A lot of people, including me, were surprised by the Twins decision to add Estarlin de los Santos to the major league roster. From the description, de los Santos is a slick fielding shorstop with some bat. His numbers at Fort Myers certainly indicate that. He hit .290/.330/.397 with 11 SB and 4 CS in 262 at bats. That may not sound impressive, but that gave him the second highest batting average on the team after Ben Revere and 24th in the FSL. He is no Revere with the bat, but if he is a plus major league shortstop defensively, his bat looks like it will also be a plus at shortstop.
Of course de los Santos hasn't played above A-ball so he has a long way to go. He hit better than Steve Singleton at Fort Myers despited being a couple years younger. Singleton was promoted to New Britain during the 2009 season in order to make room for de los Santos at Fort Myers. Singleton's offensive production there caught the attention of a lot of folks in the blogsphere, but apparently not the major league scouts as he was left unprotected and unclaimed in December Rule 5 draft.
Here is a link to an article in the New Britain paper with Jim Rantz discussing the players New Britain will see in 2010, including de los Santos.
