Because the game will be played in St. Louis under National League rules, there is no designated-hitter slot on this year's ballot.
Ortiz fully supported Youkilis being on the ballot.
"We talked about it," Ortiz said. "He's the guy that plays out there [on defense]. They always come to me [for input] because I've been here longer. This is like the Army. The guy who has the longer [service] time, that's the guy who has the first choice. But I have no problem with that. He deserves it, man. He's been a hell of a player since he's been there."
Youkilis and Ortiz both made the AL team as starters last year, though Ortiz couldn't participate because he was on the disabled list with a left wrist injury.
For the fourth season in a row, Youkilis is off to a red-hot start at the plate.
"He just gets better and better," Ortiz said. "He's been improving himself more and more and more, and that's what the game is all about. The guy wakes up and he could get a hit. It's crazy. That's good. We need guys like that around here."

Ballots will be handed out at every Red Sox home game starting Saturday until June 21.
Youkilis, always a fan favorite at Fenway, figures to get plenty of support.
"He always puts together consistent at-bats," Red Sox third baseman Mike Lowell said. "This is a streak that's ridiculous. He knows the count, he knows what he's looking for, and when he gets his pitch, he doesn't miss it."
Dustin Pedroia, the AL Most Valuable Player in 2008, will try to join teammate Youkilis on the right side of the AL infield for the second year in a row.
The Red Sox are also represented on the ballot by catcher Jason Varitek, shortstop Jed Lowrie, third baseman Lowell and outfielders Jason Bay, Jacoby Ellsbury and J.D. Drew.
Varitek, Boston's captain since 2005, has been an All-Star three times. Lowell made the NL squad three times for the Marlins and the AL squad once for the Red Sox. Drew was the Most Valuable Player of last year's All-Star Game, belting a homer to help fuel the AL to victory. Bay is in the running for his third All-Star appearance, though this would be his first in the AL.
