The Mariners appear close to hiring Manny Acta to be their third-base coach, which would add a veteran manager to the Scott Servais staff. Servais has never served as a full-time manager in the major or minor leagues.
An announcement regarding Acta could come as soon as Tuesday. If hired, the Mariners would still have openings for a first-base coach and a bullpen coach.
Acta, 46, spent parts of six seasons as the manager at Washington (2007-09) and Cleveland (2010-12) before becoming an analyst at ESPN and ESPN Desportes. His overall managerial record was 372-518.
Houston signed Acta as a 17-year-old in 1986, and he spent six seasons in their minor-league system as a first baseman and outfielder. He spent 1991 as a player/coach before switching the following season to a full-time coaching career.
Acta reached the majors in 2002 as the third-base coach at Montreal under manager Frank Robinson. Acta held that position for three years before taking a similar position in 2005 with the New York Mets under manager Willie Randolph.
Washington hired Acta as its manager in 2007.
