Every year, a handful of players ranked outside the top 10 in their respective farm systems take meaningful steps forward to improve their stock and vault up prospect rankings. Part of the fun is trying to identify those breakouts before it happens. So today, we\u2019re identifying Nationals prospects who have the potential to make a jump in 2026.<\/p>\n
To qualify, a player must rank outside the organization\u2019s preseason Top 10 prospects.\u00a0All scouting reports are from Baseball America\u2019s 2026 Prospect handbook, which you can purchase here<\/a>.<\/p>\n You can find Top 30 prospect rankings\u00a0for all teams here<\/a>\u00a0and all breakout candidates here<\/a>.<\/p>\n Breakout Prospects<\/p>\n Sam Petersen<\/a>, OF<\/p>\n BA Grade\/Risk: 50\/High Track Record: If not for shin splints he contended with as an Iowa junior, Petersen had a chance to be drafted a bit higher than the eighth round in 2024. That\u2019s where he landed with the Nationals, who signed him for a slot value bonus of $230,900. Petersen saw action in seven games for Low-A Fredericksburg after signing but got a late start to his 2025 season after dealing with a hamstring injury. He reached High-A Wilmington on June 5 and then played in the Arizona Fall League after the season to add at-bats.<\/p>\n Scouting Report: Petersen has a strong, 6-foot frame and a hard-nosed playing style. The Nationals have helped coax greater exit velocity out of his righthanded bat, while giving him a chance to prove himself in center field after he played mostly left in college. Petersen hits the ball with authority to all fields with a line-drive approach. He takes aggressive swings and is beginning to take shots to his pull side, with the potential for above-average power. His max exit velocity increased to 110 mph with wood after reaching 109 in 2024 with metal. Petersen does well staying within his zone and keeps strikeouts in check, but his zone-whiff rate of nearly 27% could curtail his production against more advanced pitchers. He is an above-average runner out of the box who is faster underway. His baserunning savvy is apparent in his 18-for-18 showing on stolen bases for Wilmington. Petersen is an average center fielder with a below-average arm that might limit him to left field.<\/p>\n The Future: Petersen was one of the top performers in the South Atlantic League while healthy, which is notable given that Wilmington suppresses home runs like few minor league parks. He showed the potential to be at least a fourth outfielder and potentially a regular if his power and speed continue to play. Petersen is ready for Double-A.<\/p>\n Scouting Grades: Hit: 55 | Power: 55 | Run: 55 | Field: 50 | Arm: 40<\/p>\n
