Los Angeles Dodgers On August 31, 2005, Aybar made his MLB debut with the
Los Angeles Dodgers. In his short time on the big league roster, Aybar made strides in impressing then-manager
Jim Tracy. In 86
at-bats, Aybar compiled a .326
batting average with 10
runs batted in and 3
stolen bases. After the 2005 season, Aybar was a candidate to start at third base for the Dodgers in 2006. However, in the offseason, the Dodgers signed free agent and former batting champion
Bill Mueller as their starting third baseman. After they also signed
Ramón Martínez to join
Óscar Robles in being the primary backups, Aybar found himself out of a job. His .216
batting average during spring training did not help his cause either. On May 12, 2006, Aybar received another opportunity to be the starting third baseman when Mueller was placed on the 15-day disabled list for
arthroscopic knee surgery, he was recalled from the Dodgers Triple-A affiliate, the
Las Vegas 51s.
Atlanta Braves On July 28, 2006, the Dodgers traded Aybar and relief pitcher
Danys Báez to the Atlanta Braves for infielder
Wilson Betemit. On April 18, 2007, Aybar was suspended indefinitely for unknown reasons. He was first suspended on April 15 for three games for failing to show up for treatments for an injured hand. This was a rare move by the Braves organization, and Aybar's lack of participation caused third baseman
Chipper Jones to remark "I didn't even know he was still on the team." The next day, Aybar's agent said that Aybar was struggling substance abuse. Aybar then failed to report to New York for a meeting with MLB officials on April 20. It was later revealed that Aybar was seeking help at a drug treatment facility. The Braves removed Aybar from the suspended list on August 4 and sent him on a rehab assignment in early August. However, on August 14, he underwent season-ending surgery for a stress fracture in his right hand.
Tampa Bay Rays On January 17, 2008, Aybar was traded with Chase Fontaine to the
Tampa Bay Rays for
Jeff Ridgway. On March 24, the Rays announced that he would be the team's starting third baseman. He held this position until
Evan Longoria was called up early in the season. Aybar then took the role of utility player. He finished the season batting .253 with 10 home runs and 35 RBI in 95 games. In the field, Aybar started 40 games at third base, 18 at first base, 14 at designated hitter, six at second base, and two at shortstop. Aybar hit a home run in the seventh and deciding game of the
ALCS, a 3–1 Rays victory that sent the franchise to the
World Series for the first time. On February 18, 2009, Aybar signed a two-year, $2.6 million contract with the Rays to avoid arbitration.
Yuma Scorpions Aybar was selected to play for the
Edmonton Capitals in the
North American League on February 11, 2011. However, he was released by the Capitals due to the Canadian government not granting him a visa. He later joined the
Yuma Scorpions in the same Independent league, which was managed by Jose Canseco. In 13 games he hit .302/.388/.372 with 0 home runs and 3 RBIs.
Delfines de Ciudad del Carmen On March 15, 2012, Aybar signed with the
Delfines de Ciudad del Carmen of the
Mexican League. He was released on April 22. In 7 games he struggled mightily going 4-24 (.167) with 0 home runs and 1 RBI.
Leones de Yucatán On March 27, 2015, after 3 years of inactivity, Aybar signed with the
Leones de Yucatán of the
Mexican League. He was released on June 9. In 35 games he hit .282/.353/.427 with 3 home runs and 17 RBIs.
Vaqueros Laguna On June 12, 2015, Aybar signed with the
Vaqueros Laguna of the
Mexican League. He was released on July 11. In 21 games he hit .314/.402/.514 with 4 home runs and 12 RBIs. == International career ==
