The Diamondbacks will recall Pfaadt from Triple-A Reno to start Friday against the Rays at Tropicana Field, Nick Piecoro of The Arizona Republic reports.
Pfaadt has been getting stretched back out during his time at Reno after he had been used in relief toward the end of his previous stint with Arizona. The right-hander threw 52 pitches over 3.2 innings in his last appearance with Reno over the weekend, so he will still be somewhat limited from a workload perspective Friday. Pfaaft should receive at least one additional start for the Diamondbacks after Friday while Ryne Nelson (elbow) and Michael Soroka (glute) remain on the injured list.
