PHILADELPHIA – Seven alumni from the University of Pennsylvania baseball team continued to compete in the professional ranks across several levels this summer.
Of the seven, four played college baseball at Penn within the last four seasons. Matt O'Neill W'19 reached as high as Triple-A during the course of the 2026 season, while Jake Cousins C'17 secured a move to the Los Angeles Dodgers following stints with the Milwaukee Brewers and New York Yankees.
C Jackson Appel W'23 – Chicago White Sox (High-A)
Following a solid second season in 2025 with the High-A Winston-Salem Dash, Appel has spent most of the 2026 campaign on the 60-day injured list. In just six games and 15 at-bats, the switch-hitting catcher batted .267, racking up three singles and a home run.
Once he returns from injury, he will look to build upon his sophomore professional season which featured 64 hits, 25 RBIs, 13 doubles, a home run, and 11 stolen bases with a .248 batting average. His 78 starts behind the dish and .985 fielding percentage eventually earned him a move to Double-A competing with the Birmingham Barons. Appel will hope to hit the ground running as he nears a return to the diamond.

RHP Jake Cousins C'17 – Los Angeles Dodgers (MLB)
During the 2024 season, Cousins became the first Penn Quaker to appear in a World Series game in over 100 years. He was later ruled out for the 2025 season due to Tommy John surgery and sent to the High-A Hudson Valley Renegades for his rehab assignment in June 2025. In early November 2025, the Yankees activated him from the 60-day injured list before he elected free agency weeks later. Cousins signed with the Los Angeles Dodgers in March and has been rehabbing on the 60-day injured list since April 1.
Cousins made a career-high 37 appearances out of the bullpen for the Yankees in 2024 and posted a 2.37 ERA over 38 innings. He also saw action in six postseason games, logging five innings. In 88 career relief appearances over four Major League seasons, Cousins boasts a 5-2 record and 2.78 ERA.
