The Marlins have their guy locked up in ink. Second-round pick Ethan Kleinschmit, the Oregon State southpaw Miami took at No. 52 overall, officially signed for $1,892,500 - exactly full slot value, no drama, no games. That's the kind of quiet, business-as-usual transaction that doesn't make SportsCenter but matters a lot if you're a Marlins fan trying to figure out what this farm system looks like in 3 years.
Jim Callis broke the signing and laid out the scouting profile that made Kleinschmit worth full slot.
Callis's report is the whole story in a nutshell: outstanding feel, good deception, a low-90s fastball that misses bats thanks to carry, and a high-spin, low-80s sweeper that gives him a real weapon against both sides of the plate. That matches what scouts have said about him all spring - he's not a max-effort, triple-digit guy, he's a pitchability lefty who fills up the zone and lets deception and shape do the damage.
Kleinschmit's path here is a good underdog story before he's thrown a single pro pitch. He didn't come up through a flashy travel-ball pipeline - he started at Linn-Benton Community College in Albany, Oregon, before transferring to Oregon State, where he slid into the Beavers' rotation in 2025 and immediately looked like he belonged, striking out over 11 batters per 9 innings and holding hitters to a sub-.200 average.
As a junior he took the next step, going 9-2 with a 3.74 ERA across 77 innings, racking up 97 strikeouts against just 27 walks - the kind of strikeout-to-walk ratio that gets pro scouts circling a name on the draft board. That combination of missing bats and pounding the zone is exactly why a fastball that tops out in the 90s can still play as a legit weapon; command and shape matter more than radar-gun readings once you're pitching for a living.
Signing at full slot with no negotiation theater tells you the Marlins wanted this deal done and Kleinschmit wasn't looking to squeeze extra bonus pool money out of it. For an org that's leaned hard into scouting and developing pitching as its rebuild identity, adding a polished college lefty with a bat-missing fastball and a distinct breaking ball is a low-risk, high-feel add to a system that's going to need every arm like this if the big league roster is ever going to turn the corner.
Now it's about developmental reps - short-season ball to start, and watching whether that sweeper keeps its shape and the fastball ticks up an inch or two against better competition. Nobody's projecting him as a frontline starter off one clean junior year, but a lefty with feel, deception and two weapons that already miss bats is exactly the type of arm that's easy to root for as he moves through the low minors.
