Minor MLB Transactions: 9/12/21

Some minor moves from around the league:

• The Marlins have released left-hander Ross Detwiler, according to the MLB.com transactions page. Detwiler had been designated for assignment on Tuesday. The release is largely a formality, as Detwiler had the ability to reject an outright assignment. The 35-year-old will now see if there are any offers available for him on the open market. He would not be eligible to appear in the playoffs with any new club, since it is after the August 31st deadline. But he could potentially help a team absorb some innings down the stretch. In 45 1/3 innings this year, he has an elevated ERA of 4.96. However, his 28% strikeout rate is a career high, though that’s also come with a career-low ground ball rate of 39.7%.
• The Cardinals reinstated minor-league righty Johan Quezada from the 60-day injured list, according to a team announcement. Right-hander Junior Fernandez is going the other direction, landing himself on the 60-day injured list, according to Jeff Jones of the Belleville News-Democrat. Quezada was acquired from the Phillies in the offseason but hasn’t been able to pitch much this year due to injuries. The 27-year-old has thrown 16 2/3 innings between the Florida Complex League and Double-A. As for Fernandez, this IL placement will end his season. He racked up a lot of mileage shuttling between Triple-A and MLB this year, being recalled and optioned five times. He’ll finish the season with an ERA of 5.66 over 20 2/3 innings in the big leagues, along with identical strikeout and walk rates of 15.5%. In 14 1/3 Triple-A innings, his ERA is higher, 6.28, but with much better strikeout and walk rates of 33.3% and 7.6%, respectively.
