Fowler went deep for a second straight game for Double-A Trenton on Sunday, his eighth home run this season in 107 games. The 21-year-old outfielder has been on a tear since the All-Star break, hitting .363 with 16 extra-base hits and 25 RBIs over 23 games to lift his overall average to .287.
Weaver, No. 94 on the Top 100, is set to make his debut for Triple-A Memphis. The 22-year-old right-hander was exceptional during his time in the Double-A Texas League, where he posted a 1.40 ERA and a 0.95 WHIP over 12 starts, with 88 strikeouts and just 10 walks in 77 innings. Weaver has been particularly dominant of late, striking out 39 hitters in 33 2/3 innings across his past five starts.
Campos was solid in his D-backs system debut on Aug. 3, scattering four hits over five scoreless innings for Double-A Mobile. Acquired from the Yankees in the Trade Deadline deal that sent Tyler Clippard to the Bronx, Campos, 24, has gone 9-3 in 20 starts across the Class A Advanced, Double- and Triple-A levels, during which he pitched to a 3.20 ERA with 105 strikeouts in 121 innings.
Sims will be looking to notch his fourth straight scoreless start for Double-A Mississippi. He's allowed just six hits over his last 17 2/3 frames while striking out 16, though he has also issued 11 free passes in that span. Sims, 22, has registered a 2.10 ERA with 73 strikeouts over 60 innings (11 starts) while holding opposing hitters to a .170 average.
