Diamondbacks Designate Gavin Hollowell For Assignment

By Darragh McDonald | August 20, 2024 at 2:30pm CDT

The Diamondbacks officially announced their signing of infielder Luis Guillorme, which was reported earlier today. In corresponding moves, they optioned infielder Blaze Alexander and designated right-hander Gavin Hollowell for assignment.

Hollowell, 26, has never pitched for the D’backs at the big league level. He had spent his entire career with the Rockies until they put him on waivers in June. The Snakes claimed him at that time but mostly have kept him on optional assignment since then. He was briefly recalled at the start of July but was optioned back down to Triple-A Reno a day later without getting into a game.

The Snakes were likely intrigued by his big strikeout numbers in the minors. Those have sometimes come with plenty of walks, which was certainly the case after switching organizations. In 17 1/3 Triple-A innings since coming to the Diamondbacks, he has a 3.63 earned run average and 30.4% strikeout rate but a huge walk rate of 16.5%. Combined with his time in the Rockies’ system earlier this year, his 2024 season consists of 23 2/3 minor league innings with a 5.70 ERA, 29.5% strikeout rate and 16.1% walk rate.

Those control issues weren’t as bad in previous seasons. He tossed 96 minor league innings over the 2021 to 2023 period with an even 3.00 ERA, 32% strikeout rate and 8% walk rate. He also tossed 40 2/3 major league innings for the Rockies with a 6.20 ERA, 21.5% strikeout rate and 11.8% walk rate.

He’s now been squeezed off Arizona’s roster. With the trade deadline in the rear-view mirror, they will have to put him on waivers in the coming days. Though the control hasn’t been there this year, his strikeout stuff could intrigue some clubs around the league. If he is claimed, he will still have an option year remaining after this campaign, giving him some future roster flexibility. He also has less than a year of major league service time, meaning a claiming team could control him well into the future.
