Mike Sirota, OF, Dodgers: After ranking 20th in the most recent Prospect Hot Sheet, Sirota continued his strong stretch, homering three times in a doubleheader on Thursday. He reached base six times overall, recording four hits and walking twice. Sirota has reached base at least twice in every game this week and is now hitting .325/.464/.649 for the season. He currently ranks 42nd in the Top 100 and is the No. 3 prospect in the Dodgers’ system. 

Bo Davidson, OF, Giants: Davidson had his best game of the season, scoring four runs and recording three hits in an extra-innings win. Two of those hits came as part of Richmond’s 12-run 11th inning, where he drove in four runs on an RBI single and a three-run home run. 

Davidson had struggled to start the year and was only hitting .200/.258/.418 coming into Thursday’s game, but now finds himself hitting .230/.290/.475. Davidson ranks 73rd in the Top 100 and is the No. 3 prospect in the Giants’ system.

Franklin Arias, SS, Red Sox: Arias’ power surge continued with a game-tying home run in the ninth inning Thursday for Double-A Portland. That was the 20-year-old's eighth home run of the season in only 20 games, equaling his total from 116 games in 2025. Arias is currently the No. 2 prospect in the Red Sox system and ranks 46th in the Top 100, but is poised to rise in our next update as we discussed on this week’s Prospect Podcast.

Kayson Cunningham, SS, D-backs: Cunningham recorded four hits, including two doubles, in Low-A Visalia’s 13-12 loss to San Jose. The 19-year-old shortstop is now leading the California League in hitting at .388 and is second in on-base percentage at .495 in his first full season. Cunningham was drafted in the first round on the back of his advanced hit tool and has shown why this year, even though he is one of the younger position players in the league. He ranks 84th on the current Top 100.

George Lombard Jr., SS, Yankees: Lombard hit the ground running Thursday for Scranton, reaching base three times in his Triple-A debut. He walked in his first at-bat and followed that up later in the game with a single to right field and another walk. The Yankees’ No. 1 prospect is off to a great start this season and is now hitting .313/.411/.563 across two levels. He ranks 43rd in Baseball America’s Top 100 and could push for a major league call-up if he continues to perform with Scranton. 

Lazaro Montes, OF, Mariners: After only homering once in the first 20 games of the season, the Mariners' No. 3 prospect homered for the second time in three games in Arkansas’ 11-3 win on Thursday night. The hulking 21-year-old outfielder also tripled, raising his slugging percentage from .375 to .442. Montes is one of the youngest players in the Texas League, but his lack of power so far was surprising, given that he hit 14 home runs in 64 games in Double-A last season. He currently ranks 52nd in the Top 100.

Aiva Arquette, SS, Marlins: Arquette’s first full professional season was delayed after he underwent core muscle surgery during spring training. The seventh pick in the 2025 Draft was activated off the disabled list on Tuesday and recorded one hit in four at-bats in his debut. He was even better in his second game, doubling twice and driving in two as part of Beloit’s 9-4 win over Lake County. Arquette currently ranks as the No. 3 prospect in the Marlins’ system and 40th in the Top 100.

Baseball America Helium Pick Of The Day

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

Herick Hernandez, LHP, Braves: Hernandez had the best start of his professional career on Thursday, throwing seven shutout innings, allowing only one hit and striking out nine. He retired the first 16 hitters he faced before Mac Horvath broke up his perfect game with a triple. Hernandez recorded 20 whiffs in the outing, which led all of Double-A on Thursday. His 1.83 ERA this season ranks second in the Southern League. He is currently the No. 11 prospect in the Braves’ system.
