Diamondbacks Pitcher Justin Martinez Throwing Again After Surgery

The young pitcher who captured hearts with his blazing fastball and devastating splitter is proving that setbacks don't define careers.

Justin Martinez, the Arizona Diamondbacks' rising star closer, shared an Instagram video this week showing himself throwing at the team's training complex in Phoenix. While he wasn't hitting his usual triple-digit speeds, the simple act of throwing again marks incredible progress for a pitcher who underwent Tommy John surgery just seven months ago.

The right-hander's 2025 season ended abruptly on June 9 when he felt tightness in his elbow during a game against the Seattle Mariners. After being diagnosed with a UCL sprain, Martinez faced the reality that haunts every pitcher: season-ending elbow reconstruction surgery.

Before the injury struck, Martinez was emerging as one of baseball's most exciting young relievers. He recorded five saves and struck out 22 batters while handling high-pressure closing situations for Arizona. His power arm made him a fan favorite and a cornerstone of the team's bullpen plans.

Why This Inspires

Martinez's recovery timeline is ahead of schedule for most Tommy John surgeries, which typically sideline pitchers for 12 to 18 months. Seeing him throw just seven months post-surgery offers genuine hope that he could return to competitive action sooner than expected.

His comeback matters beyond just one team's pitching depth. Young athletes recovering from serious injuries need to see examples of patience and steady progress paying off. Martinez isn't rushing his rehabilitation or pretending to be at full strength yet, and that measured approach speaks volumes.

The Diamondbacks clearly felt Martinez's absence down the stretch last season, cycling through a record-breaking 17 different pitchers to record saves. His return would restore stability to a bullpen that desperately needs it.

For now, Martinez continues his careful progression back to full health, working daily at the team's complex and documenting his journey for fans who've supported him through the tough times.

One casual throwing session might not seem like much, but for a pitcher seven months removed from major surgery, it's everything.
