Rays acquire former first-round RHP from Pirates

The Rays have acquired right-hander Robert Stephenson from the Pirates, reports Rob Biertempfel of The Athletic. Minor league shortstop Alika Williams is heading the other way.

Stephenson, 30, came up as a starting pitcher for the Reds but has been converted to relief work over the past few years. The initial results of the bullpen move were positive, as he posted a 3.76 ERA over 57 appearances in 2019. Things took a downturn in the shortened 2020 season, however, with his ERA shooting up to 9.26 in 10 appearances that year. Prior to 2021, the Reds flipped him to the Rockies in exchange for Jeff Hoffman.

He then bounced back with a solid season in Denver, putting up a 3.13 ERA in 2021. He struggled again in 2022, running up a 6.04 ERA through August before he was designated for assignment and landed with the Pirates. He was able to finish on a high note with a 3.38 ERA in ten appearances for the Bucs down the stretch.

Here in 2023, he began the season on the injured list due to elbow inflammation but was able to return in the middle of April.  He’s since made 18 appearances but has a 5.14 ERA in those. He’s still getting punchouts at a similar rate but his control seems to have fallen off this year. He struck out 26.8% of opponents from 2019 to 2022 and walked 7.9% but those figures are 27.9% and 13.1% this year.

That’s a small sample size but Stephenson has shown himself to be fairly inconsistent in his career, with notable swings in his effectiveness. Nonetheless, the Rays will take a shot at helping him harness his stuff. Given their track record of helping flawed pitchers get the best of their arsenals, it wouldn’t be a total shock to see Stephenson get back on track in Tampa.

Despite their reputation for producing an endless stream of quality relievers, they have had some bullpen struggles this year. They have five relievers currently on the injured list, which is putting a strain on their depth. The relief group as a whole has a collective 4.32 ERA on the season, a mark that places them 22nd out of the 30 clubs in the league. They have been looking in various places for reinforcements, including calling up several arms from their own system as well as signing Jake Diekman after he was released by the White Sox. Now they will add Stephenson as well to see if he can be part of the solution as they try to hold onto the top spot in the cutthroat AL East. He will just be a short-term piece, however, since he’s slated for free agency this winter.

As for Williams, 24, he was the 38th overall selection in the 2020 draft. He has generally been considered one of Tampa’s top 30 prospects in the past few years, with his speed and defense standing out as his best qualities. The key question has been whether or not his bat would allow him to complement those skills. So far, the results there have been somewhat tepid. He hit .267/.312/.375 in 2021 across three different levels, producing a wRC+ of 86. Last year, he got his lineup to .249/.353/.377 for a wRC+ of 104, spending most of his time in High-A. He’s been in Double-A this year, hitting .237/.314/.417 for a wRC+ of 101.

Williams isn’t a star prospect but he comes with a solid floor given his athletic abilities. Any offensive development would be a nice bonus for the Bucs, not a bad outcome for a struggling reliever that they grabbed off waivers less than a year ago.
