Clemens pitches in relief

Roger Clemens pitched in relief for the New York Yankees on Sunday in San Francisco, his first regular-season appearance as a reliever since he was a rookie with the Red Sox 23 years ago.

Clemens, who lost to the Colorado Rockies on Thursday and missed a chance for his 350th win, walked Barry Bonds and yielded Nate Schierholtz’s sacrifice fly in the seventh inning against the San Francisco Giants.

The 44-year-old Clemens made his only other regular-season relief appearance in his 13th career game, when he allowed two hits over two innings in Oakland on July 18, 1984.

Clemens volunteered to fill in for the Yankees’ weary bullpen after Saturday’s 13-inning loss to the Giants.

He ended the longest stretch between regular-season relief appearances in major league history at 22 years, 341 days, according to the Elias Sports Bureau. Steve Carlton went 15 years, 343 days between 1971 and 1987.

Morneau still in hospital

Minnesota Twins slugger Justin Morneau remained in a hospital in Miami awaiting test results on his bruised right lung, and he didn’t accompany the team on its flight home following a weekend series against the Florida Marlins.

The 2006 American League MVP was hurt Friday in a collision with Marlins catcher Miguel Olivo.

“He’ll probably end up flying back (today),” Twins manager Ron Gardenhire said. “He says he’s feeling fine.”
