The Pirates have signed right-hander Keury Mella to a minor league contract, reports Jake Crouse of MLB.com (Twitter link). He has been assigned to Triple-A Indianapolis. Mella was released by the Diamondbacks last week.
Mella has seen big league action in each of the past five seasons, albeit without ever carving out a consistent role on a staff. He’s never logged more than ten MLB innings in a given campaign, and his overall body of work consists of 28 2/3 frames of 7.22 ERA/5.11 SIERA ball. The 28-year-old made two appearances with the D-Backs this season, allowing six runs in 1 2/3 innings before being passed through outright waivers.
Over parts of four Triple-A campaigns, Mella has worked to a 4.55 ERA across 201 2/3 innings, starting a little more than half his appearances. He’s worked exclusively in relief this season, though, tossing 29 innings of 4.34 ERA ball in a hitter-friendly environment in Reno. Mella’s 22.7% Triple-A strikeout rate is a bit below-average, but he’s done well in avoiding walks and induced grounders on nearly half the balls in play against him.
In other Pirates roster news, the club activated left-hander Steven Brault from the 60-day injured list, as previously reported. He worked four innings of one-run ball against the Brewers this afternoon in his season debut. To create 40-man roster space, Pittsburgh transferred righty Chase De Jong from the 10-day to the 60-day injured list. De Jong is out for the season after undergoing surgery on his left knee last week.
