Krehbiel's contract was selected by the Rays on Saturday, Neil Solondz of the Rays Radio Network reports.
Krehbiel made a pair of major-league appearances for the Diamondbacks in 2018 but has been in the minors ever since. He owns a 4.19 ERA in 43 innings for Triple-A Durham this season. He'll fill the roster spot left vacant by Kevin Kiermaier, who was placed on the COVID-19 injured list.
