Per The Hardball Times:

Citing the clubhouse as a hotbed of negativity, Snell took his 2-8, 5.36 ERA down to Triple-A Indianapolis where he chalked up a 0.96 ERA in six innings.

On a related note, Roy Halladay’s 2009 AL All-Star ERA is 9.00 in two innings. Maybe the Mariners can now trade Snell for Halladay?

p.s. How does one chalk up a 0.96 ERA in six innings? Was .36 of the run unearned?
