Adam Dunn (born November 9, 1979 in Houston, Texas,) is a Major League Baseball outfielder for the Cincinnati Reds. He bats left-handed and throws right-handed.
In his five-season career, Dunn owns a .901 OPS with 158 home runs and 374 runs-batted-in in 501 games.
He was elected to the 2002 National League All-Stars team.
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.
