Seattle Mariners (2005–09) in . Betancourt's initial calling card had been his fielding. In his first few seasons, he had been considered one of the best fielders in the game, combining excellent range, quickness, soft hands, hand-eye coordination, and a strong, accurate throwing arm. He was named one of the top fielders in baseball in a online fan's poll. In 2007, he made many good fielding plays; however, he suffered through spells of throwing wildness that season. Bad throws accounted for most of his 18
errors in the first half of , almost as many as his total of 20. He turned things around and made only 5 errors in the second half of 2007. His defense suffered in , with several fielding metrics calling him one of the worst shortstops in baseball. Betancourt has been a hitter with some gap power who rarely strikes out or walks. He has been criticized for his lack of plate discipline and inability to bunt. In 2006, he
walked only 3.0% of the time, the second-worst percentage in Major League Baseball. However, he only
struck out 9.7% of the time, one of the top 20 percentages. Betancourt was among the league leaders in batting with runners in scoring position and game-winning
RBI in 2007. In a late season game in 2007, former Mariner
Mike Blowers referred to Betancourt as being "unreal" when batting with runners on in close late games-a result at odds with his career statistics. He hit his first
grand slam in a 7–6 win against the
Chicago White Sox on 11 August 2007. In 2008, he again
walked only 3.0% of the time, the worst percentage in Major League Baseball. His
strikeout rate dropped to 7.5%.
Kansas City Royals (2009–10) On 10 July 2009, he was acquired by the
Kansas City Royals along with a portion of his salary for Minor League pitchers Derrick Saito and Dan Cortes. In 2009, he had the lowest on-base percentage of any starter in the major leagues, at .274, and the lowest slugging percentage in the American League with .351. In 2010, he hit an opening day home run off
Detroit Tigers pitcher
Justin Verlander, and went on to finish the season with a career-high 16 home runs. Many of his other statistics, including his batting average, on-base percentage, and fielding percentage, increased slightly from his 2009 numbers.
Milwaukee Brewers (2011) On 19 December 2010, Betancourt was traded to the
Milwaukee Brewers along with teammate
Zack Greinke and
US$2,000,000, reportedly to offset the buyout of Betancourt's club option in 2012, for
Alcides Escobar,
Lorenzo Cain,
Jeremy Jeffress, and
Jake Odorizzi. In 2011, he batted .252 with a .271 on-base percentage, and led the NL in sacrifice flies, with 10. He saw the fewest pitches per plate appearance of all major league ballplayers with 512 or more plate appearances, at 3.16. Betancourt hit his first career postseason home run on 9 October 2011 in a 9–6 win over the St. Louis Cardinals in Game 1 of the NLCS. Despite having the lowest on-base-percentage of any qualifying shortstop in baseball, he started a majority of the games for the Brewers. Against the Padres on 9 May 2011, Betancourt had one of the most acrobatic double plays of the season, as he turned a ball hit up the middle into a running, behind-the-back toss to Rickie Weeks as they turned the double play. Nevertheless, he posted below average defensive marks by a number of advanced metrics.
Return to Kansas City (2012) On 20 December 2011, Betancourt signed a one-year deal to return to Kansas City worth $2 million. He was released by the Royals on 14 August, becoming a free agent. He had played in 57 games, starting 51, with a .228 average and .256 OBP.

slash line of .212/.240/.355. His batting average and on-base percentage were the worst of his career, and his slugging percentage was well below his career average of .388. He would never appear in the MLB again after 2013. Throughout his MLB career, Betancourt directly earned approximately $16 million.
