MILWAUKEE — It's not the sort of record that is on the tip of baseball fans' tongues like a 56-game hitting streak or 762 career home runs, but the National League mark Rickie Weeks tied Friday might be the best indication of the value he has to the Milwaukee Brewers this season.

When Weeks scored the Brewers' first run in the 13-4 Opening Day victory over the San Francisco Giants, it marked the 17th straight game he has scored a run, tying the NL mark shared by Rogers Hornsby (1921 with St. Louis) and Ted Kluszewski (1954 with Cincinnati) and leaving him one game shy of tying the major league record shared by Red Rolfe (1939 with New York) and Kenny Lofton (2000 with Cleveland).

Weeks has ignited the offense through four games, scoring seven of the team's 28 runs. Three of those runs came Friday.

"It feels good," Weeks said of the NL record. "But that's not the point. We're just trying to win games right now."

But that's where those two points intersect.

Weeks has reached base nine times in 20 plate appearances, a .450 on-base percentage. His on-base to run-scoring quotient is even more impressive.

"He's been getting on," manager Ned Yost said. "He's picked up right where he finished last year. We always knew Rickie would be an offensive force for us. He's starting to become a complete player."

Gwynn still hurting

Tony Gwynn, who injured his left hamstring in Thursday's loss in Chicago, was not scheduled to be in the starting lineup Friday because the Giants were using left-hander Jonathan Sanchez.

But it's unlikely he would have been able to play if the Giants had started a right-hander.

Gwynn did not participate in batting practice but is holding out hope that his leg will show enough improvement to get him back in the lineup Saturday against Giants right-hander Kevin Correia.

"But if it doesn't feel any better," he said, "I don't know if I'll be able to go (Saturday)."

The timing of the injury is especially unfortunate for Gwynn, the team's primary center fielder until Mike Cameron returns from his 25-game suspension for testing positive for a banned stimulant last fall.

Gwynn knocked in the winning run in Monday's opener against the Cubs and is hitting .571.

Gabe Kapler started in center Friday, his second start of the season, and contributed run-scoring singles in the Brewers' five-run fifth and five-run sixth. Kapler had three hits and also scored twice.

Yost has two options if Gwynn is unable to play today. He could move right fielder Corey Hart to center and play left-handed hitting Gabe Gross in right, or stick with Kapler.
