Deep, as in Marianas Trench deep? Nick Putno, for steals alone. The last two professional seasons he recorded over 400 at bats, he stole 33 and 42 bases respectively, although both those totals came in the minors. If Rivas finally gets the boot and Punto takes over at second base for the Twins, a 30-steal pace, prorated for whatever portion of the season reamins is a good possibility.
He was 6-for-6 in the bigs last season, playing in only 38 games, and for a portion of those games he was a defensive substitute. He's 1-for-1 so far this year.
