Jack Wilson shrugged off the strained right calf that kept him out of the Pirates' lineup yesterday, even though he might miss today and tomorrow, too.

"It's no big deal," he said. "Just a little tight."

It might have been worse.

Wilson's right knee jammed into the ground when he slid into second base in the seventh inning Wednesday night, but the pain went immediately to the calf. He continued playing, but still felt it upon reporting to PNC Park yesterday morning. It was checked again and diagnosed as a strained muscle in the area.

He was able to do some treadmill work before the game, then singled as a pinch-hitter in the seventh inning. Ian Snell ran for him.

"It doesn't look like an extended period," manager Jim Tracy said.

Any interruption would be unwelcome: Wilson is batting .371 since the All-Star break.

Gorzelanny going home

For any pitcher with six career starts in Major League Baseball, they are all big. Even so, for Tom Gorzelanny, the one today at Chicago's Wrigley Field will be, as he put it, "extra big."

He was born in nearby Evergreen Park, Ill., and grew up 25 minutes outside the city.

"It's a big stage for me," Gorzelanny said. "And it's a big thrill to be playing in front of so many friends and family."

He is leaving 38 tickets, "and that's not counting all the people who told me they're going to buy some."

And did he grow up a Cubs fan?

"No, I was for the White Sox. But that makes this even better because I have a chance to beat the Cubs."

Buried treasure

The Pirates, whose defensive efficiency rating of .678 is the worst in Major League Baseball, have committed one error in the past 74 innings.

Freddy Sanchez's 36 doubles rank second in the National League and have him on pace to break the franchise record for a right-handed batter, that being Adam Comorosky's 47 in 1930. The overall record is Paul Waner's 62 in 1932.

The Pirates' record in one-run games: 14-27.

Rich Thompson, an outfielder for Class AAA Indianapolis, will have season-ending surgery to repair a torn labrum in his right shoulder. Thompson, 26, was batting .280 with two home runs in 79 games.
