The Arizona Diamondbacks are calling up left-hander Mitch Bratt (Newmarket, Ont.).

Nick Piecoro, of the Arizona Republic, was the first to report the transaction.

The Canuck lefty will be activated to start against the St. Louis Cardinals on Wednesday.

The move comes just two days after the D-Backs placed fellow Canadian Michael Soroka on the 15-day injured list with a glute strain.

Bratt, 22, has posted a 1-1 record and a 2.84 ERA in 11 starts for the triple-A Reno Aces this season. He has 42 strikeouts in 44 1/3 innings.

A Toronto Mets and Junior National Team alum, Bratt is in his second season in the D-Backs’ organization after being dealt to them by the Texas Rangers as part of the package for veteran right-hander Merrill Kelly at the trade deadline last year.

Selected in the fifth round of the 2021 MLB draft by the Rangers, Bratt pitched in parts of five seasons in the Rangers’ organization before joining the D-Backs.

In total, in 98 minor league appearances (89 starts), Bratt owns a 23-19 record and a 3.22 ERA. He has 492 strikeouts in 424 2/3 innings.

He was added to the D-Backs’ 40-man roster last November.
