Ross was still in some pain Friday and manager Bud Black said it's not certain the right-hander will make his next start Tuesday against the Brewers at Petco Park.
"He wants to pitch but we're going to monitor it," said Black. "I won't say that it's definite that he'll start."
This was the second time Ross suffered a subluxation, which is a partial dislocation of the shoulder joint. He was attended to at first base briefly in the third inning of the Padres' 7-2 victory. He remained in the game and nearly got his first Padres victory, going 4 2/3 innings.
"I went from being really happy I made contact to being in agonizing pain. I kind of knew what it was. I'll be all right," Ross said. "I've experienced it before ... but never swinging a baseball bat. When it happens, it hurts really bad and after that it's sore but takes care of itself."
Ross distinctly remembers the first time he suffered a similar injury, when he was playing golf. He was asked if the shot was at least good.
"No," he said, smiling. "None of my shots are good."
