A week ago, Youkilis led Teixeira by a miniscule 1,315 votes. Now, in the latest ballot update announced Monday, Teixeira has jumped ahead by 35,632 votes -- with a total of 1,561,292 -- as both bid for their second All-Star Game start at first base.
Teixeira, whose once-frenetic homer pace has slowed in recent weeks, still leads the Yankees in home runs and RBIs, and is now flirting with a .300 average after hitting merely .200 in April.
Derek Jeter, meanwhile, continues to lead all AL shortstops in voting, remaining well ahead of Jason Bartlett of the Rays and rookie Elvis Andrus of the Rangers. Jeter is the AL's top vote-getter with more than 2.5 million votes.

Alex Rodriguez, who sat out two games last weekend with fatigue, ranks second in third base voting behind Evan Longoria of the Rays. But because Rodriguez missed over a month of the season following hip surgery and has slumped for much of June, fan balloting is likely his only potential ticket to a 13th career All-Star Game.
Other Yankees with a chance include Robinson Cano, who ranks third among second basemen; Jorge Posada, who is second among catchers; and Johnny Damon, who ranks seventh among all outfielders.
