The Royals announced today that they have reinstated infielder/outfielder Adam Frazier from the injured list and selected the contract of left-hander Walter Pennington. In corresponding moves, they optioned infielder CJ Alexander and right-hander Carlos Hernández. To open a 40-man spot for Pennington, right-hander Dan Altavilla was transferred to the 60-day injured list.

Pennington, 26, signed with the Royals as an undrafted free agent in 2020. That year’s draft was reduced to just five rounds due to the pandemic. Since then, he has been climbing the minor league ladder, getting lots of strikeouts and ground balls but also struggling with command at times.

Last year, he tossed 70 2/3 innings between Double-A and Triple-A, allowing 3.18 earned runs per nine frames. He struck out 25.5% of batters faced and got grounders on more than half of the balls allowed in play, but he also gave out walks at an 11.9% clip. Here in 2024, he’s tossed 53 2/3 innings over 32 Triple-A appearances. He has a huge 35.3% strikeout rate and 52.6% ground ball rate, also reducing his walk rate to 8.8%.

That strong performance will get him called up to the big leagues for the first time. He’ll provide the Royals with a left-handed reliever, one capable of pitching multiple innings per outing. 14 of his 32 appearances this year have been for two innings or longer, with Pennington getting as high as four frames.

As for Altavilla, he landed on the 15-day IL on June 2o due to a right oblique strain. He’ll now be ineligible to return until 60 days from that initial IL placement, which would be the middle of August.
