Major League Baseball's official Twitter account broke the news after Teixeira's solo shot off Carlos Villanueva in the top of the eighth inning:
Teixeira's achievement was a welcome bright spot amid what was otherwise a forgettable day to compound a disappointing 2016 campaign. The three-time All-Star raised his average to .188 with his sixth homer of the year after striking out in each of his three prior at-bats.
Carlos Beltran, Teixeira's teammate, is another switch-hitter who has reached the 400-homer mark this year, which at this juncture has more utility for future trivia than the club's circumstances.
Teixeira's power from both sides of the plate throughout his MLB career has been impressive in spite of his slumping form this year. Sunday's homer was more of a celebration of Teixeira's legacy, which has paralleled how the Yankees' collective fortune has been this season.
The Bronx Bombers entered Sunday's contest in the bottom third of the majors in batting average, runs scored and slugging percentage, thus not living up to their previously earned moniker.
It's going to take a strong effort for Teixeira to rise above the Mendoza Line—and an even stronger one for the Yankees to band together and make a charge after the impending All-Star break. At 39-41 entering Sunday's game, New York was fourth in the American League East and well outside the AL playoff picture.
For the proud franchise rife with championship trophies, accomplished players like Teixeira need to emulate their elite form of yesteryear for the Yankees to salvage their 2016 campaign.
