Schwarber will face eighth-seeded Albert Pujols of the St. Louis Cardinals in the first round.
New York Mets first baseman Pete Alonso, trying to become the first player to win three times in a row, is the No. 2 seed and will take on Atlanta outfielder Ronald Acuna Jr., the seventh seed.

Third-seeded Corey Seager of the Texas Rangers, added to the American League roster as an injury replacement for Tuesday's all-star game, will square off against 21-year-old Seattle rookie Julio Rodriguez, the No. 6 seed.
Seager spent his first seven major league seasons with the Dodgers before signing with the Rangers last off-season.
No. 4 seed Juan Soto from the Washington Nationals opposes fifth-seeded Jose Ramirez of the Cleveland Guardians.
The seeds and matchups were based on the home run totals of each player through July 13.
Alonso hit 74 total home runs in last year's Derby at Coors Field in Denver and beat Baltimore's Trey Mancini 23-22 in the final round.
Alonso joined Ken Griffey Jr. (1998-99) and Yoenis Cespedes (2013-14) as the only players to win consecutive titles. Griffey also won in 1994 and is the lone three-time champion.

Pujols will participate in his fifth Derby after coming up short in 2003, 2007, 2009 and 2015. He and Detroit's Miguel Cabrera were added to the all-star rosters as special selections by commissioner Rob Manfred.
Pujols will make his 11th all-star appearance and compete in the Derby at one of his former homes. He played 85 games with the Dodgers last season after being cut by the Los Angeles Angels, then signed with St. Louis before this season, which he has said will be his last.
The 42-year-old Pujols has six homers this season and 685 in his career, fifth on the career list.
Rodriguez will be the 14th rookie to participate in the Derby, and only two of those have won outright: Alonso in 2019 and Aaron Judge in 2017.
Judge leads the majors in homers with 31 and is set to start the all-star game as the top vote-getter in the AL, but the New York Yankees star is not participating in the Derby.
