Just for fun, let me update the comparisons from the initial post in this thread (dated Aug 10, 2013):
Papelbon in 2006: 68.1 IP, 40 H, 15 BB, 75 K, 3 HR, 0.776 WHIP, ERA+ 517
Eckersley in 1990: 73.1 IP, 41 H, 5 BB, 73 K, 2 HR, 0.614 WHIP, ERA+ 603
Uehara in 2013: 63.1 IP, 29 H, 9 BB, 87 K, 5 HR, 0.600 WHIP, ERA+ 369
Over the past month or so, his WHIP has dropped by 0.107. That's impressive. What's even more impressive
is that if you compare this post to my initial one, you'll see that Uehara has given up -2* walks over this
span. How many pitchers can retroactively erase runners from the basepaths, huh?
(*) Or maybe I typed in the wrong value earlier. But I like the "retroactive erasure"** explanation better.
(**) which would be an awesome name for a band.
