Cubs left fielder Alfonso Soriano still has enough pain every day that he might wind up with a second surgery on his left knee depending on what it feels like the rest of the season, he said Saturday.

But Soriano, 36, refuses to sit, refuses to complain and refuses to let it alter the way he goes after balls during a season in which he's experiencing a defensive rebirth.

Kerry Wood singled out Soriano for that toughness as he looked back on the trials and travails of his own career.

''I've got respect for guys that have played this game for a long time because it's not easy to do,'' Wood said. ''I have tremendous respect for what Soriano's doing out there in left field for us this year and the way he has worked and what he has put in knowing what his body has gone through.''
