Robinson Cano has been working out at third base at his complex in the Dominican Republic.
Cano can return from his 80-game suspension for violating major league baseball's joint drug agreement on Aug. 14.
The Seattle Mariners have talked about using Cano as an everyday player between first base, designated hitter and second base.
"Talking with Robbie, he just wants to help any way he can," Scott Servais said. "If that means giving Kyle (Seager) a day off at third, or helping at first base, playing a game at second base, he's going to play wherever we need him to play. He wants to be prepared as well as he can to handle those spots."
Cano played 16 games at third base in parts of three minor league seasons, but hasn't since one game with Triple-A Columbus in 2005 and four games there with Double-A Trenton in 2004.
