Gardner pitched a three-hitter and J.T. Snow hit a grand slam and drove in five runs, giving San Francisco a 7-0 victory over Texas.
Gardner (7-3) gave up a ground-ball single to Tom Goodwin leading off the fourth. He allowed nothing else until Kevin Elster's two-out single in the eighth, walking none and striking out five.
In three interleague starts against the Rangers, Gardner is 2-0 with a 1.50 ERA.
"When you bring them to our park, it equalizes things a little bit," said Gardner, who pitched the Giants past the Rangers 4-3 at Texas last June 12.
"But I think every pitcher should still be intimidated by them. Great teams demand that you should bear down," he said.
Texas first baseman Will Clark was impressed.
"If you shut down this team on three hits, you're doing something," Clark said.
Snow, who hit three grand slams while playing for the California Angels, hit his first NL slam in the second inning off Aaron Sele (11-5). The home run was Snow's seventh of the season and 100th of his career.
"After he hit that grand slam, that's the flattest I've seen this team in four years," Texas manager Johnny Oates said.
The Giants took a 3-0 lead in the first on a two-run single by Charlie Hayes and sacrifice fly by Snow.
Sele walked Hayes and Darryl Hamilton and gave up a one-out single in the second to load the bases. Snow sliced an opposite-field home run over the fence in left for a 7-0 lead.
Sele missed out on his bid to become the AL's first 12-game winner. He lasted five innings and gave up six hits, walking four and striking out seven. In his last seven starts, Sele is 3-3 with a 7.52 ERA.
"I'm fine," Sele said. "They just got some hits, and we didn't. It's tough to beat a three-hitter."
Oates was more to the point.
"Here's a guy who's got 11 wins and is among the leaders in the league," Oates said. "I find no fault with Aaron Sele's pitching."
Mark McLemore was the only other Ranger to get on base, reaching on an error by shortstop Rey Sanchez in the seventh.
