About Don Wakamatsu

Born 1963. Don Wakamatsu is an American baseball player, baseball manager and baseball coach.

Wilbur Donald Wakamatsu (born February 22, 1963) is an American former professional baseball player, scout, coach, and manager. Wakamatsu was drafted in the 11th round of the 1985 Major League Baseball draft by the Cincinnati Reds. He played as a catcher in Major League Baseball for the Chicago White Sox. He served as the bench coach of the Texas Rangers from 2018 through 2021. He was hired as bench coach of the Kansas City Royals for the 2014 season. He was the manager of the Seattle Mariners for the 2009 season, as well as the majority of the 2010 season. He was the Toronto Blue Jays' bench coach for 2011 and 2012, after which he was replaced by DeMarlo Hale. During the 2013 season he worked as a scout for the New York Yankees in the Dallas/Fort Worth area. He is currently the first-ever executive vice president of baseball operations with the Oakland Ballers.

Playing career

High school and collegiate Wakamatsu was a three-sport star at the Bay Area's Hayward High School in California, and ultimately chose baseball over football due to his lack of size. He and former Oakland Raiders head coach Jack Del Rio were baseball and football teammates.

He was also an All-Pac-10 catcher during his last three years at Arizona State University, where he was a teammate of Barry Bonds and Alvin Davis. He was drafted by the New York Yankees as the last pick of the 1984 Major League Baseball draft, but decided to return to ASU.

Professional

Wakamatsu was drafted in the 11th round of the 1985 Major League Baseball draft by the Cincinnati Reds. He reached the Double-A level before the Reds released him before the 1989 season.

Shortly after the Reds released him, he signed with the Chicago White Sox, who assigned him to the Double-A Birmingham Barons. He spent 1990 and most of 1991 with the Triple-A Vancouver Canadians before getting his only call to the big leagues in May 1991. Wakamatsu played 18 games in the majors as a backup catcher for the White Sox in 1991, after leading the High Desert Mavericks to the playoffs.

He spent 2000 managing the Erie SeaWolves, the Anaheim Angels' Double-A affiliate, and then the next two seasons as a roving catching instructor in the Angels organization.

Major leagues From 2003 to 2006, Wakamatsu was the Texas Rangers' bench coach. During the 2006 season, he served as manager for two games while Buck Showalter was in the hospital with an irregular heartbeat brought about due to dehydration, and in 2007, took the third base coach job when Ron Washington took over as manager. He spent 2008 as the bench coach of the Oakland Athletics.

On November 19, 2008, Wakamatsu was named the manager of the Seattle Mariners, replacing interim manager Jim Riggleman, and becoming the first Asian-American manager in the majors.

On April 6, 2009, Wakamatsu won his managerial debut as the Mariners beat the Minnesota Twins 6–1 on Opening Day.

Later in the season, Wakamatsu was officially selected as a coach under Tampa Bay Rays manager Joe Maddon for the 2009 MLB All-Star Game in St. Louis along with Kansas City Royals manager Trey Hillman on June 17, 2009.

Fred Claire, former baseball executive and current writer for MLB.com, stated that Wakamatsu and his staff, composed of bench coach Ty Van Burkleo, pitching coach Rick Adair, hitting coach Alan Cockrell, first base coach Lee Tinsley, bullpen coach John Wetteland and performance coach Steve Hecht, deserved credit for a 24-game improvement. Claire wrote this about Wakamatsu:

On May 20, 2010, during a game against the Toronto Blue Jays, Wakamatsu received his first career ejection. As of June 12, 2010, he had a career total of two ejections.

On August 9, 2010, amidst one of the worst seasons in team history, Wakamatsu was fired as Mariners manager.

On November 8, 2010, Wakamatsu was announced as the new bench coach for the Toronto Blue Jays, under new manager John Farrell.

On October 25, 2013, Wakamatsu was announced as the new bench coach for the Kansas City Royals.

On April 19, 2015, Wakamatsu was one of five Royals (also pitching coach Dave Eiland, manager Ned Yost, pitcher Kelvin Herrera and shortstop Alcides Escobar) to be ejected in a game against the Oakland Athletics. Two games prior, Escobar had been injured following an attempt by A's third baseman Brett Lawrie to break up a double play. Considering the slide a dirty one, Royals pitcher Yordano Ventura hit Lawrie in the elbow the following game and was immediately ejected. In the series finale, A's pitcher Scott Kazmir hit Lorenzo Cain in the foot and warnings were given. Yost and Eiland were immediately ejected for arguing. Later in the 8th inning, Kelvin Herrera threw a 100 mph fastball behind Lawrie and a trio of ejections followed (Herrera, Wakamatsu and Escobar). The Royals would end up winning the game 4–2 despite the ejections. Wakamatsu was actually ejected twice, as when a warning has been issued, the pitcher and manager are automatically ejected. Wakamatsu was the acting manager. This was the cause of his first ejection, the second being him arguing with the home plate umpire.

The Rangers hired Wakamatsu as their bench coach before the 2018 season. When manager Jeff Banister was fired in September 2018, Wakamatsu took over as interim manager. He finished with a record of three wins and seven losses. Wakamatsu was let go by Texas following the 2021 season.

Luke was drafted in the 20th round of the 2015 MLB draft.

Born to a Japanese American ironworker father and an Irish American dental assistant he is fourth generation Japanese American and the first Asian-American manager in Major League Baseball history.
