Boston ? Clay Buchholz threw a no-hitter in his second major-league start, just hours after the Boston Red Sox promoted him from the minors Saturday night.

The 23-year-old righty became the first Red Sox rookie to throw a no-no, baffling Baltimore with an assortment of curves, changeups and fastballs in a 10-0 victory.

“I tried to zone everything out, but it was sort of hard with 40,000 people screaming,” he said. “I’m in a blur right now.”

A groan rose from the stands in the ninth when Corey Patterson hit a line drive to center with one out, but Coco Crisp easily moved over to catch it.

Buchholz started Nick Markakis with a ball, then went ahead 1-2 when the batter fouled one off with a check swing. Buchholz threw a 77 mph curveball that Markakis watched go by for strike three.

Plate umpire Joe West hesitated, but catcher Jason Varitek rose from his crouch to run to the mound. The rest of the Red Sox soon joined him there.

Yankees 9, Devil Rays 6

New York – Alex Rodriguez homered and drove in four runs to back Ian Kennedy’s stellar major-league debut.

Both confiscated bats were sent to the commissioner’s office for inspection. Kennedy allowed one earned run in seven innings.

Blue Jays 2, Mariners 1

Toronto – Troy Glaus singled home the go-ahead run in the eighth inning, and Toronto handed Seattle its season-high eighth straight loss.

Dustin McGowan (9-8) won for the first time in five starts. He allowed one run and six hits in eight innings, with a walk and three strikeouts.

Tigers 6, Athletics 1

Oakland, Calif. – Justin Verlander struck out 10 and outpitched Dan Haren in their third matchup of 2007, and Curtis Granderson homered, doubled and scored three runs.
