Kaelen Culpepper, SS, Wichita (MIN No. 5/MLB No. 84)
Culpepper took advantage of the doubleheader yesterday after racking up nine total bases and five hits between the two games. The 2024 first-round Draft pick tied his career high for hits in a single game as he tallied four knocks in the first game, including his 15th home run of the year. Culpepper, who is only a month into his Double-A Wichita career, finishes a monster July with 30 hits, a 1.064 OPS, 8 extra-base hits, and 14 RBIs in 18 games. Gameday (Game 1)

Walker Jenkins, OF, Wichita (MIN No. 1/MLB No. 12)
Jenkins had similar success to his teammate Culpepper as he also had a round-tripper and a double in the two games Wichita played. He had four hits yesterday, to bolster his 2025 resume. The 20-year-old outfield prospect keeps improving with each day. After missing all of May with a left ankle sprain, he still holds a .291 BA, .874 OPS, 5 HRs and 18 RBIs in 43 games this season. Gameday (Game 2)

Matt Koperniak, LF, Memphis (STL No. 22)
Koperniak showed off his power for Triple-A Memphis with two long balls in a 7-4 victory against Norfolk. The two blasts drove in five of the seven Redbird runs. Koperniak, a fifth year pro, now has his third multi-hit game in Memphis’ last five games. In a down year, he finds himself hitting his stride after an impressive month of July. He slashed .299/.337/.584 with 20 RBIs in 20 games this month. Gameday

Brayan Cortesia, SS, DSL Nationals (WAS No. 21)
Cortesia is brand new to professional baseball, but looked very comfortable yesterday for the DSL Nationals where he went 2-for-2 with a whopping four stolen bags en route to a 7-5 victory over the DSL Arizona Black. The 17-year-old Venezuelan was just signed back in January, but has hit his stride seamlessly for the Nationals organization. Cortesia is a speedy shortstop batting .357 with 18 stolen bases in just 27 professional games. It's already the second time this season that the infielder has swiped four bags. Gameday

Brandon Birdsell, RHP, Iowa (CHC No. 8)
Birdsell delivered a gem for Double-A Tennessee, spinning six scoreless frames while allowing just two hits in a win over Indianapolis. The 25-year-old righty walked one and struck out six, marking his first win on the Triple-A affiliate of the 2025 season. This is Birdsell’s first scoreless outing since being activated from the 60-day IL on July 18. Gameday

Chourio impressed in his Single-A debut with Columbia, becoming the youngest pitcher at the level since 2013.
