Castro (knee) is expected to toss a bullpen session Tuesday, Roch Kubatko of MASN Sports reports.
Castro was scratched ahead of his scheduled Grapefruit League start Sunday due to tendinitis in both knees. He received treatment on the knees, as well as his lower back, and stated that he wasn't too concerned about either ailment. If all goes well with Tuesday's bullpen, Castro will likely take the mound in a spring game later next week.
Castro will miss his Grapefruit League start Sunday, Brittany Ghiroli of MLB.com reports.
Castro is dealing with both tendinitis in his knees and a sore back. It doesn't sound like he'll be out long, though he's in competition with Gabriel Ynoa and Mike Wright for the Orioles' fifth starter job and his chances could be hurt if he does end up missing several starts this spring.
The tall right-hander spent the last three seasons as a reliever, but the Orioles want to see what he can do as a starter given their lack of depth at the position. Castro had a decent campaign with the Orioles last season, producing a 3.53 ERA in 38 relief appearances and one start, but his peripherals raise many concerns. He hasn't struck out many batters in the majors (6.2 K/9 over the last three seasons), he walks too many hitters (3.9 BB/9 in that span) and his FIP last season was nearly a point and a half higher than his ERA. Gabriel Ynoa and Mike Wright will also be vying for a rotation spot this spring, so Castro will need to impress during Grapefruit League play if he wants to nab the role for himself.
He hasn't thrown yet at the Orioles' pitching minicamp, but is preparing to make the transition from reliever to starter. Once a high-upside pitching prospect for the Blue Jays earlier this decade, Castro was moved to the bullpen to expedite his ascent to the majors, and was then shipped to Colorado in the Troy Tulowitzki deal. He joined the Orioles last season and logged a 3.53 ERA, 1.22 WHIP and 38:28 K:BB in 66.1 innings, making 38 of his 39 appearances out of the bullpen. While he didn't record many strikeouts, his fastball and slider can be quality pitches, and his changeup is passable. The key for the 23-year-old righty will be holding up physically with an increased workload, as his 90.2 innings between Double-A and the majors last season marked a career high. The Orioles might have the worst starting pitching depth in the American League, so Castro has a good shot to win a rotation spot, making him a worthwhile target in deep formats.
Castro (3-3) took the loss Saturday, giving up three runs on six hits and one walk over 3.1 innings against the Rays. He struck out three.
Things were going pretty well for Castro in his first career big-league start up until the fourth inning; he allowed three straight hits to begin the frame, including a homer to Brad Miller. Castro was traded to the Orioles early in the year after being designated for assignment by the Rockies and went on to post strong ratios, but his strikeout rate fell off a cliff in his age-22 season.
