"I'm sure he could [play second in an emergency]," manager Lloyd McClendon said. "It doesn't hurt to play the field, but his biggest challenge is running. It's not swinging the bat or fielding, it's running.
"The ideal," McClendon said with a grin, "would be to just hit it out of the ballpark and jog around the bases."
The Mariners will let rookie Ketel Marte handle the second-base duties until Cano is full-go. McClendon said the plan is for Cano to return to the field on Monday or Tuesday against the Rockies.
