	Schultz competed for a spot on the Diamondbacks' Opening Day roster in spring training in 2014. With the ability to carry ten relievers on the roster for a two-game series against the Los Angeles Dodgers in Sydney, Australia, he was named to their Opening Day roster, with the expectation that the Diamondbacks would assign him back to Triple-A after the series. He made his MLB debut on March 22, 2014. Schultz made four relief appearances for the Diamondbacks in 2014, pitching to a 0–1 record, 7.88 ERA, and five strikeouts in eight innings. In Triple-A that year, Schultz would post a 10–8 record with a 6.18 ERA and 82 strikeouts in a career-high 135 innings.
