The Arizona Diamondbacks activated right-hander Merrill Kelly from the injured list Friday, three days after he was placed there for unspecified reasons.
If it was related to the league's COVID-19 protocols, his activation presumably indicates that he has been cleared or that he felt side effects from a vaccine.
Kelly, 32, is 2-2 with a 5.79 ERA in six starts this season. He has struck out 24 batters, walked nine and allowed five home runs in 32 2/3 innings.
Kelly is 18-18 with a 4.37 ERA in 43 starts since making his major league debut with the Diamondbacks in 2019.
In a related move, Arizona optioned infielder Wyatt Mathisen to Triple-A Reno following Thursday night's 3-1 loss to the Miami Marlins. Mathisen will not report to Reno, however, and will remain with the Diamondbacks as part of the taxi squad.
