Tulowitzki was named captain of the National League's Home Run Derby team on Monday, and he immediately named Stanton as one of his top choices for the squad. In the time since, Tulowitzki spoke to the Marlins slugger, who said he was on board.
The Gillette Home Run Derby will take place at Target Field in Minneapolis on Monday, July 14, a day before the All-Star Game.
"I think Stanton's one guy for sure that's going to participate," Tulowitzki said. "I think all the fans, that's who everybody's talking about, his humongous power. I think everybody's excited to see him. He's one guy I've reached out to, and he's going to do it."
Stanton, known for his tape-measure shots, had 21 home runs entering Saturday. Though this is Stanton's fifth season in the big leagues, he has never participated in the Home Run Derby. He was named an All-Star in 2012 but had to skip the event because he had arthroscopic knee surgery.
Tulowitzki and Stanton would fill two spots on the National League's five-man team in the new format for the event. Tulowitzki said he had not decided on any other participants, and though he had exchanged some phone calls and text messages with candidates, he did not offer up any extra names.
And though there has been some talk about adding teammate Justin Morneau -- who made four All-Star appearances from 2007-10 with the host Twins -- Tulowitzki said he was going to hold off to see if the Rockies' first baseman made the squad.
"I think the way that I'm going to go about it is make sure guys are on the [All-Star] team," Tulowitzki said. "I think it's more convenient so they don't have to come in just for the Home Run Derby. He's definitely deserving to be on the team, and I hope so. I think when the announcement comes, if he makes the team, that's when I'll approach him. I don't want him to start thinking about it or anything like that."
Tulowitzki, the owner of 173 career home runs and 18 this season, will be participating in his first Home Run Derby and was named captain because he was the league's top vote-getter when the most recent balloting update was released by Major League Baseball.
The Rockies star, who will compete opposite American League captain Jose Bautista, seems to be taking his duties as captain seriously.
"Being the captain, first and foremost, you want the NL side to have a good showing," Tulowitzki said. "Hopefully someone from our side wins the Derby. For myself, I think [the goal is to] just enjoy the moment, don't put too much pressure on myself as far as hitting a certain amount of home runs. I think just have fun with it and go from there."
This year will feature a new 10-player format that calls for seven outs per round and bracketed play after the first round. The format ensures an NL vs. AL final.
Tulowitzki says he is excited to experience the event for the first time, even if it makes his All-Star break a little more stressful.
"For me, it's a little more nerve-wracking," Tulowitzki said. "In previous years, you go to the All-Star Game, you always want to sit front row for that Home Run Derby and watch and enjoy. It's kind of a day off for you as well, other than just BP at the field.
"This year going in, BP at the field is going to be a job. I'm going to have to be preparing myself for the Derby, and then the next day's obviously the game. It makes my schedule a little bit busier, not that I won't enjoy the moment. It's something I'll always remember, but it does make it a little bit more stressful."
