Red Sox pitcher Clay Buchholz points toward a pop-up. Buchholz no-hit the Baltimore Orioles on Saturday, just his second major-league start.

It was the 17th no-hitter in Red Sox history, and the first since April 27, 2002, when Derek Lowe beat Tampa Bay, also 10-0. The Orioles were no-hit for the first time since April 4, 2001, by Boston’s Hideo Nomo.

“I’ve been a part of some great nights at Fenway,” said Baltimore’s Kevin Millar, a member of the 2004 championship team, “but this stunk. It really stunk.”

The Red Sox broke a four-game losing streak and maintained their five-game lead in the AL East over the New York Yankees, who beat Tampa Bay.

Boston scored a run in the second off Garrett Olson (1-3) and took a 4-0 lead in the fourth on David Ortiz’s three-run double. The Red Sox made it 8-0 in the eighth on Lowell’s RBI double and Kevin Youkilis’ three-run homer.

“Early in the game we were trying to win,” Tejada said. “But after they got the big lead we were trying to break up the no-hitter.”

Buchholz made his first major league start Aug. 17 when he was called up from Pawtucket to pitch the opener of a day-night doubleheader in Boston against the Angels. He allowed three earned runs in six innings and got the win in the 8-4 victory.

Buchholz drew his second start when the Red Sox were forced to shuffle their rotation after Tim Wakefield was scratched from Friday’s game with a sore back. Buchholz found out in the middle of Pawtucket’s game, gathered his things and headed to Boston.

“Now that I’m here, I feel like nothing can go wrong,” Buchholz said. “I’ll try to keep an even keel and remember it’s not that easy all the time.”

The Red Sox drafted Buchholz, who turned down offers to play wide receiver at Texas, Notre Dame, Purdue and Texas A&M, with a pick obtained as compensation when they lost free agent Pedro Martinez to the New York Mets.

Buchholz was chosen 42nd in the 2005 draft out of Angelina Junior College in Texas, where he went 12-1 with a 1.05 ERA that year.

He started this season with Double-A Portland, where he was 7-2 and led the Eastern League with a 1.77 ERA and 116 strikeouts with one loss in his last 15 outings. He was promoted July 12 to Pawtucket, going 1-3 with a 3.96 ERA in eight starts.

Notes: Ortiz reached base four times with a double and three walks. ... The Orioles were no-hit for the 14th time in franchise history.
