Scouting report from Major League Umpires' Performance, 2007-2010, by Andy Goldblatt:

Beyond Jon Lester, there probably aren't many pitchers happy to see Knight. His remarkably consistent BB/9 is three percent higher than average. And though his K/9 has increased over the years, his overall score of 13.36 is three percent lower than average. ... Although Knight gets his share of grief from fan blogs, his ejection rate is below average at 1.6 perent.

Scouting report from some angry Tigers fans:

Average K/9 (2011): 13.9

Average BB/9 (2011): 6.3

Sample PITCHf/x strike zone: May 8, 2012. All those green triangles inside the strike zone are what really pissed off Leyland and Verlander.

True fact: Had a 13-game stretch in 2008-09 where the home team won 13 straight games that he called.

On umpiring: "It was awesome. It was unbelievable. It was the experience of my life so far."
