Chicago ? Ron Santo’s love for the Chicago Cubs stretched from his days as a standout third baseman who one season even jumped and clicked his heels to celebrate victories to the two decades he spent unabashedly pulling for his team as a broadcaster.

As much as his passion for the Cubbies soothed their long-suffering fans, his play and work in the broadcast booth helped him, too, through tough times and serious ailments, including a bout with diabetes that cost him both legs below the knees. He called the Cubs, simply, his therapy.

Santo, who had finished his 21st season broadcasting the Cubs in September, died Thursday night in Arizona from complications of bladder cancer, according to the team and WGN Radio, his longtime employer. He was 70.

Woods extends lead at Sherwood

Thousand Oaks, Calif. — Tiger Woods is starting to look like his old self at the Chevron World Challenge.

Woods got off to a blazing start Friday and a solid putting stroke enabled him to play bogey-free in the second round for a 6-under 66 that gave him a four-shot lead going into the weekend of his final tournament this year.

Woods was at 13-under 131, his best 36-hole score this year by six shots. And the four-shot lead over U.S. Open champion Graeme McDowell had to be a refreshing change for a guy who has been at least nine shots back through 36 holes in seven tournaments this year.
