Royals Outright Daniel Mengden

Sep. 4: The Royals announced that Mengden has cleared waivers and been outrighted to Omaha. Although he has the ability to reject that outright and elect free agency, it seems he will accept, per Lynn Worthy of the Kansas City Star.

Sep. 2: The Royals announced Friday that they’ve recalled right-hander Wyatt Mills from Triple-A Omaha and designated fellow righty Daniel Mengden for assignment in order to create roster space. Mengden was selected to the big league roster just yesterday and started last night’s game for Kansas City, but it appears that’ll go down as a spot start.

Mengden, 29, tossed just 2 2/3 innings in last night’s start against the White Sox, yielding three runs on five hits and a walk with a pair of strikeouts. It was his second stint with the Royals this year, as he’d previously made four bullpen appearances back in June. Overall, Mengden has pitched seven innings with the Royals and allowed four earned runs on ten hits and a walk with eight punchouts.

A fourth-round pick of the A’s back in 2014, Mengden was a regular on the Oakland pitching staff from 2016-20, working primarily as a starter but never quite securing a long-term spot in the rotation. The mustachioed righty appeared in 60 games with Oakland — 48 of them starts — and totaled 302 2/3 innings with a 4.64 ERA, a 17.3% strikeout rate, a solid 7.8% walk rate and 39% ground-ball rate.

Mengden then spent the 2021 season with the Korea Baseball Organization’s Kia Tigers, for whom he notched a 3.60 ERA over the life of 21 starts. He’s spent the bulk of the current season with the Royals’ Triple-A club in Omaha, pitching to a 4.55 ERA in 91 innings. He’s ineligible to be traded because he’s been on a big league roster this year and the trade deadline has passed, so Mengden will hit outright waivers or release waivers within the next seven days. All 29 other clubs will have the opportunity to claim him.

Mills, 27, came to the Royals by way of the June trade that sent Carlos Santana to Seattle. He’s appeared in 18 games out of the Kansas City bullpen already this year but struggled to a 5.30 ERA with a 17-to-10 K/BB ratio in 18 2/3 innings. He’s been sharp in Triple-A for the second straight season, however, and now carries a career 2.53 ERA, a 36.7% strikeout rate and an 8.1% walk rate at that level.
