Mariners switch-pitcher Jurrangelo Cijntje is silently showcasing a key tool

Jurrangelo Cijntje recently returned to the Everett AquaSox after a 10-day reset and looked sharp as ever in his latest outing. The Seattle Mariners' switch-pitching prospect continues to showcase a unique set of skills, which apparently includes an ability to bounce back from injuries.

As reported by Seattle Sports 710, Cijntje missed time after tweaking his ankle, but came back strong after his injury. He threw 53 pitches, racking up six strikeouts and allowing one unearned run on three hits. He pitched left-handed just once and allowed a double.

Cijntje had previously been able to shrug off a minor issue with his right triceps, which MLB.com's Daniel Kramer reported was "vibrating" during his start on May 31. As much as the organization understandably wants to be cautious with his development, it is nonetheless encouraging to see him overcoming aches and pains and continuing to pitch well.

Jurrangelo Cijntje isn't letting minor injuries slow his 2025 breakout

The 22-year-old switch-pitcher is enjoying a strong season in Everett, posting a 4.28 ERA across 48.1 innings of work. He has made 11 starts and appeared as a reliever three times. It looks like the Mariners plan on stretching their 2024 first-round pick out as a starter. After struggling coming out of the bullpen, allowing nine earned runs in two innings, he holds a 2.72 ERA as a starter.

Cijntje's unique ability to throw from both hands is part of what has helped him climb prospect leaderboards, ranking among the MLB Pipeline's top 100 and the Baseball Prospectus top 100. So far this season, he has faced 165 batters as a right-handed pitcher and 40 as a left-handed pitcher.

His splits have been intriguing, as 48 of his 54 strikeouts have come from the right side. Meanwhile, five of the 13 extra-base-hits he's allowed have come from the left side.

Overall, Cijntje has been much more effective as a right-handed pitcher. Right-handed opponents are slashing .129/.193/.178 against him when throwing with his right arm, and left-handed batters are slashing .217/.357/.500.

On the other hand, Cijntje has struggled as a southpaw. Left-handed hitters have crushed him when he throws with his left arm, slashing .357/.654/.714 with two doubles, a home run and 12 walks in 26 plate appearances.

Control seems to be the issue when throwing with his left arm. He has issued 15 of his 28 walks as a left-handed pitcher, despite pitching left-handed about 20 percent of the time.

While the jury is still out on whether the Mariners' No. 8 prospect will be able to effectively throw with both arms going forward, it is clear Cijntje can dominate as a right-handed pitcher. As his development progresses, Mariners fans should watch Cijntje closely.
