José Dariel Abreu Correa (born January 29, 1987) is a Cuban-born professional baseball first baseman who is a free agent.

After 48 games in 2008–2009, he was batting .345/.368/.600, earning the infielder a spot on Cuba's provisional roster for the 2009 World Baseball Classic.

In 2009–2010, Abreu produced his best year to date, hitting .400/.555/.822 with 82 runs, 30 homers, 76 RBI and 74 walks to 49 strikeouts in 89 games.

Abreu was Cuba's starting first baseman when they won the 2010 Intercontinental Cup, their first Gold in an international tournament in three years.

In the finale, he went 1-for-3 and scored the first run in the victory over the Dutch national baseball team; he doubled off Rob Cordemans in the third and came home on a Yorbis Borroto hit.

In the 2010 World University Baseball Championship, he posted the best average by going 10-for-18 with two walks, a double, triple, four homers, nine runs and 12 RBI in six games as Cuba won the Gold.

[1] Despite missing 23 games due to bursitis in his shoulder, he broke Despaigne's home run record (as did Yoenis Céspedes—both hit their 33rd on the season's last day).

Abreu led the league in average (.052 over Michel Enríquez), slugging (by .212 over runner-up Frederich Cepeda), intentional walks (21) and homers (tied with Yoenis Céspedes), was second in RBI (6 behind Céspedes), tied for eighth in runs with Donal Duarte, seventh in total bases (209) and fourth in times hit by pitch (21).

He won Cuban National Series Most Valuable Player Award, the second MVP from Cienfuegos, following Pedro José Rodríguez, Sr., by 31 years.

[2] In August 2013, rumors began circulating online that Abreu had defected from Cuba to pursue an MLB career.

[2][6] On the White Sox, Abreu joined fellow Cuban players Alexei Ramírez, Dayán Viciedo, and Rule 5 draft pick Adrian Nieto.

On April 8, 2014, Abreu hit the first two home runs of his career in a game at Coors Field, helping his team to defeat the Colorado Rockies, 15–3.

On April 25, 2014, he captured his eighth home run of the year off Chris Archer, tying the rookie record for homers in March–April.

Later that night, Abreu recorded his third multi-homer game with a walk-off grand slam versus Tampa Bay Rays pitcher Grant Balfour giving him nine homers in his first month in the Major Leagues, surpassing the record of eight shared by Albert Pujols (2001), Carlos Delgado (1994), and Kent Hrbek (1982).

In the second at bat after his return, Abreu hit a two-run home run off Dodgers ace Clayton Kershaw.

[16] On November 22, Abreu signed a three-year contract with the White Sox worth $50 million, superseding his previously accepted qualifying offer.

[17] On August 22 and 23, 2020, against the Chicago Cubs, Abreu tied an MLB record by hitting a home run in four straight at-bats.

In Game 1 of the AL Wild Card Series against the Oakland Athletics, Abreu hit his first postseason home run in his second at-bat off Jesus Luzardo.

For his efforts during the regular season, Abreu was named the AL MVP, becoming the first White Sox player to win the award since Frank Thomas in 1994.

Abreu also became the fourth different White Sox player to win AL MVP joining Thomas, Dick Allen, and Nellie Fox.

[22] On April 14, 2021, in a game against the Cleveland Indians in top of the 9th inning, Abreu made a play at first base and was credited with saving a no-hitter for Carlos Rodon.

[23][24] On May 14, 2021, Abreu was involved in a collision at the first base line with Kansas City Royals batter-runner Hunter Dozier during the first game of a doubleheader.

[26] On May 16, Abreu scored a walk-off run on a wild pitch by Kansas City Royals pitcher Wade Davis.

[31] Abreu obtained his 1,500th career hit on June 13, 2023, a second-inning double off Patrick Corbin of the Washington Nationals at Minute Maid Park.

As we talked through the process this week, we felt like it was time to make a change.”[42] For the season he hit .124/.167/.195 with 2 home runs and 7 RBI in 35 games and posted a −1.6 WAR, by far the lowest of his career.

Abreu's mother and the rest of his extended family remained in Cuba[45] until his parents moved to the United States in May 2014.

[48] Abreu's reputation throughout his career has been of a very positive clubhouse presence, a particularly hard worker, and a popular player throughout the league.
