In thirteen seasons Glaus hit.254 with 320 home runs and 950 RBI in 1537 games. In 19 postseason games, he hit.347 with nine home runs and 16 RBI. Glaus has been selected to four All-Star Games, three with the Angels and one with the Blue Jays.
Anaheim Angels
Glaus began his career with the Angels in and was installed as the team's starting third baseman in. Glaus had a breakout season in, becoming the all-time single season home run leader in Angels history with 47 while leading third baseman in adjusted range factor in 2000. Glaus participated in the 2001 MLB All-Star Game and posted his second consecutive 40 home run season with 41 on the year. In, Glaus failed to reach the 40 home run club for the first time since the 1999 season, but he managed to hit thirty home runs in helping the Angels make the playoffs for the first time in 16 years. The Angels beat the San Francisco Giants in 7 games to win their first World Series title in team history. Glaus was a key member of the Angels' 2002 World Series championship team and was named the Most Valuable Player of that series. Glaus followed that up with another All-Star year in. Glaus missed much of the season with a shoulder injury. 2004 was the last year of his contract with the Angels. As an established veteran, he was in demand on the free agent market and able to field lucrative offers for long term contracts. Although Glaus had spent his entire career an Angel, and was a fan favorite, the team decided not to pursue Glaus' return. Amid concerns about Glaus' future health after his injury, the team decided to go with the much lower-priced alternative of turning the third base position over to young prospect Dallas McPherson, whom they felt had a good chance to soon become as productive as Glaus had been. Glaus ultimately signed with the Arizona Diamondbacks for US$45 million over four years.
Arizona Diamondbacks
Glaus worked through his back problems in the season, with the Diamondbacks, by hitting 37 HRs with 97 RBIs. He also led the league in adjusted range factor, but his 24 errors tied him with David Wright for the most errors by a third baseman in the Major Leagues, and he had a Major League-low.946 fielding percentage at third. He was traded to the Toronto Blue Jays in the off-season along with minor league shortstopSergio Santos. The trade sent pitcher Miguel Batista and second baseman Orlando Hudson to the Diamondbacks. The Jays badly needed a power bat a year after letting go of Carlos Delgado, however the emergence of Hudson at second base gave the statistical advantage of this trade to the Diamondbacks.
Toronto Blue Jays
Although Glaus was converted from shortstop to third base in the minors, he started at shortstop for the Toronto Blue Jays against the Chicago White Sox on May 26, due to the demotion of shortstop Russ Adams. Glaus was not expected to do much fielding due to the fact the pitcher that day was known to induce many fly balls, instead of ground balls. This defensive alignment didn't affect his hitting, collecting 2 hits with a home run. Since then, Glaus made several starts at shortstop, usually when Toronto was facing National League opponents at their home ballpark, where there is no DH. After hitting 38 home runs and 104 RBI in the 2006 season, Glaus earned a single 10th place vote for the 2006 American League MVP Award. In 2006, Glaus had the lowest zone rating of any Major League third baseman. In Glaus's production was hampered all year by foot injuries and his production fell. On December 13, 2007, he was cited in the Mitchell Report.
St. Louis Cardinals
Glaus was traded to the St. Louis Cardinals in exchange for fellow third baseman Scott Rolen on January 14, 2008. This worked out well for the Cardinals, as Glaus did about as well as, or better than, his career rates in most offensive categories. Furthermore, Glaus committed only 7 errors in 146 games and led the league with a.982 fielding percentage at 3B. On September 3, 2008, he hit his 300th career home run off Doug Davis of the Arizona Diamondbacks in the third inning. He underwent arthroscopic right shoulder surgery on January 21,. The Cardinals initially expected him to be ready around the start of 2009 season, but after a setback in his rehabilitation he was placed on the 15-day DL; after another reassessment the Cardinals announced that they did not expect him to return until June 2009. On July 11, 2009 he was assigned to the Palm Beach Cardinals of the Florida State League on a rehabilitation assignment. He returned September 2, against the Brewers in the bottom of the 6th inning.
Atlanta Braves
Following an injury-shortened 2009 season with the St. Louis Cardinals, Glaus signed a one-year $1.75 million contract with the Atlanta Braves, a deal that allows him to earn an additional $2.25 million in performance and roster bonuses. He became the starting first baseman in 2010. After a rough April in which he hit below the Mendoza Line, Glaus rebounded to become Player of the Month in May, hitting.330 with 6 home runs and 28 RBI. As of August 9, Glaus was hitting.242 with 14 home runs and 63 RBI. Glaus's production faltered in July and August. After Atlanta acquired Derrek Lee on August 18 to play 1st base, Glaus was placed on the DL with knee fatigue. Glaus had a few setbacks, but returned to Atlanta in a back-up role behind Derrek Lee and rookie Freddie Freeman. Glaus made only one appearance at 3rd base during the regular season, but was used at 3rd in game 2 of the NLDS against the San Francisco Giants starting a key double play. Glaus then started game four of the series at 3rd.
