With the 2025 fantasy baseball season heating up, identifying key prospects is crucial for managers aiming to enhance their rosters. In Week 12, focus shifts to three standouts rising through the ranks. Colson Montgomery of the Chicago White Sox, a former top prospect, is showing signs of improvement after a rocky start to the season, boasting a recent .271 batting average with four home runs in his last 19 games. His elevation to the majors could be on the horizon, but redraft leagues should tread carefully. On the pitching side, Jonah Tong of the New York Mets is making waves as a potential MLB debutant. His impressive strikeout rate and low ERA at Double-A make him a hot commodity for fantasy managers looking for pitching depth. Meanwhile, Chase Burns of the Cincinnati Reds, selected second overall last season, is already dominating in the minors, with a remarkable 1.29 ERA at Double-A, positioning him as a must-stash player. Each of these prospects could play a pivotal role in your fantasy success this season.
