A’s Agree To Minor League Deals With Nick Martini, Aaron Brooks

By Steve Adams | June 6, 2025 at 2:13pm CDT

The A’s have agreed to minor league deals with a pair of old friends, signing outfielder Nick Martini and righty Aaron Brooks, per the transaction log at MLB.com. Martini has been assigned to Triple-A and Brooks to Double-A.

Martini, 34, was recently designated for assignment by the Rockies and elected free agency after clearing waivers. He inked a minor league deal with Colorado over the winter and broke camp with the Rox after an excellent showing in spring training. However, Martini struggled greatly in 111 plate appearances, despite taking only five left-on-left turns at the plate and despite playing his home games at Coors Field. He slashed .225/.288/.294 during his time in purple — a tepid follow-up to a similarly rough showing with the 2024 Reds (.212/.272/.370 in 163 plate appearances).

Rough as Martini’s 2024-25 seasons have been, he’s only a season and a third removed from batting .264/.329/.583 in 79 plate appearances with Cincinnati. That was the final season of a limited but productive six-year stretch that saw the lefty-swinging walk machine bat .268/.362/.412 while drawing a free pass in 11.2% of his plate appearances. Martini regularly posts gaudy walk rates in the minors and has had little trouble frequenting the basepaths in Triple-A, as evidenced by his career .294/.399/.454 slash in parts of eight seasons at the top minor league level.

Brooks, 35, opened the 2025 season with el Caliente de Durango in the Mexican League. He’s posted an unsightly 5.92 ERA in 38 innings so far, although in the supercharged run-scoring environment of that league, a 5.92 mark is actually a slight bit better than the 5.99 league average. Brooks has fanned only 14.6% of his opponents but also touts a sharp 4.6% walk rate.

Brooks pitched for the A’s just last season — his third stint with the A’s dating all the way back to the time he was traded to Oakland alongside Sean Manaea in a deal that shipped Ben Zobrist to the eventual 2015 World Series champion Royals. Last year, Brooks tossed 26 2/3 big league innings and logged a 5.06 ERA with a similarly poor strikeout rate (10.1%) and strong command (6.7% walk rate).

If he ends up back in the majors, Brooks will be in his seventh season with at least some big league time. He’s totaled 206 2/3 innings in the majors and logged a 6.36 ERA, a 15.3% strikeout rate and a 6.8% walk rate between the Royals, A’s, Orioles and Cardinals. In addition to that MLB work, Brooks enjoyed a strong two-year run in the Korea Baseball Organization and has pitched a 4.65 ERA in 720 Triple-A innings.

The A’s have five starting pitchers on the injured list and have seen healthy rotation candidates like Osvaldo Bido and Joey Estes pitch poorly in 2025. Brooks is hardly a high-ceiling addition, but he’ll give them some more depth. On the position-player side of things, the A’s have Miguel Andujar on the IL, have already passed Seth Brown through waivers (though he’s reportedly coming back today), and recently optioned a struggling JJ Bleday to Triple-A (though he’s since been recalled). Martini gives them an experienced option to stash in Triple-A.

    Whoa! that’s a name from a long ago Baltimore roster. I had no idea Brooks was still making a go of it. Best wishes, Aaron. My favorite part of this post is that 5.99 is the league average ERA for the Mexican League. maybe the O’s can sign some pitchers from the Mexican League. They have done well with Miguel Gonzo and Albert in the past.

    Brooks literally couldn’t cut it in the Mexican League…
    Martini wasn’t good enough to stick with Colorado…

    “Rough as Martini’s 2024-25 seasons have been” is NOT PROPER ENGLISH. You can’t just leave “as” out to begin the sentence. It’s not optional! Grammar is not optional when you’re being paid to write.
