The Boston Red Sox announced several roster changes on Friday, highlighted by right-hander Johan Oviedo being placed on the 15-day injured list with a right elbow strain. Oviedo, 28, was sidelined following a rough start to the season and a pronounced drop in velocity. The Red Sox also recalled right-handers Tyler Uberstine, who will make his major league debut, and Zack Kelly, while Garrett Whitlock was placed on the paternity list for up to three days.
Oviedo, acquired in the offseason in a trade that sent highly touted outfield prospect Jhostynxon Garcia to Pittsburgh, showed promise during spring training. Over four starts, he pitched 11 1/3 innings, allowing just two runs on eight hits and striking out 14 batters.
Johan Oviedo’s Elbow Strain Raises Concerns After Reduced Velocity Performance
However, his final spring outing was less encouraging, giving up six runs, and his official Red Sox debut was marred by four runs, six hits, including two home runs, and a walk over 3 2/3 innings of long relief against the Astros.
More concerning than the results was Oviedo’s velocity. Historically averaging above 95 mph on his four-seamer, he saw it dip to 93 mph in Houston, with all his pitches showing reduced speed. Manager Alex Cora initially attributed the decline to mechanics rather than injury, but further evaluation, including X-rays and an MRI, revealed a right elbow strain.

While a strain may carry less concern than a ligament-related sprain, flexor tendon strains can still require extended absences. Oviedo, who last pitched on March 30, missed all of 2024 and most of 2025 due to Tommy John surgery in December 2023, adding context to the caution around his health.
Tyler Uberstine’s Unconventional Journey Leads to Red Sox Major League Debut
Meanwhile, Uberstine’s promotion marks a significant milestone. The 26-year-old was added to Boston’s 40-man roster last November and excelled in 120 2/3 innings across Double-A and Triple-A last season, posting a 3.58 ERA and striking out 26.9 percent of hitters while walking only 8 percent.
Uberstine’s path to the majors has been unconventional. He barely pitched in high school, faced setbacks at USC, and had a 5.90 ERA in his final Northwestern season. Drafted in the 19th round in 2021 with a $97,000 bonus, his determination and versatility in multiple pitching roles earned him the promotion.
With Oviedo sidelined and Uberstine stepping into the big leagues, Boston faces early-season pitching challenges. The next few weeks will be important for Oviedo’s recovery and Uberstine’s adjustment to major league competition.
