The slugger holds the lead at designated hitter with 1,045,283 votes.
Though he started his season a couple of weeks late due to the right Achilles problem that sidelined him at the end of 2012, Ortiz has quickly made up for lost time.
In 39 games, Ortiz is hitting .333 with 10 homers, 36 RBIs and a 1.023 OPS.
Ortiz's ability to adapt in his late 30s and still produce at such a high level has been impressive. Manager John Farrell started to see the transformation the last couple of years when he was game-planning against Ortiz for the Toronto Blue Jays.
"Across the field, you saw him with more of a willingness to use the wall and to stay inside of pitches that he's used to hit the ball the bigger part of the field," Farrell said. "I think it's allowed him to see the ball better and track the ball longer and maybe, in my own description, say he's not afraid to get jammed. He's not afraid to let the ball get deep, and he's so strong, he can fight base hits off the other way."
Ortiz has been selected to the All-Star team in eight of the last nine seasons.

Last year, Ortiz was Boston's only representative at the All-Star Game.
However, this year, some other players are making a strong push, none more than Dustin Pedroia.
The second baseman has been unstoppable at the plate in recent weeks while also making a highlight-reel play in the field in just about every game.
With 642,419 votes, Pedroia ranks third at his position, behind Robinson Cano (1,235,230) and Ian Kinsler (656,827). Pedroia is trying to become an All-Star for the first time since 2010, and the fourth time overall.
Mike Napoli, who has switched positions from catcher to first base this season, is currently third with 380,448 votes, but is well behind leaders Chris Davis (1,176,016) and Prince Fielder (1,059,300). Napoli has been one of the top run producers in the AL this season, his first with the Red Sox.
Catcher Jarrod Saltalamacchia ranks fifth at his position with 331,444 votes, trailing Joe Mauer, Matt Wieters, Carlos Santana and A.J. Pierzynski.
Jacoby Ellsbury, who has caught fire of late, is ninth in the outfield with 473,877 votes. Teammate Shane Victorino is 14th with 341,733 votes. Torii Hunter is currently in control of the third and final outfield berth with 761,937 votes.
