"A couple of days back, the pain was significant," said Quentin, standing in the Angel Stadium visitors' clubhouse with his shoulder wrapped. "Obviously, it was a very fresh injury then. The pain has gone away as far as standing and just walking with it.
"We'll see if the pain can keep going away and get the inflammation down and the range of motion comes back. Those will all be steps in the right direction."
As far as baseball activities, Quentin planned to get a workout in Tuesday as much as he could without putting too much strain on the AC joint and not inflame it. His goal was to do some leg work and take one-handed swings with his right arm just to get somewhat of a feel.
"That's about it until we get more information as it progresses," said Quentin, who injured the shoulder during the first inning of Saturday's victory over the Rangers, making a diving catch on Craig Gentry's fly ball.
"He has made a lot of progress," White Sox manager Ozzie Guillen said. "I expect or hope he can play the first game when we're back in Seattle [starting Friday]. We have a game here and a day off. Hopefully, that helps him."
Quentin explained that the right arm for a right-handed hitter supplies the power of the swing, but the left arm is equally important as a guide for accuracy. So, he might be slightly hampered when coming back with some soreness.
It looked like that level of pain or any potential problem with his swing wasn't enough to put Quentin on the disabled list, even if he couldn't play against the Mariners.
"They haven't told me anything about that," Quentin said of the DL. "Right now, we are monitoring the progress."
"All of a sudden, if he can't be ready in five days, why should we wait for 15 days?" Guillen said of Quentin, who is second on the White Sox in homers and RBIs. "I don't think it's worth it to make that move unless it's something very drastic about, wow, he can't tolerate the pain anymore."
