A high school classmate of Minnesota Twins pitcher Carl Pavano threatened to reveal an alleged homosexual relationship they had and to write a book about it unless Pavano apologized to him and bought him a navy Range Rover SUV with tan leather, according to a search warrant affidavit filed by police in Hartford, Conn.

Police in Pavano’s hometown of Southington, about 18 miles southwest of Hartford, said in the affidavit that they began investigating the allegations after Pavano’s sister, Michelle DeGennaro, complained in December that she had received several troublesome Facebook messages from the classmate, Christian Bedard. DeGennaro told police that Bedard made up a bogus story about having a relationship with her brother in an attempt to extort her family.

Officers executed the search warrant at Bedard’s home on March 21 and seized items, but wouldn’t say what they were. Bedard said on his Facebook page that police took his laptop computer, material relating to his relationship with Pavano and the book he was writing. Bedard hasn’t been charged.

Giants aim to lock up Cain

The San Francisco Giants are committed to keeping All-Star right-hander Matt Cain in their talented rotation beyond 2012, and CEO and president Larry Baer said Thursday that serious conversations are ongoing with the pitcher’s representatives.

“We’re earnestly working with his agents,” Baer said, speaking after a media open house at AT&T Park to unveil the ballpark’s changes, promotions and new food items for this year. “It wouldn’t be good to forecast it. All I know is there are discussions, and the discussions have been continuing.”

The 27-year-old Cain went 12-11 last season with a 2.88 ERA, reaching 200 innings for the fifth consecutive season. He also didn’t allow an earned run during the entire 2010 postseason.

Phillies keep Pierre

Juan Pierre made the Philadelphia Phillies’ Opening Day roster. Philadelphia selected the contract of the 34-year-old outfielder from Triple-A Lehigh Valley on Thursday. Pierre gets an $800,000 one-year contract with incentives.

Cubs send down Wells

Right-hander Randy Wells was among nine players sent to the minors by the Chicago Cubs. Wells, a 12-game winner in 2009, was 7-6 with a 4.99 ERA last season when he was slowed by an early injury to his forearm. His demotion means Jeff Samardzija and Chris Volstad have made the starting rotation along with Ryan Dempster, Matt Garza and Paul Maholm.

Also sent down was lefty Travis Wood, who struggled this spring after being acquired from Cincinnati.

Yankees have top value

The New York Yankees are worth a Major League Baseball-high $2.85 billion after a group led by basketball hall of fame player Magic Johnson bought the Los Angeles Dodgers in a $2.3 billion transaction, according to an estimate by a media analyst. Tony Wible, a Philadelphia-based analyst who covers media companies for Janney Montgomery Scott LLC, said his valuation was based on the number of television households in the team’s designated market area, or DMA.
