The Dodgers selected the contract of left-handed pitcher Ronan Kopp. That’s their only move for Tuesday’s Rule 5 protection deadline. L.A. had two openings on the 40-man roster and didn’t need to make a corresponding move.
Kopp, 23, is a reliever who divided the 2025 season between Double-A Tulsa and Triple-A Oklahoma City. He turned in a combined 3.43 earned run average across 57 2/3 innings. Kopp fanned a massive 36% of opposing hitters but walked almost 17% of the opponents he faced. He has a mid-90s fastball and a cutter-slider that he used almost equally in Triple-A.
It’s plus stuff with obvious command woes from the left side. Neither left nor right-handed hitters could do much damage against Kopp, but they each reached base around a .350 clip by waiting out the free passes. While he’ll need to dial in the command, the Dodgers obviously feel he’s talented enough to factor in as bullpen depth in 2026. He joins Alex Vesia, Tanner Scott, Justin Wrobleski, Jack Dreyer and Anthony Banda as lefty relievers on the 40-man roster.

Dodgers are ruining baseball by keeping marginal relievers hoping their upside will come to the forefront.
So said Ronan the Accuser!
Duuuude…that’s going Silver Age deep. 1st appearance FF#65 late ’60’s. Haven’t kept up on the televised end but assuming he’s been featured in the recent films/series at some point.
Also Guardians of the Galaxy movie released August 2014.
…Or
It’s a dystopian future where a lone cop is the only survivor after his whole precinct is wiped out. No longer with a captain, he roams the country side with only a side arm and his trusty K9 pal Rusty, bringing justice to an unjust world any way they can.
You had me at, ‘trusty K9 pal Rusty’.
I’m a Kopp, you idiot!
Said in your best David Harbour Boston accent
No, it’s Detective John Kimble (aka, Arnold).
I am guessing that Peter Heubeck wll be picked in Rule V.
And Dodger F/O is OK with it
Apparently
So, with the addition of Kopp, what they gonna do with Landon Knack & Bobbie Miller?
They’re both on the 40 man. Knack will toil for another season in 26th-man purgatory. Miller will be prayed over by the Dodgers resident shaman before either emerging restored to prospect status or given his last rites.
Kopp, a lefty reliever, doesn’t have much to do with Knack and Miller – righty starters (Miller might just be a reliever now)
Good Kopp or bad Kopp?
Finally, a Dodgers post! It’s like MLBTR doesn’t know this team exists! 😀
Maybe his parents watched too much anime. If he ever makes it to the big club some of his teammates are going to have a lot fun with his name.
