Cole Mathis, 3B, Cubs: Desperate for pitching, the Cubs made a move late Wednesday night to acquire veteran starter David Peterson from the Mets in exchange for Mathis, their No. 9 prospect.

Mathis, the Cubs' 2024 second-round pick out of the College of Charleston, has performed well when healthy, but has also dealt with elbow injuries in each of the previous two seasons, including Tommy John surgery in 2024. The 22-year-old has hit .272/.396/.585 over 39 games between the two Class A levels this season, though he hasn't played since June 10 and is currently on the injured list. Mathis' plus raw power and solid bat-to-ball skills provide a path to developing into a second-division regular if he can find a way to remain healthy.

Jefferson Rojas, SS, Cubs: Rojas has been scorching hot in June and he took it up a notch Wednesday, smashing two homers in a 3-for-5 effort for Double-A Knoxville. The Cubs' No. 1 prospect is hitting .386/.424/.699 through 23 games. Rojas has a strong combination of bat-to-ball skills, approach and power. He should debut at some point in 2027 and could fill multiple positions in the Cubs' infield one day.

Mike Sirota, OF, Dodgers: The Reds have to be kicking themselves every time they see more Sirota highlights. On Wednesday, the Dodgers outfielder extended his on-base streak to 60 games. Sirota went 1-for-4 for Double-A Tulsa, extending a streak that began early this season with High-A Great Lakes. The 23-year-old outfielder is hitting .323/.472/.562 with 11 homers over 65 games this season and currently ranks No. 17 on our Top 100 Prospects list.

Demetrio Crisantes, 2B, D-backs: Crisantes has struggled to stay healthy, but few question his ability. Since returning from a hamstring strain that cost him the first two months of the season, Crisantes has been excellent for Double-A Amarillo, and that continued Wednesday when he went 3-for-4 with a home run, a double and four RBIs. Crisantes is now hitting .348/.450/.636 across 17 games as he looks to recoup development time after a shoulder injury limited him to 34 games in 2025.

David Hagaman, RHP, D-backs: Hagaman and Blue Jays LHP Johnny King engaged in an old-fashioned pitching duel Wednesday in the Northwest League. King struck out six over five innings of one-run ball, but Hagaman one-upped him. The former West Virginia star went six scoreless innings allowing two hits and three walks while striking out eight. Hagaman's in the midst of his best month of the year, as he has pitched to a 3.15 ERA in June.

Editor’s Picks

Baseball America Helium Pick Of The Day

Each day, we’ll pick a prospect that has our attention.

Wilberson De Peña, OF, Yankees: Acquired in the deal that sent infielder Oswald Peraza to the Angels, De Peña has been a hitting machine in the FCL. The cherry on top of his season came on June 22, when the outfielder went 6-for-7 with three doubles in his team's rout of the Tigers. De Peña's name is all over the FCL leaderboards, and evaluators in the league see a player with the potential for average hittability and power and enough defensive chops to move around the outfield.

Quick Hits

Prospect news and notes from around baseball…

• A’s LHP Gage Jump continues to flourish in the big leagues. He struck out nine Giants batters to just one walk over five scoreless innings Wednesday. Jump now has a 2.04 ERA over 35.1 innings with 35 punchouts to 10 walks.

• The following prospects all clubbed two homers yesterday:

  • Marco Dinges, Brewers (High-A)

• Cubs outfielder Josiah Hartshorn continued his torrid pace in High-A, going 3-for-5 with a homer.

• Red Sox lefty Dylan Brown struck out 11 batters over seven scoreless innings for High-A Greenville. Back in April, Baseball America’s Ian Cundall identified Brown as a potential riser this year.

• Yankees RHP Thatcher Hurd is back on the mound, and while his surface-level stats are marred by an ugly 10-run outing in his first game back in Low-A, he has been quite effective since then. Hurd struck out 10 batters over 4.2 scoreless innings, and has allowed just two earned runs over his last 16.2 innings to go along with 27 strikeouts.
