Cubs: Selected the contract of LHP Clayton Richard from Class AAA Iowa and placed C David Ross on the seven-day concussion disabled list. Also selected C Taylor Teagarden’s contract from Iowa, optioned RHP Donn Roach to Iowa and designated RHP Gonzalez Germen for assignment.
Diamondbacks: Activated LHP Patrick Corbin (Tommy John surgery) and C Oscar Hernandez from the 60-day disabled list. To make room, Arizona optioned UT Danny Dorn and RHP Matt Stites to Class AAA Reno.
Tigers: Slugger Miguel Cabrera will be sidelined for at least six weeks after Detroit placed the AL batting leader on the disabled list for the first time in his career with a strained calf. To replace him, the team selected the contract of 3B Jofry Marte from Class AAA Toledo.
Twins: Reinstated RHP Ervin Santana following an 80-game drug suspension and optioned RHP Alex Meyer to Class AAA Rochester.
Yankees: Closer Andrew Miller, who has not pitched since June 9 because of a strained left forearm, threw 30 pitches in a bullpen session and could soon return.
