Prospect Wire, powered by Louisville Slugger, is Baseball America’s new free home for in-season daily news, analysis and filterable season stats for every player ranked in a Top 30. Check that out here.

C.J. Kayfus, 1B/OF, Guardians: The Double-A Akron left fielder/first baseman went 2-for-6 with two home runs on Tuesday, raising his Double-A numbers to .317/.435/.644 and he’s now hitting .329/.436/.604 overall. Kayfus has hit 15 home runs, four triples and 17 doubles. He’s been one of the prospect breakouts of the 2024 season and he’s added to what is an impressive collection of Guardians’ first base prospects.

Adrian Del Castillo, C, D-backs: Del Castillo went 3-for-4 with three home runs, four RBIs, four runs scored and a walk in Triple-A Reno’s 14-10 win over Round Rock. Del Castillo now has 20 home runs this year. He’s hitting .332/.410/.636 while also serving as the Aces’ primary catcher. The D-backs’ 2021 supplemental second round pick has not slugged .500 in any MiLB season as a pro, and his 20 home runs is already six more than he’d hit in any previous season.

Leodalis De Vries, SS, Padres: Considering the Padres’ aggressive assignment of their 17-year-old wunderkind, patience is required when evaluating his first foray into full-season ball. De Vries is showing signs he may be settling in. The No. 66 prospect in baseball hit another home run Tuesday, bringing his total to four in his last three games. He’s hitting .440 in July with more walks (five) than strikeouts (four) during his six-game heater. We discussed De Vries’ season and how Padres GM AJ Preller may approach the trade deadline on this week’s Hot Sheet show.

Travis Sykora, RHP, Nationals: Sykora turned in another sterling outing Tuesday, striking out seven batters over five hitless innings for Low-A Fredericksburg. Sykora now has 16 strikeouts to just three walks and one hit allowed in 10 innings this month, and he hasn’t allowed more than two earned runs in an outing all year. The 20-year-old righty was Washington’s third-round selection last year and now has 63 strikeouts in 45.1 innings on the strength of his mid-90s heater, slider and changeup combination.

Chase Dollander, RHP, Rockies: Colorado’s No. 1 prospect continues to cook for High-A Spokane. Dollander punched out nine batters over three innings against Everett while surrendering just one run. His 111 strikeouts far and away lead the Northwest League and rank fourth among all qualified minor league pitchers. With the draft approaching this weekend, it’s interesting to look back at the previous 18 months for the Rockies righty. He was once considered the top arm in his college class and a potential 1-1 candidate before an inconsistent draft year. He has reverted to his dominant self since Colorado drafted him No. 9 overall that year, and is now one of the top pitching prospects in the sport and No. 24 overall in our Top 100. He has little left to prove in High-A.

Robby Snelling, LHP, Padres: It’s been a trying season for Baseball America’s 2023 Minor League Pitcher of the Year. The 20-year-old lefty owns a 6.14 ERA in 70.1 innings for Double-A San Antonio so far and is no longer a Top 100 Prospect. Concerningly, his velocity backed up a tick or two in the first half of the season. But he had it working agains Tuesday night. Snelling registered 19 swings and misses, the most of any Double-A pitcher, while striking out seven Amarillo hitters over 4.1 innings. He allowed three runs on six hits, including a pair of homers, but it’s his second consecutive start with seven strikeouts after a pair of clunkers at the end of June.

Baseball America Helium Pick Of The Day

Elvin Garcia, SS, Orioles: A switch-hitter, Garcia is polished as a hitter from both sides of the plate for a 17-year-old. The DSL has more than its share of pitchers who struggle to find the plate, and Garcia doesn’t make a pitcher’s job any easier. He was walking as much as he struck out as of early July. He should grow into home run power, but he already shows gap power. Garcia has the athleticism, burst, actions and a plus arm to stick at shortstop, and he has a heady approach to the game defensively. Garcia joined the Orioles’ Top 30 in yesterday’s midseason update. We have new additions + risers for every organization below, exclusively for Baseball America subscribers.
