Putting the likelihood of Wells also contracting Rick Ankiel disease aside... Hill 2006: 26 years old, 99.1 IP, 4.17 ERA, 1.22 WHIP, 90 K, 39 BB Hill 2007: 27 years old, 195 IP, 3.92 ERA, 1.20 WHIP, 183 K, 63 BB Wells 2009: 26 years old, 95 IP, 2.84 ERA, 1.15 WHIP, 60 K, 21 BB At the same point in their careers, Hill never pitched as well for as extended a period of time. The 4.17 ERA in 2006 was inflated because he struggled in an earlier call-up. He was lights out after returning for good over the last month or so of the season.
