Connor Norby, acquired by the Miami Marlins during the 2024 trade deadline, is being highlighted as a key player to watch for a breakout season in 2025. After joining the Marlins from the Baltimore Orioles, where he was traded for pitcher Trevor Rogers, Norby quickly rose to become the No. 3 prospect within the team, showcasing his potential with a franchise record of nine extra-base hits in his first 12 games. Despite a challenging rookie season that saw him hitting .236 overall, analysts remain optimistic about his future, citing impressive metrics such as high barrel rates and excellent sprint speed.

As he transitions to third base with Otto López solidifying his place at second, Norby is expected to improve defensively. His strong Triple-A statistics—averaging .294 with an .867 OPS—underscore his offensive capabilities, indicating that a more productive performance in the majors could be on the horizon. Spring Training begins on February 17, offering an early opportunity for Norby to establish himself as a reliable option for the Marlins.

Otto López and Xavier Edwards have emerged as key players for the Miami Marlins, earning pre-arbitration bonuses for their impressive performances in the 2024 season. The MLB distributed a total of $50 million among 101 players who have yet to reach salary arbitration, with López receiving $340K and Edwards $313K.

López, who transitioned from the Toronto Blue Jays to the Marlins, showcased a breakout season with a .270 batting average and 20 stolen bases. Edwards, who took over as shortstop midseason, hit .328 and stole 31 bases, solidifying his role in the team.
