ST. LOUIS -- One way or another, Marlins first baseman Justin Bour will have a presence in the All-Star festivities. The 29-year-old announced on Monday that he will participate in the T-Mobile Home Run Derby next Monday at Marlins Park.
It could be an even more hectic week for Bour if he's also selected to the MLB All-Star Game presented by Mastercard on July 11, at 7:30 p.m. ET on FOX. He's one of five candidates vying for the Esurance MLB All-Star Final Vote.

The campaign is heating up, as his teammates are lobbying for him, and several players wore #VoteBour T-shirts on Monday before the Marlins' 14-6 loss against the Cardinals at Busch Stadium. Bour did his part, going 2-for-4 with an RBI double and a walk.

The lone player currently in the big leagues to attend George Mason University, Bour is extremely popular with his teammates and known for his sense of humor.

"His numbers deserve it more than his sense of humor," Marlins right fielder Giancarlo Stanton said. "But that's also a plus that people don't always get to see."
If elected to his first All-Star Game, Bour would give the Marlins three representatives in this year's Midsummer Classic. Marcell Ozuna was voted in by the fans as a starting outfielder, while Stanton was selected as a reserve.
• Interactive All-Star roster
Voting for the final spot on the roster ends at 4 p.m. ET on Thursday. Fans can show their support for Bour by tweeting with #VoteBour, and from 10 a.m. to 4 p.m. ET on Thursday, any tweet that includes #VoteBour will count toward his vote total.

The other finalists for a spot on the NL roster are Cubs third baseman Kristopher Bryant, Nationals third baseman Anthony Rendon, Rockies first baseman Mark Reynolds and Dodgers third baseman Justin Turner.

Bour and Stanton are commitments from the Marlins to participate in the Home Run Derby, set for July 10 at 8 p.m. ET on ESPN.
"I didn't watch much baseball growing up," said Bour, who has hit 18 homers. "I liked to play it, but the Home Run Derby is something you've got to sit down and watch and enjoy. To be a part of that and have my family come out and be there with me, it's going to be a very special moment."

Stanton is the reigning Derby champion, winning in record-setting fashion last year with 61 belted at Petco Park in San Diego.
Also committed to this year's event are the Twins' Miguel Sano and the Yankees' Aaron Judge and Gary Sanchez. Dodgers rookie Cody Bellinger is also likely to participate, pending the availability of his father, Clay, a former Yankees outfielder now working as a firefighter in Gilbert, Ariz., to pitch to him.

Marlins outfield coach Lorenzo Bundy will pitch to Bour in the Derby, and Stanton is bringing back Pat Shine, formerly on Miami's staff but who now is a coach in the Mariners system. Shine threw to Stanton last year.
Manager Don Mattingly said Bour is ideal for the Derby because he has a swing that shouldn't be impacted.
"He'd be a good guy for it," Mattingly said. "I don't think it will really mess with his swing that much. He's a guy who can hit them a long way. He'll be fun in Miami. Hopefully he will put on a good show."
Eleven of Bour's home runs have come at Marlins Park, and Stanton has 13 at home (21 total). Per Statcast™, the average distance of Bour's shots is 396 feet, compared to Stanton's 405 feet. The average exit velocities of Stanton's homers at home is 107.9 mph, and Bour's is 104.5 mph.
