The Oakland A's placed outfielder Mark Canha and right-handed pitcher Liam Hendriks on the 15-day disabled list, optioned right-handed pitcher J.B. Wendelken to Triple-A Nashville, recalled right-handed pitcher Andrew Triggs and utilityman Tyler Ladendorf, and selected the contract of left-handed pitcher Daniel Coulombe from Nashville, the club announced today.
 
To make room for Coulombe on the 40-man roster, right-handed pitcher Chris Bassitt was transferred to the 60-day disabled list.
 
Canha was placed on the DL with a back strain and Hendriks has a right triceps strain. Hendriks' stint on the disabled list is retroactive to May 8 while Canha's is retroactive to May 9.
 
This will be Triggs' fourth stint with the A's this season, Ladendorf's second, and Coulombe's first.
