The Blue Jays have claimed Luis Frías off of waivers from the Diamondbacks, according to his transaction log on MLB.com. Arizona designated the right-hander for assignment on Thursday to make room for catcher Andrew Knizner on the 40-man roster. As Ben Nicholson-Smith of Sportsnet first noted, Frías will report to Triple-A Buffalo. Toronto had two open spots on the 40-man roster, so no corresponding move will be necessary.
Frías has spent his entire career in the Diamondbacks organization; he signed with Arizona as a 17-year-old international free agent in 2015. The righty made his MLB debut in 2021, and since then, he has pitched 57 2/3 big league innings with a 6.55 ERA and 5.42 SIERA. He throws hard, averaging close to 96 mph on his four-seam fastball, but he has struggled to induce enough strikeouts at the MLB level. What’s more, he has walked 43 of the 276 batters he has faced; his 15.6% career walk rate is barely lower than his 18.1% career strikeout rate. Unfortunately, his numbers at Triple-A Reno aren’t much better. He has a 4.88 ERA and 6.32 FIP this season in 24 innings pitched. Throughout his career, he has a 4.26 ERA over 124 2/3 innings with the Reno Aces.
All that said, Frías is still just 26 years old, and he was once a relatively well-regarded prospect. Before he graduated from prospect status during the 2022 season, FanGraphs ranked him as the No. 12 prospect in the D-backs system, while Baseball America and Keith Law of The Athletic had him at No. 17. Baseball America ranked him as highly as No. 8 ahead of the 2020 campaign, writing “He could be a force in the rotation if it all clicks. Otherwise, his path might lead him to a high-leverage relief role.” While his days as a starting pitcher are likely all in the past, the Blue Jays must be hoping Frías still has a future as a big league reliever. He’ll provide some extra depth for their bullpen this year, which ranks last in the AL in ERA and second-last in SIERA. As for next year, he’ll be out of options, so Toronto will either need to add him to the Opening Day roster or designate him for assignment.
