The D-backs and the Rays both entered the major leagues in 1998. Arizona has the only World Series win, but Tampa Bay have been more successful in reaching the post-season, with ten playoff appearances to the D-backs’ seven. Overall, the win percentages of the teams are very similar. The D-backs are two points higher, at .495 against the Rays’ .493. But of late, our East coast siblings have definitely had the edge. In the past eight seasons, they have six trips to the post-season, to Arizona’s one. Over the same time-span, since the start of 2019, they have averaged 92 wins, a whopping fourteen victories per season more than the Diamondbacks.
That’s despite Tampa Bay having significantly less resources. From 2019-26 (and excluding 2020, for obvious reasons), Arizona had an average end of year payroll, per Spotrac, of $138 million. Tampa Bay’s mean salary bill was just $93 million. Here’s how the two teams have compared, year-by-year, in terms of salary, where that ranks in the majors, and their W-L record.
The Rays have spent one season outside the bottom quartile (25%) of team payrolls. The D-backs have been outside that six of the eight season, including a payroll in the top half, the past three years. Now, in 2024 and 2025, this did lead to the team winning nine and three more games than their siblings. But that run ended this year, with a vengeance. The Rays are in the World Series, while the Diamondbacks fell short of making the playoffs. Admittedly, had Arizona been in the American League, their 86 wins would have got them into the third wild-card. But that’s still a dozen games fewer than Tampa Bay.
So, what can the D-backs learn from the Rays? To try and get some idea, I want to start of by looking at the 26-man World Series roster for the Rays, and see how the team came to acquire each player. Below is the information on that, along with how valuable the player was for the Rays this year.
Pitchers
- Bryan Baker (2.9 bWAR) – Traded by the Orioles for pick #37 in the 2025 draft.
- Cam Booser (1.1) – Signed as a Free Agent.
- Garrett Cleavinger (-0.3) – Traded by the Dodgers for German Tapia.
- Griffin Jax (0.7) – Traded by the Twins for Taj Bradley.
- Kevin Kelly (1.9) – Purchased from the Rockies.
- Nick Martinez (3.9) – Signed as a Free Agent.
- Steven Matz (-0.7) – Signed as a Free Agent.
- Freddy Peralta (1.2) – Traded by the Mets for Gary Gill Hill, Émilien Pitre and Aidan Smith.
- Drew Rasmussen (4.7) – Traded by the Brewers with J.P. Feyereisen for Willy Adames and Trevor Richards.
- Ian Seymour (0.7) – Picked in the 2nd round of the 2020 draft.
- Cole Sulser (-0.3) – Purchased from the Mets.
- Tyler Wells (0.9) – Traded by the Orioles for Michael Forret.
The narrative would have you believe that the Rays’ success is due to strong drafting and a good farm system. But the above suggests otherwise – at least, directly (we’ll get into that eventually). Only one of the dozen pitchers on Tampa Bay’s roster for the World Series was drafted by them. Six were trades, with another two purchased, and three signed with the Rays as a free agent. But looking at the trades, it’s startling how little they generally had to give up. Willy Adames is easily the biggest name, and he was good for Milwaukee, putting up 14 bWAR over four seasons. But you think the Brewers wouldn’t rather have Drew Rasmussen, right now?
The Sulser thing is worth noting, because it was the third time the Rays had acquired him. He’s like their version of Ildemaro Vargas. They first did so in 2018, as part of a three-team trade which netted them Yandy Diaz. But they lost him on waivers the following October. Sulser was actually a Diamondback for a while, having been picked off waivers from the Marlins in November 2022. He played four games with Arizona, but was DFA’d in August 2023 and went back to Tampa, because we needed the roster spot for… Jace Peterson. Yeah. About that. Sulser hit free agency that winter, signed with the Mets but returned again to Tampa Bay the next July.
Catchers
- Nick Fortes (0.8) – Traded by the Marlins for Matthew Etzel
- Liam Hicks (0.7) – Traded by the Marlins for Jacob Kisting, Adrian Santana and Brayden Taylor.
