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.
Average K/9 ( 2011): 15.7

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.
True fact: A native of Minnesota who graduated from Bethel University in 1987, Nelson worked home plate for the first regular-season game at Target Field.
On umpiring: "My skill is balls and strikes, safes and outs. I enjoy the challenge of competing against perfection."
