Iannetta is second only to Mike Trout for the team lead in on-base percentage at .369. It's a mark that would lead Major League catchers -- one point better than Brewers standout Jonathan Lucroy -- if Iannetta had enough at-bats to qualify, and a mark that is slightly higher than his career rate of .356.
Among those with at least 2,500 plate appearances since 2006, Iannetta ranks 13th in plate appearances per walk and 18th in pitches seen per plate appearance.
"It's hard enough for me to be successful, even on my own," Iannetta said. "If I was getting myself out, it became almost impossible. So I had to take away the one thing that I could control, and that was limiting the things I can get myself out by chasing pitches and falling behind in counts. If I got into a 1-1 or 2-1 count, kind of making sure the count fell back in my favor instead of going 1-1 to 1-2."
