Yates (ankle) was activated off the 10-day disabled list Thursday, Bob Scanlan of FOX Sports San Diego reports.
The Padres optioned the struggling Luis Perdomo down to Triple-A El Paso to clear a spot for Yates as he returns from an ankle injury. Yates cleared his final hurdle in his rehab Wednesday by throwing a live batting practice session and now stands to reclaim his role as the Padres' setup man. He's been a reliable source of strikeouts in recent years, including having a 14.0 K/9 mark in 2017 and a 12.3 K/9 through five appearances in 2018.
