Minor MLB Transactions: 5/9/17

Here are the day’s minor moves:

• Angels lefty John Lamb has received a fifty-game suspension for his second positive test for a drug of abuse, as Mike DiGiovanna of the Los Angeles Times was among those to tweet. The 26-year-old received 24 MLB starts over 2015-16 with the Reds, who acquired him in the Johnny Cueto deal. But he struggled to a 6.17 ERA in that span, striking out 8.7 batters per nine while issuing 3.8 walks per nine and allowing 142 base hits — 22 of them long balls. Lamb caught on with the Halos on a minors deal after he was cut loose by Cincinnati over the winter.
• The Dodgers have inked lefty Logan Darnell to a minors pact, as Triple-A Oklahoma City broadcaster/media relations director Alex Freedman announced on Twitter. Darnell, 28, has 24 MLB frames under his belt, all of those coming in 2014 with the Twins. Last year, he worked to a 3.53 ERA over 109 2/3 Triple-A frames. He wasn’t exactly generating great results with the indy ball Somerset Patriots, but evidently showed enough to catch the eye of the Dodgers’ brass.
• Righty Justin De Fratus has signed a minor-league deal with the Mariners, the indy ball Southern Maryland Blue Crabs announced on Twitter. De Fratus, 29, spent parts of five years in the majors with the Phillies. But he struggled in 2015 and then bounced around the minors last season.
• The Cardinals have released reliever Mitch Harris, as Glenn Sattell of MLB.com reports. The 31-year-old has continued to struggle with elbow issues. He had made a notable big league debut in 2015, making it to the majors after putting his professional career on hold during a stint in the Navy. The Naval Academy grad worked 27 innings of 3.67 ERA ball that year, though he managed only 5.0 K/9 against 4.3 BB/9 in that stretch.
