In a post on MLB Trade Rumors, Coley Ward wrote about potential free agents when the season ends and he mentioned Adam Dunn, who's having a tough year when it comes to making contact with the ball, but is burning the home-plate-to-first-base path with 21 walks in 53 at-bats (28 BB%), on pace for 207 walks if he records the same amount of AB that he did last season (522).  That's 10% more walks than his career average (17 BB%).

While an impressive number, it still would not be a record, with Barry Bonds getting 232 in 2004, on top of his 120 intentional walks.  He batted for a ridiculous 1.422 OPS that season.

Just take a moment to re-read the last two sentences; these are just insane figures!!

Just for fun, here are the all-time leaders in walks and intentional base-on-balls:
