Leo De Vries, SS, Midland (ATH No. 1/MLB No. 3)
De Vries' late-season hot streak continued in the opener of Double-A Midland's Texas League semifinal series. The 18-year-old closed the regular season with three homers in his final three games to polish off a .383/.420/.851 slash line for September. De Vries has been impressive since his promotion, batting .281 with a .910 OPS and 13 extra-base hits 21 games for the RockHounds. Gameday

Konnor Griffin, SS/OF, Altoona (PIT No. 1/MLB No. 1)
Griffin's first postseason game did not differ much from the regular-season contests he participated in during his rookie campaign. The 19-year-old reached base four times, doubled and finished with three hits and an RBI to give Double-A Altoona the early edge in its Eastern League semifinal matchup. Drafted ninth overall in 2024, Griffin finished his campaign by slashing .333/.415/.527 with 21 homers, 117 runs scored, 94 RBIs and 65 stolen bases across three Minor League levels. Gameday

Colt Emerson, SS/3B, Tacoma (SEA No. 1/MLB No. 11)
Hitless in his Triple-A debut until the sixth inning, Emerson took care of a few firsts with one swing. The 20-year-old slugged his first long ball for the Rainiers, clubbing a three-run jack. Emerson's breakout season has brought him from High-A Everett to Double-A Arkansas to the brink of the Majors on the strength of a .281 average, an .831 OPS, 47 extra-base hits and 72 RBIs in 125 games. Gameday

Aidan Miller, SS, Lehigh Valley (PHI No. 2/MLB No. 47)
Miller has carried his red-hot stretch to Triple-A, which culminated in his first homer for Lehigh Valley. The Florida native clubbed a solo homer in the opening inning, giving him hits in six consecutive games. Miller also walked twice and has hit safely in 11 of 12 games this month to continue his scorching close to 2025. The 23-year-old is slashing .352/.488/.617 in 34 games since Aug. 1 after batting .193 in June and July. Gameday

Gage Jump, LHP, Midland (ATH No. 3/MLB No. 56)
Jump's successful rookie campaign added an impressive postseason debut for Double-A Midland. The LSU product who was the 73rd overall pick in the last Draft struck out eight over 5 2/3 scoreless innings during his 96-pitch outing. It was a bounceback performance for Gage, who surrendered 21 runs over his final four regular-season starts for the RockHounds. Even with that rough stretch, the 22-year-old posted a 3.28 ERA, a 1.10 WHIP and 131 strikeouts in 112 2/3 innings across two Minor League levels in his first pro season. Gameday

Brody Hopkins, RHP, Montgomery (TB No. 3)
Given an early cushion to work with, Hopkins made it stand up in the opener of Double-A Montgomery's Southern League semifinal series. The 23-year-old wriggled out of a bases-loaded, no-out jam in the second inning by striking out the side and wasn't threatened after that. Hopkins, who fanned seven over five scoreless frames and has surrendered one run in two career postseason starts, sports a 1.22 ERA in 10 starts since the beginning of July. Gameday

George Klassen, RHP, Salt Lake (LAA No. 3)
Klassen delivered a solid Triple-A debut, striking out eight while allowing two runs over six innings for Salt Lake. The Minnesota product has been especially stingy of late, giving up five earned runs over his past five starts (1.55 ERA). Klassen has racked up 40 strikeouts across 29 innings in that span and 134 in 108 2/3 frames across two Minor League levels this season. Gameday

Esmerlyn Valdez, OF/1B, Altoona (PIT No. 15)
Valdez teamed up with Griffin to form a potent 1-2 punch for Double-A Altoona in the club's semifinal opener. The 21-year-old reached base four times and fell a triple shy of the cycle while equaling a career high with five RBIs. The performance put an end to a 2-for-16 slide for Valdez to cap the best season of his pro career. Valdez ended the regular season with a .286/.376/.520 slash line, a personal-best 26 homers and 86 RBIs across two Minor League levels. Gameday
