Teixeira knocked a two-run homer off John Danks at U.S. Cellular Field from the right side in the third inning, then hit a solo shot from the left side off Jason Frasor in the seventh.
Growing up in Baltimore, Teixeira idolized switch-hitting Hall of Famer Eddie Murray. On this night, he passed Murray and former Yankee Chili Davis, each of whom had 11 such games.
"There's a lot of failure in this game, there's no doubt," Teixeira said. "When you can put your name in the record books to something like this -- being a switch-hitter is very tough, and this was a nice night for me."
Teixeira has switch-hit homers seven times since joining the Yankees in 2009. He did it three times during his 4 1/2 seasons with Texas and twice during his two half-seasons with Atlanta.
Here is a list of games in which Teixeira homered from each side of the plate:
July 4, 2004, vs. Astros at Minute Maid Park
Sept. 18, 2005, vs. Mariners at Rangers Ballpark
July 13, 2006, vs. Orioles at at Camden Yards
June 22, 2008, vs. Mariners at Turner Field
July 20, 2008, vs. Nationals at Turner Field
May 4, 2009, vs. Red Sox at Yankee Stadium
May 18, 2009, vs. Twins at Yankee Stadium
Sept. 19, 2009, vs. Mariners at Safeco Field
May 8, 2010, vs. Red Sox at Fenway Park
July 9, 2010, vs. Mariners at Safeco Field
June 15, 2011, vs. Rangers at Yankee Stadium
Aug. 2, 2011, vs. White Sox at U.S. Cellular Field
Now with a team-leading 31 homers, Teixeira has notched eight straight 30-plus-homer seasons, including his first three as a member of the Yankees.
Teixeira, one behind Jose Bautista of the Blue Jays for the Major League lead in homers, is the fourth player in franchise history to go deep at least 30 times in each of his first three seasons with the Yanks. The others are Babe Ruth, Roger Maris and Alex Rodriguez.
With a 3-for-4 night, the Yankees' first baseman has 10 hits in his past four games.
"To think that he holds the record already and he's still fairly a young man, you're talking about some great hitters when you talk about Eddie Murray and Hall of Famers," Yankees manager Joe Girardi said. "Tex is on a great streak right now, and we need him."
