Are opposing teams running more on the Twins, and especially on Joe Mauer? It sure seems like it has been more of a problem this year.
It turns out that Mauer has thrownout 9 of 32 stolen base attempts, which is just 28%. That's actually above last year's 26% rate, but below his career rate of 37%. But it appears that any stolen base problems the Twins are having aren't really the fault of the catchers. They fall primarily on one pitcher'a shoulders, which becomes apparent when you look at how many stolen base attempts and stolen bases each has faced.
Nick Blackburn - 1 attempt, 0 stolen bases
Scott Baker - 3 attempts, 1 stolen base
Francisco Liriano - 4 attempts, 3 stolen bases
Kevin Slowey - 7 attempts, 5 stolen bases
Carl Pavano - 17 attempts, 15 stolen bases
Pavano has given up 60% more stolen bases than the rest of the starting staff COMBINED.
