SARASOTA, Fla. (AP) _ Third baseman Aaron Boone, son of Cincinnati Reds manager Bob Boone, signed a one-year contract with the team Monday.

The signing leaves five unsigned players on the Reds. They are pitchers Rob Bell, Seth Etherton, Jim Brower and Hector Mercado and catcher Jason LaRue.

Aaron Boone had reconstructive surgery on his left knee last August to repair a torn anterior cruciate ligament. He has been taking infield practice and has said he expects to be ready to go by the season opener April 2 against Atlanta.

The Reds plan to use him in exhibition games by mid-March.

Boone hit .285 last year in 84 games with 12 homers and 43 runs batted in.
