BOSTON - Clay Buchholz threw a no-hitter in his second major league start, just hours after being called up by the Boston Red Sox.

The lanky Texan baffled Baltimore with an assortment of curves, changeups and fastballs in the Red Sox's 10-0 victory Saturday night. He struck out nine, walked three and hit one batter before the 371st straight sellout crowd at Fenway Park.

The crowd stood through the entire ninth inning, cheering every pitch and taking pictures of the young righty in his windup and as he paced around the mound between pitches. A groan rose from the stands 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 2-1 when the batter fouled one off with a check swing. The crowd grew even louder, the flashes were constant, and Buchholz threw a 77 mph curveball that Markakis watched go by.

Home 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.

Buchholz became the 17th rookie to throw a no-hitter. The last one to do it was Florida's Anibal Sanchez last Sept. 6.
