Pitcher Adonis Medina was signed by the Philadelphia Phillies as an international free agent before the 2014 season. He spent that year with the DSL Phillies, going 2-3, 1.37 in 11 games, before moving to the GCL Phillies in 2015. There, he was 3-2, 2.98 in 10 games.
In 2016, he went 5-3, 2.92 for the Williamsport Crosscutters of the New York-Penn League, making 13 starts and logging 64 2/3 innings. he struck out just 34 batters, but his strikeout numbers shot up in 2017, as did his prospect rating. Pitching for the Lakewood Blue Claws of the South Atlantic League, he went 4-9, 3.01, but with 133 Ks in 119 2/3 innings. In 2018, he was sent to the Clearwater Threshers of the Florida State League and it was his solid strikeout rate that got him a spot on the World team for the 2018 Futures Game. However, he was roughed up when he took the mound, as while he was credited with two strikeouts in a third of an inning, one of those batters reached base on a dropped third strike, and this was immediately followed by a monstrous two-run homer by Peter Alonso; before that, Jo Adell had hit a double and scored on a passed ball and the wild pitch on the strikeout, and the three runs he gave up saddled him with the 10-6 loss.
After spending most of the 2020 season in the Phillies' alternate training site, he was called up to make his debut as the starting pitcher against the Toronto Blue Jays with both teams in the midst of a pennant race on September 20th. Things didn't start well as he allowed a run before retiring a batter, by walking Cavan Biggio, allowing a double to Bo Bichette, and then balking in a run, before he got Teoscar Hernandez to pop up in foul territory. A single by Lourdes Gurriel resulted in another run but struck out Randal Grichuk and got Vladimir Guerrero Jr. to ground out to limit the damage. But he settled down after those early jitters and did not give up another run in 5 innings. But, the Phillies' relievers were unable to keep the game close and he was charged with a 6-3 loss.
