Joaquín Árias (born September 21, 1984) is a Dominican professional baseball infielder who is currently with the Arizona Diamondbacks. He has played in Major League Baseball (MLB) for the Texas Rangers, New York Mets and San Francisco Giants.
Árias was acquired by the Texas Rangers on March 23, 2004, completing a trade made 36 days earlier on February 16 that sent Alex Rodriguez to the New York Yankees for Alfonso Soriano. Among five Yankees prospects offered to the Rangers, Árias was selected over Robinson Canó because he was a more polished defender and two years younger. Árias made his Major League debut with the Rangers on September 13, 2006, drawing a walk.
Árias was designated for assignment on August 24, 2010 and traded to the New York Mets on August 31 for Jeff Francoeur.
On November 4, 2010, Árias was claimed off waivers by the Kansas City Royals, but the Royals designated Árias for assignment on December 19 to make room on the 40-man roster for the prospects acquired in the Zack Greinke trade.
Joaquín Arias Blanco (born 12 November 1914, date of death unknown) was a Cuban footballer.
He represented Cuba at the 1938 FIFA World Cup in France. He played three matches.
