Marquis did need a coach to return the catcher's throws, and his chances of returning before the end of the season remain slim. Marquis went 6-7 with a 4.04 ERA in 15 starts for San Diego, which signed him as a free agent in May.
"He wants to keep throwing, which is great," Black said. "He wants to keep his body going through September. He feels good but still needs to get clearance on catching a baseball."
And with only 15 games remaining after Sunday, it's a long shot that Marquis will appear in games this season, though Black wasn't willing to close that door.
Marquis will be a free agent after this season and the Padres will likely add one or two pitchers in the off-season. That should prevent them from getting in the bind they were in this season, when they went through 15 different starting pitchers due to a slew of injuries.
