Players who were once part of the New York Mets and Yankees organizations are experiencing significant success in new environments this season. Several former prospects have made successful transitions, earning opportunities and contributing to their current teams.
Among those finding new life is T.J. Rumfield. The Rockies acquired the left-handed hitting outfielder from the Yankees on January 28. Rumfield, who would have turned 26 in May, had spent two seasons at Triple-A and was not on the Yankees' 40-man roster. He was passed over in the Rule 5 draft a month prior to the trade. As a left-handed-hitting first baseman, he was also blocked on the Yankees' roster by Ben Rice.
Rumfield had a strong spring training, earning a spot on the Rockies' roster. His offensive production has steadily increased each month, starting with an OPS of .743, moving to .883, and reaching .989 in June. That performance earned him NL Rookie of the Month honors for June. The Rockies, who had the fewest left-handed plate appearances in 2025, were specifically looking to add power and depth from that side of the plate.
Earlier in the month, the Rockies had also acquired outfielder Jake McCarthy from the Diamondbacks for pitcher Josh Grosz, who was part of the return from the Yankees last July for Ryan McMahon. Additionally, the team signed switch-hitter Willi Castro and acquired Edouard Julien from the Twins. Julien had major league experience dating back to 2023 and finished seventh in AL Rookie of the Year voting that year. The Rockies' strategy focused on acquiring players in their 20s who may have faced obstacles with their previous organizations but possessed desirable profiles.
In another notable move, the Yankees were focused on adding power and depth to their bullpen. They had previously found success by developing talented arms like Angel Chivilli, refining their mechanics and pitch sequencing. Chivilli has made two appearances for the Yankees this year.
