Kuhnel, 29, has been featured in the pages of MLB Trade Rumors plenty of times this year but hasn’t been able to factor into many MLB games. He started 2024 on the Astros’ roster but was designated for assignment, outrighted and elected free agency before re-signing with Houston on a minor league deal by the end of January. He was selected back onto their roster in April but then designated for assignment again later that month.

He then went to the Blue Jays in a cash deal but that club kept him on optional assignment for a few weeks before he was designated for assignment and elected free agency once again. He landed with the Brewers on a minor league deal and was twice selected to that club’s roster but both stints resulted in him being designated for assignment without him pitching in a game.

Around all of those transactions, he only has one appearance in the big leagues this year, when he allowed four earned runs in two innings for the Astros. But in his 27 1/3 minor league innings, he has a 2.30 earned run average. His 15% strikeout rate is subpar but he’s racked up huge numbers of ground balls.

That’s generally been the recipe for Kuhnel in his career. He has 85 2/3 big league innings overall, most of that with the Reds. His 6.30 ERA in that time obviously isn’t great, nor is his 19% strikeout rate, but he has kept 52.2% of balls in play on the ground and has clearly attracted the attention of several clubs around the league.

The Rays have a bunch of open roster spots right now. In the past month, they have traded Aaron Civale and Phil Maton. They also designated Chris Devenski for assignment and put Yandy Díaz on the restricted list due to an undisclosed personal matter. Tyler Zuber was selected to take one of those spots but they still had three available and have now used one of them on Kuhnel.

Kuhnel averages in the mid-90s with both of his fastballs and also throws a slider and a changeup. Given that velocity and pitch mix, perhaps clubs around the league believe there’s room to coax some more strikeouts out of him, in addition to his ground ball tendencies. He is also in his final option year and can therefore be sent to the minors for the rest of this season. His service time count is between one and two years, so he could be a long-term piece if things break right.
