"She said, 'Hit a home run for me,'" said a grinning Wells after his team's 6-2 victory. "Like that's an easy thing to do. I was thinking, 'That's kind of a big request. How about a single or a couple knocks?'"
But Wells indeed delivered the long ball, driving a sixth-inning pitch by Andy Pettitte high off the right-field foul pole for a two-run shot that provided his team a 4-1 lead. It was his first home run of the year.
And for good measure, Wells drove in another run in the ninth with an infield single, with the day's final run scoring as well on a throwing error by Yankees reliever Clay Rapada.
Wells, like most of the Mariners, wore pink wristbands throughout the game as part of Major League Baseball's breast-cancer awareness program.
Three Mariners hitters -- Justin Smoak, Michael Saunders and Jesus Montero -- used pink bats. Montero and reliever Charlie Furbush, who got a critical strikeout of Mark Teixeira with the bases loaded in the eighth, sported pink shoes.
Smoak's bat came through on a 2-for-4 day that included a two-run home run off Pettitte.
"Maybe I'll use that bat again tomorrow," Smoak said with a laugh.
But none of the Mariners were able to deliver quite as much of a personal Mother's Day present as Wells, who gave a quick wave to his mom in the stands after crossing home plate.
"I got a bag for her last year," said Wells. "This year, I got her a home run at Yankee Stadium."
