The Chicago White Sox have agreed to acquire veteran right-handed reliever Ryan Tepera from the crosstown Cubs in exchange for lefty prospect Bailey Horn. Both teams announced the deal on Thursday, a day before the 2021 MLB trade deadline.
Tepera, 33, has pitched to a 2.91 ERA and a career-best 4.71 K/BB ratio in 43 1/3 innings for the Cubs this season. Across parts of seven major-league seasons, Tepera owns an ERA+ of 122 in 279 relief appearances and one start. He's owed the balance of an $800,000 salary for 2021 and is eligible for free agency this coming offseason. On the South Side, Tepera figures to fortify a right-handed setup and middle relief corps that has some impressive arms but has been light on depth and consistency.
On the Cubs' side of things, Horn, 23, is a former fifth-round pick out of Auburn. The 2021 season marks his first as a pro, and he's pitched to a 5.63 ERA in 14 games (10 starts) at the Single-A level between Kannapolis and Winston-Salem. In 38 1/3 innings across both levels, he's struck out 45 against 18 walks.
The trade marks the first deal between the two Chicago rivals since the 2017 swap that sent Jose Quintana to the Cubs for a package centered around Eloy Jimenez. Prior to that blockbuster, the White Sox and Cubs had not made a trade with each other since November of 2006, when Neal Cotts went from the South Side to the North Side.
