The Orioles acquired right-handed reliever Miguel Castro from the Rockies on Friday, per a team announcement. Minor league right-hander Joe Gunkel was designated for assignment in order to clear space on Baltimore’s 40-man roster. The Rockies designated Castro for assignment on Sunday and will receive either cash considerations or a player to be named later.
Castro, 22, struggled in his sophomore season with the Rockies in 2016, spreading a 6.14 ERA, 3.1 BB/9 and 7.4 SO/9 over 14 2/3 inning. He looked even worse in Triple-A Albuquerque, handing in a 10.34 ERA after allowing 18 runs and five home runs in 15 2/3 innings. His high velocity and strikeout rate gave him a jump start on his major league career in 2015, but poor command continues to sabotage his performance on every level and could delay his promotion with the Orioles if he sees little improvement in their farm system this season.
According to MLB.com’s Brittany Ghiroli, Castro is scheduled begin the 2017 season at Double-A Bowie.
Update (12:58 AM ET): Per Henry Schulman of the San Francisco Chronicle, Samardzija has been diagnosed with a strained pectoral muscle. He’ll be shut down for a week. That’s good news for the Giants, considering the alternatives.
Giants starter Jeff Samardzija will undergo an MRI on his ailing right shoulder, according to NBC Sports Bay Area. The right-hander struggled in a minor league game on Wednesday, surrendering a pair of home runs and hitting a batter. Overall this spring, Samardzija has given up 15 runs (13 earned) on 17 hits (six homers) and seven walks with seven strikeouts in 11 innings.
This may mean Samardzija won’t be ready for the start of the regular season. Derek Holland would likely replace Samardzija in the rotation. Holland had been competing for the No. 5 spot in the Giants’ rotation.
Samardzija led the National League in losses last season with 15, also posting a 4.42 ERA with a 205/32 K/BB ratio in a league-high 207 2/3 innings. Since becoming a starter, Samardzija has been able to avoid injury, making 32 or 33 starts in each of the last five seasons.
