caught up as well, such as a 1.80 ERA and 1.10 WHIP. The 23-year-old southpaw is getting whiff rates above 50 percent on both his mid-90s fastball and low-80s slider, and most recently, those two offerings (along with a changeup) helped him outduel Mets ace Jacob deGrom last Saturday. Rogers won a rotation spot for Miami coming out of Spring Training and doesn't look like a pitcher who will give up that placement anytime soon.

7. Jazz Chisholm Jr., 2B/SS, Marlins (No. 4/MLB No. 58)
Since winning the second-base job out of the spring, Chisholm has solidified his place as one of the most exciting players on the Marlins roster and even the Majors at large. He proved that by taking a 100.4 mph pitch from deGrom deep into the Citi Field upper deck over the weekend. His plus speed also came into play when he stole second (despite a pickoff attempt from Rays lefty Rich Hill) and third on successive plays on April 3. In fact, those two thefts make Chisholm the only rookie with multiple steals at this stage of the early season. His .888 OPS -- aided by six walks in 30 plate appearances -- also places fifth among qualified rookies. (That comes despite just a .217 average.) His combination of pop, speed and middle-infield play could make Chisholm a South Beach sensation for years to come.
