Players in the organization are ranked according to steals per game times success rate. Everyone with 8 or more steals at the close of business on July 8 is shown in the current update (7/8).
All of the Peoria players except Easterling are new to the list. Andreoli played eight games for Peoria in 2011 but did not make the list at that time.
As usual, this is a good list. As much as anything else I can think of, the right-hand column of this table gives you athleticism reduced to a number. The list has always featured legitimate, sought-after prospects like Campana, Guyer, Lee, Fuld, Jackson, Lake, Thomas (Tony).
Putting aside Campana (already a major leaguer), I would cite four names in the top six as serious prospects: Baez, Alcantara, DeVoss and Jackson.
Note 7/30:
The current table includes everyone from Peoria through Iowa with a dozen or more stolen bases.
Baez and Alcantara share the highest success rates with 86%, but Szczur steals a base in just under half his games (48%). Only Andreoli (43%) comes anywhere near that rate of steals per game. The decisive rightmost column in the table factors in both success rate and steals per game. (We feel we should recognize players who just hate to see second base unoccupied while they are on first.)
Note 8/15:
Tony Campana celebrates his return to Iowa by stealing bases at a faster clip than anyone else in the organization. Andreoli passes Szczur and Baez to move into second place.
Note 8/23:
Here I have accepted players with 10 steals or more (at Boise or above). Added to the list this week are Saunders, Darvill and Ha. Saunders goes to the head of the class, just below Campana.
