I took a look at how John Jaso has done throwing runners out yesterday, so today, here's just about everyone else:
(All stats through April 26th)
John Jaso: 8 SB, 5 CS (38.5%)
Michel Hernandez: 2 SB, 0 CS (0%)
Alex Jamieson: 2 SB, 1 CS (33%)
Craig Albernaz: 3 SB, 4 CS (57.1%)
Matt Spring: 11 SB, 1 CS (8.3%)
Ian Paxton: 1 SB, 2 CS (66%)
Nevin Ashley: 6 SB, 8 CS (57.1%)
Stephen Vogt: 0 SB, 3 CS (100%)
Jake Jefferies: 10 SB, 4 CS (28.6%)
Mike McCormick: 7 SB, 5 CS (41.7%)
The only one who's really struggling is Matt Spring. Part of that might be that Montgomery's staff is easy to steal on, but between Paxton and Albernez(who has split time between AA and AAA), 4 runners have been thrown out in 7 attempts. So it looks like Spring's the problem there.
The Stone Crabs have done a great job killing the running game, throwing out 65% of base stealers. The report on Jake Jefferies out of college was that his catch-and-throw skills were enough to offset an average arm, but a CS% under 30 is a bit of a red flag. Of course, it's early.
Tomorrow I'll turn the tables and see how our baserunners have fared against opposing catchers.
