BOSTON — David Ortiz hit his 51st and 52nd homers Thursday, breaking the Red Sox record for most homers in a season of 50 set in 1938 by Jimmie Foxx.

Ortiz connected on the first pitch he saw in the first inning from Johan Santana, sending it over the Boston bullpen in right-center field. The lefty designated hitter hit the ball even further in the seventh, belting it over the center-field wall on a full count against Matt Guerrier.

The 52 homers ties Ortiz for 12th most in AL history.

SAN FRANCISCO — Two San Francisco Chronicle reporters were ordered jailed Thursday, pending an appeal, for refusing to testify about who leaked them secret grand jury testimony from Barry Bonds and other elite athletes.Lance Williams and Mark Fainaru-Wada published a series of articles and a book based partly on the leaked transcripts of the testimony of Bonds, Jason Giambi and others before a grand jury investigating the Bay Area Laboratory Co-Operative.Federal prosecutors asked U.S. District Judge Jeffrey White to send the reporters to prison for the full term of the grand jury investigating the leak, or until they agree to testify. Both sides agreed to stay the ruling pending an appeal to the 9th U.S. Circuit Court of Appeals.Williams and Fainaru-Wada have said repeatedly they would go to jail rather than comply with the grand jury's subpoena and reveal their source or sources.

BALTIMORE — Nearly a thousand disgruntled Orioles fans walked out of Baltimore's game against Detroit en masse Thursday, culminating a demonstration aimed at team owner Peter Angelos.A majority of the protesters wore black T-shirts that read "FREE THE BIRDS," and many carried signs that had "For Pete's Sake" on one side and "Free the Birds" on the other.They filled parts of six sections in the upper deck, then walked out in the middle of the fourth inning at precisely 5:08 p.m. — in honor of former Orioles stars Brooks Robinson (No. 5) and Cal Ripken (No. 8).Baltimore is in the midst of its club-record ninth consecutive losing season, all of them under the leadership of Angelos, who gained control of the franchise in 1993.
