Have Mercer: Audacy KKWF/Seattle morning co-host Gabe Mercer is leaving the market to return to sister KMLE/Phoenix, where she will be paired in mornings with Niko Petrou effective April 27. She succeeds Cheyenne Davis, who departed earlier this week (CAT 4/21). Mercer and KKWF morning co-hosts Matt McAllister and "Captain Ron" Koons had also been tracking afternoons at KMLE until McAllister's departure from Audacy earlier this month (CAT 4/3). No word on plans for those dayparts at either station.
