Just about every system in baseball has one or two 80-grade runners that make stop watches start smoking. Nunez is one of those players, and he actually breaks the traditional scouting scale. I have had scouts report sub-3.70 times to first base for Nunez, making him easily the fastest player in the system.
Salgado is another 80-grade burner that can fly down the line and cover tons of ground in the outfield. He is extremely raw in terms of his ability to utilize his speed but he has the potential to be a game changing defender and base runner.
You can toss Iorg, Gibson and Polk in a hat and pick one out and I wouldn't argue with the ordering of these players on this list. I give Iorg the nod because of his instincts and ability to put his raw speed to work. He grades as a 65-70 runner on the 20-80 scouting scale. Gibson and Polk both rate in the same vicinity.
Johnson and Loy will both turn in 60-grade times from home-to-first and both can be very strong base stealing threats because of their ability to eat up real estate. As plus runners, both players can utilize their speed to impact the game and that may give them an added edge in getting to the big leagues.
Both Castro and Fuentes will flash plus running times on occasion but neither is consistent in their ability to get out of the box. Once underway both players are very good runners that merit consideration for the back of this list, and with more experience they could sneak their way onto the list.
Machado has the best chance to vault himself from this portion of the list to the loftier ends, and he could do that with some added strength and additional instruction. Both Castillo and Rockett will toss in the occasional 60-grade time, but much more frequently sit in the 55 speed range. Write and Henry are both solid-average runners with good instincts on the bases and in the field.
