As summer officially gets underway, some of baseball's most talented prospects have been bringing the heat. C.J. Kayfus lit things up at Triple-A with a grand slam and four hits, Travis Sykora continued his remarkable pitching at Triple-A and teenager Sebastian Walcott put on a show during the Pipeline Showcase. But a veteran of the game -- Chad Wallach -- put together the most product game of the night, hitting a pair of grand slams in a career-best performance.
Max Clark, OF, West Michigan (DET No. 1/MLB No. 7)
A relatively quiet month from Clark has gotten louder as June winds down. The 20-year-old went deep for the second consecutive game and collected a pair of hits for the third straight contest for High-A West Michigan. Clark has gone 6-for-11 with three extra-base hits in that span and sports an .830 OPS, 40 RBIs and 39 runs in 59 games. Gameday
Sebastian Walcott, SS/3B, Frisco (TEX No. 1/MLB No. 9)
Walcott has put together a solid season as a 19-year-old at the Double-A level, albeit with some inconsistencies. But the teenager stood tall during the Prospect Showcase, collecting a pair of singles and equaling a career high with three stolen bases, giving him 15 on the year. Full story | Gameday
Carson Williams, SS, Durham (TB No. 1/MLB No. 20)
After struggling for much of the first two-plus months of the season, Williams has hit his first extended hot stretch. The Rays' 2021 first-rounder homered for the second straight game, doubled and reached base three times while extending his hitting streak to five games. Williams, who has raised his average 30 points since June 1, has gone 10-for-21 with five extra-base hits and eight RBIs in that stretch. Gameday

Travis Sykora, RHP, Wilmington (WSH No. 1/MLB No. 55)
Sykora's season has reached the point where allowing runs might be considered more noteworthy than when he doesn't. The Texas native lowered his ERA for High-A Wilmington to 1.21 after equaling a career high with six scoreless frames. Sykora struck out eight while surrendering two hits and two walks. The 21-year-old has been virtually unhittable in 10 starts across three Minor League levels, posting a 1.11 ERA and an 0.61 WHIP with 70 strikeouts in 40 2/3 innings. Gameday
Hunter Barco, LHP, Indianapolis (PIT No. 5/MLB No. 86)
Barco has found the going tougher in Triple-A after being unscored upon in his first six starts of 2025 with Double-A Altoona. But the 24-year-old southpaw reverted to his early-season form for Indianapolis, spinning a career-high six scoreless frames, striking out six. A second-round pick out of Florida in 2022, Barco has a 2.11 ERA and 67 K's in 51 1/3 innings across two Minor League levels this season. Gameday
C.J. Kayfus, 1B/OF, Columbus (CLE No. 5/MLB No. 94)
Kayfus continued his strong season by matching a professional high with four hits, highlighted by his second career grand slam. The 23-year-old has been one of Triple-A Columbus' most consistent hitters since Opening Day, carrying a .306/.367/.559 slash line with 32 extra-base hits and 38 RBIs in 63 games after driving in 92 last year. Gameday
Chad Wallach, C, Salt Lake (LAA, Unranked)
Wallach hit a pair of grand slams during a three-hit night that accounted for all of his career-high eight RBIs for Triple-A Salt Lake. The Cal State Fullerton product and veteran of 155 big league games has enjoyed a productive month at the plate, homering four times and driving in 13 runs in seven games. Gameday
