The Phillies traded Buchanan to Cincinnati on Tuesday for cash considerations, Matt Gelb of The Athletic reports.
Buchanan returned from several years playing overseas to join the Phillies organization this season and primarily pitched for Triple-A Lehigh Valley. In 22 outings (16 starts) at Triple-A, the 35-year-old logged a 4.91 ERA with a 78:33 K:BB across 102.2 innings. He'll likely report to the Reds' Triple-A affiliate in Louisville.
