"I've done everything but manage," Simmons said. "This is my third year as the bench coach [second with San Diego] and after three years, either you do it [manage] or forget about it."
Simmons, who will turn 61 on Aug. 9, said Monday that he's interested in becoming a Major League manager. A report on AOL Fanhouse recently said the Marlins might want to interview him after the season.
Simmons, who was an eight-time All-Star catcher, wouldn't comment on what could be a potential opening with the Marlins, saying he'll let the regular season finish before he pays to much attention to where vacancies might be.
"If you're serious about managing ... it doesn't matter where you do it," Simmons said.
San Diego general manager Jed Hoyer said, on the heels of the three-year extension manager Bud Black received Monday, that the rest of the coaching staff will be dealt with following the season.
Hitting coach Randy Ready has twice been interviewed for managerial openings -- first in Seattle and then in Houston. Now Simmons might find himself a candidate to manage.
"When teams win, this kind of speculation begins," Simmons said.
