The Rays made a corresponding move Wednesday, designating right-hander Trevor Martin for assignment to clear a 40-man roster spot for newly signed infielder Jorge Mateo. It's a quiet transaction on the surface, but it says a lot about how deep Tampa Bay's pitching staff has gotten this season and how ruthless the front office can be about roster math even in the middle of a division-leading run.
Martin only debuted in the majors this year, and it wasn't a smooth introduction. Across 11.1 relief innings for the Rays, he allowed 8 runs (5 earned) with 4 walks against 7 strikeouts, the kind of small-sample line that makes a bullpen spot easy to lose once a team needs the roster real estate for something else.
That something else is Mateo, a 31-year-old veteran who can slide in at shortstop, second or third base and gives the Rays more experience at the position than the younger Carson Williams, who was optioned as part of the shuffle. Mateo had just been designated for assignment and released by the Braves days earlier, so the move is a clear buy-low bet on utility depth heading into the stretch run.
For a team sitting atop the AL, this is the kind of transaction that barely registers outside of Tampa Bay's own fanbase, but it's exactly the churn that separates good rosters from great ones. The Rays have made a habit of squeezing value out of the margins of the 40-man, and Martin, for all his talent, became the odd man out once relief pitching became the position of greatest organizational depth.
Martin now has 10 days to clear waivers before the Rays have to figure out his next step, whether that's a trade, an outright assignment back to the minors, or losing him to another club looking for bullpen help. Either way, expect Tampa Bay to keep tinkering with the roster as they try to hold onto the league's best record down the stretch.
