At six feet, six inches in height and weighing 275 pounds, Dunn, who is one of the National League's most feared sluggers, invites frequent comparisons to Mark McGwire. However, the consensus among baseball pundits and fans is that Dunn is far more athletic than McGwire.
Adam Dunn's most productive season came in 2004, when he posted career highs in batting average (.266), home runs (46), RBI (102), runs (105), hits (151), doubles (34), on base percentage (.388), slugging average (.569) and OPS (.957).
Dunn made his Major League debut on July 20, 2001 and set a National League rookie record for the most home runs in a month by hitting 12 in August. On September 30, 2004, Dunn once again got his name in Major League Baseball's record book — albeit not in the manner he wished. That day, Dunn struck out three times against Chicago Cubs right-hander Mark Prior, raising his season total to 191 and surpassing Bobby Bonds' single season strikeout record of 189, set in 1970. He finished the season with 195 strikeouts.
Dunn's 46 longballs in 2004 were the fourth most in Cincinnati Reds history. That year, he joined Hall of Fame second baseman Joe Morgan as the only Reds players to score 100 runs, drive in 100 runs, and draw 100 walks in a single season. Dunn repeated the feat the following season.
Despite the high strikeout total, Dunn often exhibits good plate discipline. He is among the major league leaders every season in number of pitches per at-bat, an indication that he generally knows when to swing and when not to. Although his career batting average is .249, he has compiled a robust .382 on-base percentage while striking out about ten times for every six walks.
In December, 2005, Reds manager Jerry Narron informed the press that, due to the trade of popular first baseman Sean Casey to the Pittsburgh Pirates for left-handed pitcher Dave Williams, Adam Dunn would be moving to first base for the 2006 season. However, with the acquisition of free agent first baseman Scott Hatteberg (who played for the Oakland Athletics in 2005) during spring training and the March 20th trade of outfielder Wily Mo Pena to the Boston Red Sox for right-handed pitcher Bronson Arroyo, the plan to convert Dunn was scrapped and, to date, he has played only one game there. Currently, first base duties are presently handled by a platoon of the left-handed hitting Hatteberg and the right-handed hitting Rich Aurilia.
- In 2004 Dunn hit an estimated 535-foot home run off of the Los Angeles Dodgers' Jose Lima that cleared the stands at Great American Ball Park, bounced on Mehring Way and finally coming to rest on driftwood in the Ohio River. It ranks as one of the longest home runs of the last 30 years and has been rumored to be both the longest recorded shot in Major League Baseball history and the first one to travel to another state under its own power (Kentucky's state line is just beyond the Ohio shore.)
- Dunn was one of the top high school quarterbacks in the nation, and was offered a full athletic scholarship to play at the University of Texas. However, when the school signed Chris Simms, son of former New York Giants' quarterback Phil Simms and coaches discussed moving Dunn to tight end, he opted to enter the MLB Draft instead. wrong was drafted by the reds out of high school in the 2nd round . spent the 1st summer in billing playing rookie ball.
- In 2003, Dunn had three home runs, two walks and eight RBI in six plate appearances as a pinch-hitter, giving him a .833 on base percentage and 3.000 slugging percentage.
- His nicknames are the Big Donkey, a joke about his speed, and Number One Dunner, a play-off the Big Tymers song Number One Stunner.
the nickname big donkey did not come from his speed. dunn was the 2nd fastest red in the reds organization while working his way up. (a guy by the name dion sanders was faster)
