Zac Veen emerges as a prime fantasy baseball waiver wire candidate following his promotion by the Colorado Rockies. Known for his speed and power, Veen had an impressive spring training with a .270 average, two home runs, and nine stolen bases. Having stolen 55 bases over two minor league levels in 2024, he showcases a high SB ceiling, making him a must-add for those needing speed in roto leagues.

At just 23 years old, Veen's potential is significant, having previously ranked as MLB Pipeline's No. 27 prospect. With Coors Field as his backdrop, he could finish the season with double-digit home runs and over 25 stolen bases. His minor league performance, including a .387 batting average at Triple-A, suggests he is ready to make an immediate impact.

Chase Dollander made a strong major league debut as the Colorado Rockies defeated the Oakland Athletics 12-5, showcasing the team's commitment to their youth movement. Dollander's promotion comes amidst a roster shakeup, with Zac Veen also set to join the 26-man roster after impressive performances in Triple-A. The Rockies, despite a rocky start to the season, are optimistic about improvement, especially with Veen's potential to energize a struggling offense that is currently hitting just .667 OPS.

General Manager Bill Schmidt and Manager Bud Black have emphasized performance over service time considerations in their roster decisions. Veen's call-up was precipitated by the struggles of current left fielder Jordan Beck, who has been unable to produce at the plate. Dollander's elevation was necessitated by Austin Gomber's injury, highlighting a need for immediate pitching depth. As the Rockies aim for progress, the arrival of these two highly touted prospects could mark a turning point in the franchise's trajectory.

The 2025 MLB Rookie of the Year race is heating up with prospects like Roman Anthony leading the charge for the Boston Red Sox. Despite a shaky start, his offensive upside keeps him at the top of lists, making him a must-watch for fantasy managers. Zac Veen of the Colorado Rockies is also drawing attention, showing promise with his recent performance and injury recovery, making him a worthy add in many leagues.

Jordan Lawlar has stepped up for the Arizona Diamondbacks, especially after Ketel Marte's injury, while Rhett Lowder's injury puts a damper on his potential contributions for the Reds. Meanwhile, Nick Kurtz's explosive start at Triple-A makes him an intriguing option for power-hungry fantasy teams, despite potential delays in his promotion.

Week 2 of the 2025 MLB season brings exciting developments for dynasty fantasy baseball enthusiasts. Notable prospect call-ups have occurred, including Chase Dollander of the Rockies, whose fastball boasts an impressive 21% swinging-strike rate. Despite allowing four earned runs in his debut, his strikeout potential is evident. Thomas Harrington also made his major league debut, facing challenges but with a previously strong command that suggests he can bounce back quickly. Meanwhile, Zac Veen has shown significant improvement, combining speed and power, making him an excellent addition to fantasy rosters.

In terms of trends, bat speed is stabilizing rapidly, which could impact draft strategies. Players like Jesse Winker and Brendan Rodgers have recorded notable increases in bat speed, promising efficiency at the plate. On the buy/sell side, Tyler Soderstrom is a hot buy due to his early-season power surge, while Anthony Volpe may be a candidate for selling high, as he struggles with contact despite his current hot streak.

As the 2025 MLB season unfolds, the focus shifts to the prospects who are primed to make a significant fantasy impact. Notable promotions last week included Chase Dollander and Zac Veen to the Colorado Rockies, marking them as key players to watch. This week's prospect rankings spotlight players such as Nick Kurtz of the Athletics, who boasts a .452 batting average with four home runs in Triple-A. Meanwhile, Colson Montgomery of the White Sox has struggled, while his teammate Chase Meidroth has shone, hitting .333 and delivering solid power metrics. Dalton Rushing of the Dodgers is emerging as a potential starter following injuries to teammates, while Jordan Lawlar, despite missing an expected call-up, is showcasing his ability in Triple-A. These prospects represent a mix of ready talent and future stars, making them valuable additions for savvy fantasy managers.
