The St. Louis Cardinals have finally traded Brendan Donovan away to complete their offseason fire sale.

In return, they get one of the most intriguing prospects in baseball, switch-pitcher Jurrangelo Cijntje, a former first-round pick.

That’s one of two reported players going to St. Louis in the deal, via the Seattle Times’ Adam Jude, along with 2023 first-round pick Tai Peete, an outfielder

Cijntje is the prize here.

He pitched his first professional season in 2025, and the Mariners had him alternate outings, one righty, one lefty, for most of the season.

By the end, he focused mostly on his right-armed pitching, a side from which he has better stuff and put up better numbers.

The Mariners were already saying this spring they played to just have Cijntje throw right-handed in games while letting him be a southpaw in the bullpen.

Cijntje has much stronger stuff with his right arm, both a harder fastball and better breaking pitches.

In the minor leagues in 2025, batters hit .198 off the right-handed Cijntje and .289 off the left-handed Cijtnje.

The Cardinals will get to decide if they have the same thought as Seattle or if they’d like to see Cijntje keep the switch-pitching uniqueness going.
