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

Nelson went over to the hitters' side in 2009. ... His his 2009 numbers been at all consistent with the other three seasons, his R/9 would be the lowest of all umpires ... Nelson has an average fuse, compiling a career ejection rate of two percent.

Scouting report from angry Red Sox manager Bobby Valentine:

Guys battled their butts off, that's all I know. That's a damn shame. Fucking umpire can't make a right call and get help to get it done. It's a damn shame is what it is. Be stubborn. It's not his job to call the frigging play. Just get help. It's a damn shame is what that is. It's a damn shame.

Sample PITCHf/x strike zone: August 20, 2010. Nelson ejected Baltimore's Nick Markakis for arguing a called strike, but the pitch was several inches feet off the plate.
