Adrian Morejon took the mound Tuesday for his first big league appearance of 2020 and his first appearance in a live game -- either the Majors or the Minors -- in over a year. But after his performance, the left-hander probably won’t have to wait long to see the mound again.

The Padres’ seventh-ranked prospect dealt three hitless frames as the starting pitcher in their 6-4 victory over the Rangers at Globe Life Park. He struck out four and walked one, the lone blemish on his otherwise spotless day.

Morejon hadn’t recorded a pitch since last Aug. 6 after a shoulder injury sent him to the Injured List and eventually led to him being shut down for the year. But he’d been working out at the team’s alternate site at the University of San Diego since the season began, and according to Padres skipper Jayce Tingler, likely isn’t heading back soon.

"All I know is this: He continues to throw the ball like that, there will be roles for him, whether that's coming out of the 'pen or another start," Tingler told MLB.com. "Because that's exactly what we needed. That was power stuff, that was swing-and-miss, that was aggressive, that was a good tempo. It was everything we're looking for."

Morejon hit the ground running, striking out Shin-Soo Choo and Danny Santana back-to-back to start the bottom of the first inning. He retired three more before issuing a free pass to Isiah Kiner-Falefa, but got Derek Dietrich to ground out to end the inning. In the third, the 21-year-old struck out Scott Heinemann and induced groundouts from Jeff Mathis and Choo to cap his start.

The outing was Morejon’s sixth in The Show -- he made two starts and three relief appearances in 2019. His second go-around has gotten off on a better foot, he posted a 10.13 ERA last season after allowing nine runs in eight innings.

Over five years in the Minors, Morejon logged a 3.78 ERA across five different levels. He never pitched at Triple-A, posting a 4.25 ERA over 16 starts with Double-A Amarillo in 2019 before getting called to the Majors in July.

Following Morejon was San Diego's No. 27 prospect Javy Guerra, who was pegged for four runs -- three earned -- without recording an out in the fourth. Veteran Craig Stammen steadied the ship with two one-hit frames to set up third-ranked Luis Patiño, who walked three and struck out one in the sixth, but escaped unscathed and without allowing a hit.

Offensively, No. 19 Jake Cronenworth stayed red-hot season by going 2-for-3 with a double, a walk and a run scored. The rookie is batting .321/.387/.607 on the year.

No. 26 Rangers prospect Jonathan Hernández threw a perfect eighth, striking out two. His ERA sits at 1.28.
