Orioles' Isaac Mattson: Healthy at Triple-A
Rotowire
Mattson (shoulder) has made three relief appearances for Triple-A Norfolk this season, covering three no-hit scoreless innings while striking out three and issuing one walk.
Mattson dealt with a sore right shoulder in spring training, which closed the door on any outside chance he had for making the Orioles' Opening Day roster. After being outrighted off the 40-man roster April 8, Mattson will face an even tougher time making it back in the big leagues even though he's now healthy again.

Orioles' Isaac Mattson: Delayed by sore shoulder
Rotowire
Mattson is a month behind schedule due to shoulder soreness, Roch Kubatko of MASNSports.com reports.
Mattson isn't expected to get on a mound until April and will still have weeks of buildup to do at that point, so he'll almost certainly open the season on the injured list. The 26-year-old made his big-league debut last season but threw just 4.1 innings, so he's not necessarily in line for a significant role once he gets healthy.

One of the pitching prospects that Baltimore received from the Angels in last offseason's Dylan Bundy trade, Mattson spent the summer at the alternate training site. He is a relief pitcher and struck out 19 in 9.1 innings at Triple-A in 2019, so he could eventually work in high-leverage situations.

Orioles' Isaac Mattson: Joins player pool
Rotowire
Mattson was added to the Orioles' 60-man player pool Friday, Roch Kubatko of MASNSports.com reports.
Mattson will give the Orioles' additional pitching depth, but he's not on the team's 40-man roster, so he shouldn't be expected to fill a large role. He's only thrown 9.1 innings at the Triple-A level, though he did strike out 19 batters over that brief stretch, hinting at his potential.
