Update (5:36 PM ET, Bill Baer): Rosenthal will undergo Tommy John surgery, per MLB.com’s Jenifer Langosch. That’ll knock out most of his 2018 season at minimum.
Cardinals closer Trevor Rosenthal is done for the season as the Cardinals have transferred him from the 10-day to the 60-day disabled list.
He had originally been placed on the 10-Day DL last Thursday with “elbow irritation” and “arm tightness” but it’s obviously more than a mere irritation. He has seen two specialists in the past week and, while the team has not given word as to his official diagnosis, both specialists are Tommy John guys, which suggests that major elbow surgery is in the offing for Rosenthal.
Rosenthal finishes the year at 3-4 with a 3.40 ERA and a K/BB ratio of 76/20 in 47.2 innings with 11 saves. He had lost the closer’s job heading into the year but had regained it before going down. Going forward, some combination of Seung Hwan Oh, Tyler Lyons, and John Brebbia will fill cover the end of games as the Cardinals try to climb back into the playoff picture.
On Friday evening, Major League Baseball and the MLB Players Association announced the first set of results for COVID-19 testing as part of the mandatory intake screening process under MLB’s COVID-19 Health Monitoring & Testing Plan. Per Susan Slusser of the San Francisco Chronicle, the Athletics are not part of this data because their testing has not yet been completed.
There were 38 positive tests, accounting for 1.2% of the 3,185 samples collected and tested. 31 of the 38 individuals who tested positive are players. 19 different teams had one or more individuals test positive.
Sports Illustrated’s Emma Baccellieri notes that the positive test rate in the U.S. nationally is 8.3 percent. The NBA’s positive test rate was 7.1 percent. MLB’s positive test rate is well below average. This doesn’t necessarily mean that anything is wrong with MLB’s testing or that it’s an atypical round of testing. Rather, MLB’s testing population may more closely represent the U.S. population as a whole. Currently, because testing is still somewhat limited, those who have taken tests have tended to be those exhibiting symptoms or those who have been around others who have tested positive. If every single person in the U.S. took a test, the positive test rate would likely come in at a much lower number.
Several players who tested positive have given their consent for their identities to be made known. Those are: Delino DeShields (link), Brett Martin (link), Edward Colina, Nick Gordon, and Willians Astudillo (link). Additionally, Red Sox lefty Eduardo Rodríguez has not shown up to Red Sox camp yet because he has been around someone who tested positive, per The Athletic’s Jen McCaffrey.
