Marlins Select Luis Madero, Option Daniel Castano

By Anthony Franco | May 9, 2021 at 9:55am CDT

The Marlins are selecting the contract of right-hander Luís Madero, Jordan McPherson of the Miami Herald was among those to relay (Twitter link). Lefty Daniel Castano was optioned to Triple-A Jacksonville, while right-hander Jorge Guzman was transferred to the 60-day injured list to clear 40-man roster space.

Madero has bounced between a few organizations in his pro career but has yet to make his MLB debut.  Originally signed by the Diamondbacks as an international amateur, he was sent to the Angels at the 2017 trade deadline for reliever David Hernández. Madero eventually worked his way onto Los Angeles’ 40-man roster and was named the #19 prospect in the organization entering the 2019 season by Baseball America. He struggled at Double-A that year, though, working to a 5.72 ERA in a pitcher-friendly environment. The Angels designated him for assignment and lost him on waivers to the Giants after the season.

San Francisco passed Madero through waivers shortly thereafter, and he spent the 2020 season at their alternate training site. He didn’t make it back on the roster and wound up electing minor-league free agency. Miami signed Madero to a minors deal in January, and he’s earned a major league call after just one Triple-A appearance. Madero has plenty of starting experience in the minors, so he offers rotation and/or long relief depth for the Fish. The 24-year-old still has a pair of option years remaining, so he can be sent back-and-forth between Miami and Jacksonville if he keeps his spot on the 40-man.

Castano, 26, has started four games for the Marlins this year but hasn’t found much success. The soft-tossing lefty has been knocked around for a 5.19 ERA/5.47 SIERA over 17 1/3 innings. Castano prevented runs at a strong clip over seven games last season, but his peripherals always suggested that was unlikely to continue. He simply hasn’t missed enough bats to establish himself as a big league starter, compiling a minuscule 10.8% career strikeout rate.

Guzman, one of the Marlins’ better pitching prospects, has been battling elbow inflammation. General manager Kim Ng told reporters in March he’d be “out for a bit,” so it’s not particularly surprising to see him wind up on the 60-day IL.

    Disappointing to see Guzman injured again. I think Miami needs to stop hoping he’d be a starter and dedicate him to being a relief pitcher.. I’ve always envisioned him as the teams future setup man/closer.

    Castano wakes up shaking in a deep sweat thinking of Adrian Houser every night in his sleep.

    Does he know that his beard is uneven? I can’t unsee this.
