KBO’s Kiwoom Heroes Sign Kenny Rosenberg
The Kiwoom Heroes of the Korea Baseball Organization announced their trio of foreign-born players for the 2025 season. The Heroes signed outfielders Yasiel Puig ($1MM) and Ruben Cardenas ($450K salary with $150K in incentives) and left-hander Kenny Rosenberg ($700K salary with $100K in incentives). The deals were relayed (on X) by Dan Kurtz of MyKBO.net.
Rosenberg is the only one of the trio who appeared in the majors in 2024. The 29-year-old southpaw pitched in seven games for the Angels, allowing an even 6.00 ERA across 24 innings. It was the third straight season in which Rosenberg made a handful of appearances for the Halos. He worked as a depth option for the rotation or low-leverage relief and combined for a 4.66 mark over 67 2/3 frames.
Los Angeles released Rosenberg within the first few days of the offseason. This will be the first overseas stint for the Cal State Northridge product. Rosenberg had previously split his eight-year professional career between the Rays and Angels organizations. He has a solid Triple-A track record. Over parts of five seasons at the top minor league level, he carries a 4.10 ERA while striking out a quarter of opposing hitters.
Puig hasn’t appeared in the majors since 2019. He played the 2022 season in Korea with the Heroes. Puig spent the ’24 campaign in Mexico. Cardenas spent most of this this year in Triple-A. He divided his time between the Rays’ and Phillies’ systems but didn’t get a big league call. He signed with the KBO’s Samsung Lions late in the year but only made seven appearances. The Cal State Fullerton product should get a more significant opportunity for the Heroes.
KBO’s Samsung Lions Sign Lewin Diaz
The Samsung Lions of the Korea Baseball Organization announced this week that they’ve signed first baseman Lewin Díaz (relayed on X by Dan Kurtz of MyKBO). The CAA Sports client receives a $50K salary with up to $20K in incentives for the stretch run. The Lions also paid a $100K release fee to the Diablos Rojos del Mexico, the Mexican League team with which Díaz had been playing. Samsung waived outfielder Ruben Cardenas in a corresponding move.
Díaz, 27, was an MLBTR staple during the 2022-23 offseason. He changed teams via waivers or minor trade four times that winter. The Orioles eventually succeeded in sneaking him through waivers and kept him in Triple-A for all of last season. Díaz had a decent year in the minors, hitting .268/.362/.442, but never got an MLB look from Baltimore. He qualified for minor league free agency over the winter and signed a non-roster deal with the Nationals.
Washington released Díaz at the end of camp. He didn’t land another affiliated deal, instead making the move to Mexico. The left-handed hitter has mashed at a .376/.452/.647 clip with 19 homers across 75 games in that very hitter-friendly league.
Díaz was a fairly well-regarded prospect with the Twins early in his pro career. Minnesota dealt him to the Marlins as part of a deal for reliever Sergio Romo in 2019. Díaz didn’t hit major league pitching over parts of three seasons in Miami, running a .181/.227/.340 slash in 112 games. He has been an above-average Triple-A batter, posting a .258/.341/.479 mark in nearly 1200 plate appearances at the level.
Phillies Acquire Ruben Cardenas From Rays
2:03pm: The Rays have made it official, announcing that they have traded Cardenas to the Phillies for cash considerations.
12:56pm: The Phillies have acquired minor league corner outfielder Ruben Cardenas from the Rays, reports Kiley McDaniel of ESPN on X. Cardenas wasn’t on Tampa’s 40-man roster and therefore won’t require a roster spot with Philadelphia. It’s not known what the Rays will receive in return but small trades involving minor leaguers often involve cash considerations going the other way.
Cardenas, 26, was a sixth-round selection of Cleveland in 2018 but went to the Rays a year later. Prior to the 2019 deadline, he was traded to Tampa along with international bonus pool space, as Hunter Wood and Christian Arroyo went the other way.
He’s been climbing the minor league ladder since then, generally providing a bit of power but also striking out a fair bit. He split 2021 between High-A and Double-A, hitting 25 home runs in 441 plate appearances but also striking out 26.1% of the time and only walking at a 5.4% clip.
He got to Triple-A in 2022, getting into 82 games at that level. He hit 16 home runs and improved his walk rate to 10.1% but was also punched out 29.2% of the time and slashed .208/.289/.440 for wRC+ of 89. Returning to Triple-A last year resulted in slight improvements: 22 home runs in 132 games, an 11.3% walk rate, 26.4% strikeout rate, .269/.358/.475 batting line and 108 wRC+.
Back at Triple-A in 2024, he has lowered his strikeout rate to 21% but has only walked 5.9% of the time. The power is still present, as he has 11 home runs in just 49 games this year, leading to a .281/.346/.530 line and 121 wRC+. Cardenas has never been a highly-touted prospect but did get an honorable mention from FanGraphs on their lists of Rays prospects in 2022 and 2023.
The Phillies recently lost outfielder Brandon Marsh and infielder/outfielder Kody Clemens to the injured list, subtracting their position player depth a bit. That’s prompted them to call up the oft-injured David Dahl to play alongside a struggling Nick Castellanos and their glove-first center fielder Johan Rojas. They’ve also given some brief outfield playing time to Cristian Pache and Whit Merrifield, who aren’t hitting much this year.
Though the Phillies are tied with the Yankees for the best record in baseball, the outfield is a relative weak part of the roster and Cardenas will give them a bit of extra depth there without taking up a roster spot. The Rays, however, have an outfield mix consisting of Randy Arozarena, Josh Lowe, Richie Palacios, Jose Siri, Jonny DeLuca and Harold Ramírez. Also, infielder Taylor Walls has begun a rehab assignment and could rejoin the club soon, which could push Amed Rosario from the dirt to the grass/turf. Cardenas would have been challenged to find playing time in Tampa so they have sent him to Philly instead for what is likely a bit of cash.
