Sanchez's dad, Sirgfredo, watched nervously from the stands, bouncing and biting his nails, then scurried down to the dugout to be among the first to congratulate the pitcher.
"Right now I'm just going to go home and hang out with my dad," Sanchez said. "I was pumped that he was here watching the game."
Sanchez almost lost his no-hit bid in the ninth, but Gold Glove center fielder Aaron Rowand saved the gem with a leaping grab at the center-field fence to rob pinch-hitter Edgar Gonzalez for the second out.
"I was going to go up and over and land on the other side of the fence if I had to, to try to make the catch," Rowand said.
The 26-year-old Sanchez (3-8) returned to the rotation after a nearly three-week demotion to the bullpen
- and only got the call because 303-game winner Randy Johnson went on the disabled list this week with a shoulder injury.
With his father and a friend cheering from the stands, Sanchez threw a called third strike past Everth Cabrera to finish his first career complete game. Sanchez walked toward the plate and thrust his arms in the air as catcher Eli Whiteside rushed in for a big hug and the Giants poured out of their dugout.
Also offering their congratulations were Johnson, the last major leaguer to throw a perfect game, and Giants pitching coach Dave Righetti, who tossed a no-hitter for the New York Yankees on July 4, 1983.
Sanchez's father is visiting from Puerto Rico and arrived in San Francisco on Thursday night. When the pitcher came off the field, the two shared a long embrace before Sanchez jogged back onto the field and tipped his cap to the cheering crowd.
"This is a gift for him," said Sanchez, who struck out a career-high 11. "I feel awesome."
It was the Giants' 13th no-hitter and first since John Montefusco did it on Sept. 29, 1976, at Atlanta. Their last one in San Francisco came when Ed Halicki beat the New York Mets in the second game of a doubleheader on Aug. 24, 1975.
The Padres were no-hit for the seventh time and first since Bud Smith blanked them 4-0 for St. Louis on Sept. 3, 2001.
Sanchez did it on 110 pitches, 77 for strikes. After the final one, Whiteside came rushing with a hug, followed moments later by all their teammates.
Sanchez, who won for the first time since May 25, had a five-start winless stretch this season in which he went 0-4. He told The Associated Press two days earlier that he hadn't lost his confidence in his ability to pitch and be a starter in the major leagues
- and manager Bruce Bochy hadn't lost faith, either.
"They gave me a second chance. You see what happened tonight," Sanchez said.
Sanchez pitched the first no-hitter in the majors since Carlos Zambrano for the Chicago Cubs against the Houston Astros in Milwaukee on Sept. 14, 2008. That game was relocated from Houston to Miller Park because of Hurricane Ike.
Sanchez's father and friend stood nervously - with the rest of the crowd of 30,298 at AT&T Park on a cool night in the Bay Area
- and his dad couldn't look at the end. But Sanchez's dad quickly got down to the dugout to congratulate a pitcher who made his 51st major league start the most special of his career after months of struggles.
"Felicidades!" - congratulations - fans yelled in the tunnel outside the San Francisco clubhouse as Sanchez signed autographs.
