Einar Diaz is born in Chiriqui, Panama.

Diaz, who would spend eleven seasons in the Major Leagues, began that path after signing as an amateur free agent with the Cleveland Indians in 1990. He debuted as a September call up in 1996 and appeared in four games that season. He made five appearances in 1997 and 17 more in 1998 before becoming a regular backstop for the club in 1999, playing in 119 games and batting .281.

He maintained a role behind the plate for the Tribe through the 2002 season. Following the season, he was dealt with pitcher Ryan Drese to the Texas Rangers for pitcher Aaron Myette and first baseman Travis Hafner, with the latter paying far more obvious dividends in what would be viewed long-term as a substantial steal for the Indians organization.

Diaz played one season in Texas, appearing in 101 games, before he was dealt prior to the 2004 season to the Montreal Expos. He spent 2005 in St. Louis Cardinals before re-signing with the Indians for the 2006 season. He spent the first five months of that season at Triple-A Buffalo before he was purchased by the Los Angeles Dodgers. He worked in three games for the Dodgers, the final appearances of his big league career, before spending the first half of the 2007 playing in the Pittsburgh Pirates’ farm system.

Following his career, he managed two seasons in the minors for the Baltimore Orioles and worked as the club’s assistant hitting coach for three seasons from 2013 to 2015 before assisting the entire coaching staff. He has also served as a coach with Gigantes del Cibao of the Dominican Winter League following the 2016 season.
