Dunn's 2005 season was similar to the previous year, with a slight dip in production as he hit .247 with 40 home runs and 101 RBIs while once again leading in strikeouts (168) and strikeout percentage (30.9%). By reaching the 40 home run plateau for a second consecutive season, Dunn became the fourth player in Reds history to hit 40 home runs in multiple seasons.

Scott Hatteberg was a good player, then asked if the announcer was wearing a shirt. The clip went viral, and is frequently replayed on Cincinnati radio. In a 2012 poll, Reds fans voted the segment their all-time favorite "off-beat Marty" call.
2007 was a return to form for Dunn as he hit .264 while reaching the 40 home run and 100 RBI plateaus again, becoming the first and only Red to hit 40 home runs in four consecutive seasons. On October 31, 2007, Dunn's $13 million option was picked up by the Reds, making him the highest-paid player on the team.
Going into the final season under contract, Dunn hit .233 with 32 home runs and 74 RBIs, before being traded to Arizona.
In his 8 seasons with Cincinnati, Dunn hit 270 home runs with 646 RBIs, 755 walks and 1,212 strikeouts, all of which were within the top ten in team history.

He became the 12th player in Athletics history to hit a home run in his first at-bat with the organization. After a few productive games early on with the A's, Dunn's performance declined and became similar to his time with Chicago. In 25 games with Oakland, he batted .212 with a .316 on-base percentage, two home runs and 10 RBIs.
Dunn is one of fourteen players to have played 2,000 games without making the postseason, as Dunn played in 2,001 games, which was the longest for any active player at the time of his retirement . On the last day of the season, the Athletics clinched the second
AL Wild Card spot, which meant he was on a postseason roster for the first (and last) time. However, he did not make an appearance in the

for fourth-most all-time. Dunn's 222 strikeouts in 2012 represent the second-largest single-season strikeout total in MLB history (and the AL record) as of November 2024. Dunn was only one strikeout behind Mark Reynolds' MLB record, despite finishing the season with 13 fewer plate appearances.
Viewed in totality, Dunn was a prototypical " Three True Outcomes" hitter (that is, a player who frequently walks, strikes out, and hits home runs - in other words, a player whose batting outcomes are relatively unaffected by defensive luck). For his career, Dunn walked, homered, or struck out in 49.9% of his plate appearances. At the time of his retirement, Dunn's TTO percentage was the highest figure in baseball history for players with at least 4,000 career plate appearances. Major League Baseball's official glossary entry for "Three True Outcomes" cites Dunn as "one of the more famed three-true-outcomes players in recent history."

criticized Dunn's lack of clutch hitting and said, "He homers; he doesn't drive in runs." For his own part, Dunn said that he tried harder to get base hits when there were runners in scoring position, but "If it's first inning, two outs, nobody on, you know I'm not going to lie to you, I'm trying to get in the seats. And you know if I strikeout, okay, you know whatever."
Dunn was also criticized for his at times prolonged offensive slumps. He admitted that "When I'm going bad, I'm the worst player in the league. There's no arguing that. When I'm in that little funk that I get in, you know, every year for 'x' amount of times, I'm the worst in the league."
Fielding
Although Dunn's batting style was relatively unaffected by defense, he was himself one of the most woeful defenders of his era. He frequently surrendered hits and extra bases to opposing batters. He is graded harshly by modern defensive analytics, including models that penalize poor defensive plays more harshly if there are fewer outs and/or men on base (e.g., Defensive Runs Saved, used by Baseball Reference

.
Dunn's 2009 season was particularly woeful; his defense was rated at -35 runs by UZR and -43 runs by DRS. The latter was "the worst defensive season atingrelative to positional average in baseball history."
Because of Dunn's polarizing statistical profile, he is commonly regarded as both a poster boy for and casualty of the sabermetric

movement. At the time, sabermetric analysis had difficulty estimating the true value of defense with any precision, and analytically minded general managers tended to undervalue defense. Accordingly, Dunn's $112.7 million in career earnings nearly doubled those of his White Sox teammate Juan Pierre
Juan D'Vaughn Pierre (born August 14, 1977) is an American former professional baseball outfielder. He played in Major League Baseball (MLB) from 2000–2013 for the Colorado Rockies, Miami Marlins, Florida/Miami Marlins, Chicago Cubs, Los Angele ...
, even though Pierre's superior defense meant that the two players had similar career wins above replacement. SB Nation's Graham MacAree opined that if modern analytics had been in common use at the start of Dunn's career, Dunn would have quickly become a full-time DH. Instead, he was allowed to spend most of his career in the National League, which did not have the DH at the time, allowing his defense to drag down his overall production. McAree concluded that Dunn "just happened to be at the right time and the right place to be the poster child for baseball’s offensive metamorphosis while ''also'' a cautionary tale for what can go wrong with too-easy analytical thinking." FiveThirtyEight's Neil Paine agreed, writing that "Sabermetrics giveth and Sabermetrics taketh away. In the end, Dunn's career represents the maturation of statistical analysis in baseball."
During his time with the Cincinnati Reds, Dunn's defensive effort was frequently questioned. In 2007, Reds announcer Marty Brennaman complained that "I think he was overweight last year. He walks to his position. He walks off the field. You see no energy whatsoever and that disappoints the heck out of me." In addition, Toronto Blue Jays

general manager J. P. Ricciardi publicly insinuated that Dunn "doesn't really like baseball that much," although he later apologized for his comments. Following Dunn's departure from the Reds, CBS' Gregg Doyel harshly criticized Dunn and Ken Griffey Jr. for providing poor leadership, explaining that the new-look Reds were different from "the older, beer-bellied softball teams of recent years ... lounging on the clubhouse's leather couches, hitting home runs, misplaying balls in the outfield and thinking they had it all figured out, when all they knew how to do was lose."
However, Washington Nationals general manager Mike Rizzo defended Dunn's effort, calling him "the most misunderstood player I have heard about in recent memory. The way he was misconstrued n Cincinnatiwas almost unbelievable. He plays banged up. He'd go out there 162 games if you'd let him. He's the most consistent player in the game the last six years."
