As I posted yesterday, Lowrie's range (RZR) in his short time at SS in 2008 would be AL-leading were he a regular.
Something interesting--if one looks at Lowrie's FRAA at SS, the best MiLB fielding stat I can access, it shows a big jump for Lowrie at Pawtucket:
[table] Level | Games | FRAA
A- | 40 | -3
A+ | 88 | -10
AA | 84 | -7
AAA | 31 | 8[/table]

In A and AA, Lowrie cost his team a run every 10-11 games at shortstop. In AAA, he's saved his team a run every four games or so. That's a big difference.
Maybe that superb RZR isn't just a small-sample fluke. Maybe Lowrie's finally caught on to playing shortstop...after all, he played mostly second base for Stanford.

FWIW, he actually pitched some in high school. His pro career was his first time playing SS regularly.
Cal Ripken Jr. wasn't a "true shortstop" either, but he did excel at SS given a chance. I see Lowrie as potentially being a more-than-adequate defensive shortstop, and right now Lugo isn't.
