The Mariners reinstated utilityman Willie Bloomquist from the 60-day disabled list in a move that boosted their 40-man roster to 34 players.
Bloomquist, 36, underwent season-ending surgery Aug. 9 on his right knee after suffering a micro-fracture July 23 while running out a ground ball. He batted .278 in 47 games prior to the injury.
The move was expected. All players on the 60-day disabled list must be returned to the 40-man roster within five days after the conclusion of the World Series.
Bloomquist is under contract through next season after returning Dec. 9, 2013 to the Mariners as a free agent. He agreed to a two-year deal for $5.8 million that includes $3 million for 2015.
