Allen, 27, was designated for assignment by the Padres on Dec. 31, and was part of the mega-deal that sent Mike Clevinger from Cleveland to San Diego last August.
The former Indians prospect was drafted in the sixth round of the 2014 draft by Cleveland, and has made 221 appearances in the Majors since his debut on Sept. 1, 2017.
Over 618 plate appearances, Allen owns a career slash line of .239/.298/.343 with 22 doubles, eight home runs, 57 RBI and 32 stolen bases. Allen has MLB experience at all three outfield positions and could compete for a depth role with the Yankees heading into the 2021 season.
Reeves, 27, was a 10th-round pick by the Yankees back in 2015 and reached as high as Triple-A during his time in the organization. The lefty reliever went 7-2 with a 1.87 ERA for Trenton and Tampa back in 2019, and owns a career record of 20-7 with a lifetime 2.30 ERA across his Minor League career.
Reeves played four collegiate seasons at The Citadel in Charleston, South Carolina, going 20-11 with a 3.88 ERA over 239 innings. He'll join a Padres farm system that ranks among the best in baseball, per MLB.com.
