Joaquin Arias, a Dominican-born infielder, began his Major League Baseball career with the Texas Rangers. Signed as an amateur free agent by the New York Yankees in 2001, Arias was later traded to the Rangers in 2004 as part of the deal that sent Alex Rodriguez to New York. His debut in the major leagues came in 2006 with the Rangers, where he played intermittently over several seasons.

Arias was primarily utilized as a utility infielder during his time with the Rangers, showcasing his ability to play multiple positions, including shortstop, second base, and third base. His tenure with Texas was marked by limited playing time, as he often served as a backup to more established players. Despite this, Arias demonstrated solid defensive skills and a reliable glove, which kept him in the mix for roster spots.

In 2010, Arias was traded to the New York Mets, where he continued in a similar role. His stint with the Mets was brief, and he was soon claimed off waivers by the Kansas City Royals. However, he did not appear in a major league game for the Royals and spent the remainder of the season in the minor leagues.

Arias's career took a positive turn when he signed with the San Francisco Giants in 2011. With the Giants, he found more consistent playing time and became a valuable part of the team's infield rotation. Arias contributed to the Giants' success during their championship runs, being part of the World Series-winning teams in 2012 and 2014. His ability to step in at various infield positions provided the Giants with much-needed depth and flexibility.

During his time with the Giants, Arias was known for his steady defense and occasional offensive contributions. He played a crucial role in several key games, often coming off the bench to deliver in clutch situations. His performance in the 2012 postseason was particularly noteworthy, as he provided solid defense and timely hitting, helping the Giants secure their second World Series title in three years.

Arias remained with the Giants until 2015, after which he became a free agent. His career in Major League Baseball concluded with a brief stint in the minor leagues, as he did not return to the majors after his time with San Francisco. Throughout his career, Arias was appreciated for his professionalism and team-oriented approach, traits that endeared him to teammates and coaches alike.
