Friday Night Links: Goodyear, Dunn's clutchiness, and MLB customer service
Published 4/12/2008 by Justin at On Baseball and the Reds
... Baseball-Reference now offers splits by leverage, breaking up plate appearances into high leverage (LI above 1.5), medium leverage (LI between 0.7 & 1.5), and low leverage (LI below 0.7). Given that Dunn is the Reds' "unclutch" representative in the Great Clutch Project, we'd expect to see some historical performance dip in the highest of clutch situations, right? ...

... brawl, he needs to be hammering out his issues at Double-A Frisco or Triple-A Oklahoma. Ineffectiveness at the big league level does this ballclub absolutely no favors. Or perhaps he really is, at the end of the day, just the second coming of John Koronka: maddeningly tantalizing, but ultimately far too inconsistent to be considered as a reliable long-term rotation option.

Here's how WPA ...

Drew aquitted himself rather well. (And, yeah, I would’ve loved to see him pitch.) But how about that poor Dan Uggla? I felt bad for him. Really bad. But, in fairness. He played really badly.
