Trumbo said that over his career he thinks his home runs have come in bunches. It's something he has been at a loss to explain, and he realizes that it's something he's better off not putting too much thought into.
"You want to be consistent," he said. "You just play. You go out there and play, and things shake out at the end of the year."
Trumbo's overall production is very consistent.
In 2011, Trumbo hit 29 homers and followed that up with 32 in 2012 and 34 last year.
