Alexander was recalled from Triple-A Omaha on Thursday, Rustin Dodd of the Kansas City Star reports.
The left-handed Alexander has spent the whole 2016 campaign at Triple-A to this point, allowing three earned runs over 14.0 innings of work out of the bullpen. He'll add a fresh arm to a bullpen that has been taxed of late thanks to short starts from Chris Young (forearm) and Kris Medlen (shoulder)--both of whom have since been placed on the disabled list.
