The Diamondbacks announced that they’ve selected left-hander Matt Grace from their alternate training site. In a corresponding move, they placed southpaw Andrew Chafin on the 10-day injured list with a left finger sprain.
Grace saw action with the Nationals in each season from 2015-19, though he didn’t take part in their run to the World Series last season. He made his final appearance with the Nats last Aug. 23, and the team designated him for assignment after that. The Diamondbacks then brought him in on a minor league deal in the offseason.
Grace struggled to a 6.36 ERA in 46 2/3 innings in his final season in Washington, but he did put up OK overall numbers during his time there. In all, he threw 176 1/3 frames of 4.29 ERA/4.04 FIP ball with 6.74 K/9, 2.5 BB/9 and a 53.4 percent groundball rate.
Chafin has been a quality reliever for the D-backs since his debut in 2014, but this season has not gone according to plan for the 30-year-old. He has already surrendered six earned runs on nine hits and four walks in 6 2/3 innings, and both lefties and righties have given him trouble so far.
