A little over a week since the United States celebrated its 250th anniversary, more bombs will be bursting in the air when two Philadelphia Phillies participate in Monday's Home Run Derby. 

Designated hitter Kyle Schwarber and first baseman Bryce Harper will square off in the Derby for the first time since 2018, which should provide a show to the hometown fans. 

Phillies Kyle Schwarber and Bryce Harper rank 1 & 2 in the Home Run Derby rankings

With eight participants and 186 combined home runs, Major League Baseball's home run leader, Schwarber (32), and the former Home Run Derby Champion, Harper (2018, 20 home runs), rank No. 1 and No. 2 in MLB's rankings of the participants. Schwarber is making his third appearance, second as a Phillie, while Harper is making his first appearance in a Derby since 2018 when he was a Washington National. 

No hitter has won the Derby in his home ballpark since 2018, when Harper and Schwarber squared off, in which Harper bested his now-teammate -- Schwarber was with the Chicago Cubs in 2018. However, this season could be different, as Schwarber has loved hitting in the confines of Citizens Bank Park. 

Kyle Schwarber has bested Bryce Harper in hitting home runs at CBP

Schwarber has preferred the home cooking of Citizens Bank Park, hitting 19 of his 32 home runs in his home ballpark, while mashing 13 on the road. Harper, on the other hand, has a perfect balance in his split, hitting 10 at CBP and 10 while on the road. 

Schwarber also has his teammate beat in slugging, with Schwarber having a gaudy .663 slugging percentage (163 at-bats) to Harper's .547 (161 at-bats), which is impressive in itself. The two do have one thing in common, though: they're both coming into the Derby blind. 

Playing the Detroit Tigers on the road, Harper said to Todd Zolecki and Steve Kornacki of MLB.com on Friday, "The tough part will be not being able to practice with him before the Derby. So, we’ll go into it a bit blind.”

But with the two Phillies likely on opposite sides of the bracket, fans may struggle with whom to root for. That's not a worry to Schwarber, who believes Citizens Bank Park will be a "cheer factory."

“I believe each of us," Schwarber said to Zolecki and Kornacki. "They’d definitely root for both of us. I think it’d just be a straight cheer factory. So, it wouldn’t be anyone against anyone. It’d be pretty cool.”

Going back to the old format of having 18 swings instead of a clock, it will be telling who the edge between the two All-Stars will have, as the change in rules made Harper hesitant to participate in the first place. 

“That was one of the things that bothered me about it,” Harper said of considering not participating. “The clock, I really liked it. I know a lot of guys didn’t like it because they got tired. I didn’t see it that way. The clock brings that theater part to it. I think the 18 swings are going to take a lot longer. So, the fans will be in for a long night.”
