On April 23, against the Angels, Teixeira was involved in a home-plate collision with Bobby Wilson while sliding home. Teixeira confessed that the collision was not intentional, and was not disciplined by the league for his action. On May 8, Teixeira became the second Yankees player to hit three home runs in one game against the Boston Red Sox, joining Lou Gehrig, who accomplished the feat on June 23, 1927. On June 20, against the New York Mets, Teixeira hit a grand slam off Johan Santana, proving to be the Yankees' only offense of the game in the 4–0 victory. Once again, Teixeira won the 2010 Gold Glove Award for American League first basemen. In 158 games of 2010, Teixeira finished with a .256 average, 33 home runs, and 108 runs batted in. He also led the American League with 113 runs scored. In the 2010 ALCS, Teixeira injured his hamstring, and did not play for the remainder of the playoffs. The Yankees lost the series to the Rangers in six games.
