The first wave of results was released on Tuesday, and Miami's third baseman is fifth. Colorado's Justin Morneau leads over Chicago's Anthony Rizzo. Atlanta's Justin Upton is third, followed by Washington's Anthony Rendon, and then McGehee.
But the Marlins have mobilized in an effort to get McGehee the necessary votes by Thursday's deadline. Efforts include radio, newspaper and television ads in South Florida. The Marlins are also getting the word out in Japan for fans to vote for McGehee, who played last year for the Rakuten Golden Eagles.
"It's a full commitment," said Sean Flynn, the Marlins' senior vice president of marketing and event booking. "We're all over it."
In Japan, McGehee was a teammate of current Yankees right-hander Masahiro Tanaka, who used Twitter to encourage his followers to vote for McGehee.
McGehee enters Tuesday batting .322, and he paces the NL in hits with 110. McGehee leads all NL third basemen in RBIs with 53, and he is first in the Majors in batting average with runners in scoring position (.398).
McGehee is riding a career-best 14-game hitting streak, and he's hit safely in 21 straight road games.
"Our goal is getting Casey into the All-Star Game," Flynn said. "There is no doubt he should be in."
Organizationally, the Marlins are having a watch party for Tuesday's game at Arizona, and there will be a voting center to cast votes.
"This is one of the most aggressive Final Vote campaigns," Flynn said.
The Marlins have reached out to their friends at the University of Miami and Florida International University to get the word out to vote for McGehee.
McGehee is scheduled to do radio interviews, and so is slugger Giancarlo Stanton, who is currently the lone Marlin selected to the All-Star Game.
The Marlins have partnered with the Astros, who have a Final Vote candidate in the American League in pitcher Dallas Keuchel. Houston is pushing McGehee in its market, and Miami is throwing its support behind Keuchel.
On Monday, the Marlins reached out to their contacts with the D-backs, and they had a local Arizona vendor print up #VoteHitsMcGehee T-shirts.
Flynn said the Marlins contacted the vendor at 11 a.m. ET on Monday, and by batting practice, each Miami player and member of the coaching staff sported a McGehee T-shirt.
Perhaps the biggest push McGehee could receive will come from Japan. A year ago, McGehee was part of the Golden Eagles' championship team.
Already, the "Vote McGehee" campaign has reached McGehee's former team and his ex-teammates. The Japanese media has picked up on the campaign.
"Tanaka has jumped on board," Flynn said. "It's huge if we can activate Japan to get on this train."
