The Philadelphia Phillies officially won this trade with the Oakland A’s.

Philadelphia Phillies president of baseball operations Dave Dombrowski has a long history of winning trades, and that list just grew a little longer.

The Oakland A’s released pitching prospect Billy Sullivan this week, who they acquired from the Phillies in a trade for outfielder Cristian Pache in March 2023.

Sullivan, 25, never appeared in a major league game for the A’s. He struggled at Triple-A Las Vegas last year with a 5.34 ERA and a 1.76 WHIP in 57 1/3 innings. He was even worse this year, allowing 13 runs and 10 walks in just 5 1/3 innings before being released.

Meanwhile, Pache has been a solid fourth outfielder for Philadelphia, batting .242/.330/.407 in 53 games for the Phillies and recently notching his first career walk-off hit. He could see more playing time soon as well given the struggles of Johan Rojas, who’s batting just .200/.280/.244.

Pache, 25, has emerged as a key bench player for Philadelphia. Meanwhile, Sullivan is still trying to reach the majors, let alone claim a consistent role there.

Given his recent control problems, Sullivan’s MLB future appears in doubt. If he couldn’t get a roster spot on the A’s — one of the worst teams in baseball — it’s hard to imagine him finding a new job elsewhere.
