"Ron Washington informed us today that he has chosen to resign as Rangers manager in order to turn his full attention to addressing an off-the-field personal matter. Out of respect for Ron's privacy, the Rangers will leave any comment on the details to him.
"While we are disappointed, we accept Ron's decision and are grateful for his many contributions to the Rangers organization over the last eight years. This has certainly been a difficult season for our major league club in terms of on-field performance, but we were looking forward to moving ahead with Ron as our manager in 2015.
"Ron has guided the Rangers franchise to more victories than any manager in club history, including four straight 90-win seasons, three playoff appearances, and back-to-back American League championships. He has left his mark as a teacher, motivator, and leader on this organization. We wish Ron the best as he deals with this matter."
Bench coach Tim Bogar has been appointed interim manager for the remainder of the 2014 season. Bogar, who has spent the last 11 seasons as a major league coach and minor league manager, is in his first season on the Texas staff.
Washington was appointed as the Texas Rangers 17th full-time manager on November 6, 2006. His record at the helm is 664-611, and he is the franchise's all-time leader in regular season wins and games managed (1275). He has also compiled an 18-16 record over post-season appearances in 2010 (A.L. Champs), 2011 (A.L. Champs), and 2012 (A.L. Wild Card).
