Someone apparently forgot to tell Marquis, who has pushed on as if he will pitch again this season, even though the odds of that happening are miniscule.
On Thursday, Marquis threw a bullpen session, a testament to him keeping his arm in shape during his stint on the disabled list.
"He loves baseball," Padres manager Bud Black said. "He loves to throw. When he broke his hand, he wanted to keep throwing. He wanted his body clock to know he was pitching in September. I admire that.
"He's been throwing hard bullpens and going through it."
Marquis, 34, was 6-7 with a 4.04 ERA in 15 starts with the Padres after signing a Minor League contract in May after he was designated for assignment by the Twins. He will be a free agent this offseason.
