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

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

“I sort of tried to zone everything out, but it was sort of hard with 40,000 people screaming,” said the Lumberton native and former standout at Angelina College. “I’m in a blur right now.”

The crowd stood through the entire ninth inning, cheering every pitch and taking as Buchholz 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 1-2 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.

Buchholz (2-0) became the 17th rookie to throw a no-hitter. The last one to do it was Florida’s Anibal Sanchez against Arizona last Sept. 6.
