"There's a chance you could see him in the field," Padres manager Bud Black said prior to Sunday's game.
Quentin, who had arthroscopic surgery on his right knee March 19, played the second game of a Minor League rehabilitation stint Saturday with Class A Lake Elsinore. He went 1-for-3 after getting three hits, including a home run, on Friday.
Black said Quentin wasn't scheduled to play Sunday for the Storm and that he was looking into flights that would get Quentin to Chicago in time for the start of the three-game series Monday at Wrigley Field.
That game starts at 11:20 a.m. PT, meaning Quentin would have to fly on Sunday.
This was Quentin's second rehab stint, as he had a setback the week of May 7 when he experienced some soreness in his knee when he got into his hitting stance. He returned to San Diego for treatment that apparently worked wonders on the knee.
"His second go-around in rehab went markedly better than the first," Black said. "He's confident where his knee is. He's doing well."
What could Quentin's bat do for the Padres? The team has scored one run in its last two games and San Diego has been shut out twice already on this road trip.
"It will make the lineup look different," Black said of Quentin's inclusion.
The Padres have been deferring to Quentin about when he would be ready to join the team. That time seems to be now.
"We left it up to him when to pull the trigger when he's ready," Black said.
The Padres traded for Quentin on December 31, sending two Minor League pitchers to the White Sox for him. Quentin started to experience discomfort in his knee the first week of Spring Training. He later had surgery to repair some meniscus tearing and remove loose particles.