I think it’s interesting that both Rays’ catchers came intrastate, by trades from their Florida neighbors. Fortes arrived at the trade deadline last year, and Hicks at the same point this season. Obviously, it’s impossible to judge these trades yet, since none of the four players sent to Miami have yet appeared in the majors. However, none of them were ranked higher than #16 in the Rays’ farm system at the time of the trade.
Infielders
- Jonathan Aranda (2.2) – Signed as an international Free Agent
- Junior Caminero (5.7) – Traded by the Indians for Tobias Myers.
- Yandy Díaz (2.4) – Traded as part of a 3-team trade by the Indians with Cole Sulser to the Rays. The Indians sent Edwin Encarnación and a 2019 competitive balance pick to the Mariners. The Mariners sent Carlos Santana and cash to the Indians. Rays sent cash to the Mariners and Jake Bauers to the Indians.
- Jorge Mateo (-1.0) – Signed as a Free Agent.
- Richie Palacios (1.8) – Traded by the Cardinals for Andrew Kittredge.
- Taylor Walls (3.5) – Picked in the 3rd round of the 2017 draft
- Ben Williamson (0.8) – Traded as part of a 3-team trade by the Mariners to the Rays. The Mariners sent Jurrangelo Cijntje, Tai Peete and a draft pick to the Cardinals. The Cardinals sent Brendan Donovan to the Mariners. The Rays sent Colton Ledbetter and a draft pick to the Cardinals.
We see the same pattern as with pitchers. Only one of the seven was formally drafted by the Rays. You could perhaps stretch to include Aranda, who was signed out of Mexico as a 17-year-old, and has never played with any other organization. But here, I note the lack of money spent on the free-agent market. Mateo was the only one in that category, and he was signed for a pittance after being cut by the Braves. He’s also basically a pinch-runner who didn’t get a PA in the first two playoff rounds. The only player earning more than seven figures on the Rays this year is Yandy Diaz, at a very reasonable $12 million. The Dodgers have twelve players there, if you include Ohtani. And you should.
The Caminero trade is likely going to go down as one of the greatest thefts in recent history. Caminero has been worth 10 bWAR for the Rays in 2025-26. Myers never appeared for the Ind…er, Guardians, and was last seen as a bad reliever in the Mets bullpen. The Diaz and Williamson deals, meanwhile, are both among those “How the heck did they work that out?“ situations. Bauers never amounted to much in Cleveland, before blossoming this year with Milwaukee, and will face his old team in the World Series. Again, Ledbetter was a prospect outside the top twenty in the Rays organization at the time of his trade.
Outfielders
- Jonny DeLuca (1.7) – Traded by the Dodgers with Ryan Pepiot to the Rays for Tyler Glasnow, Manuel Margot and cash.
- Victor Mesa Jr. (2.9) – Traded by the Marlins to the Rays for Angel Brachi.
- Cedric Mullins (1.0) – Signed as a Free Agent.
- Chandler Simpson (2.5) – Picked by the Rays in the 2nd round of the 2022 draft.
- Ryan Vilade (0.8) – Purchased from the Cincinnati Reds.
The trade which brought DeLuca to the Rays is an example of Tampa Bay selling high. Glasnow has been a bit of glass cannon for LA since: a 120 ERA+, but averaging fewer than 18 appearances per season. Pepiot was almost as good as Glasnow in 2024-25 – certainly more durable – and considerably cheaper. But he missed all of this season with a hip issue. Brachi was unranked by MLB Pipeline when he was dealt: I’m beginning to detect a theme here. But again, we see a limited number of players who were actually drafted by Tampa Bay. They seem keen on, and adept at, plucking players they need away from other teams.
Summary
- Trades: 14 players
- Signed as a free agent: 5 players
- Purchased: 3 players
- Draft pick: 3 players
- International free agent: 1 player
This certainly demonstrates where the strength of the Rays lies. As mentioned, it’s not directly in the draft, with barely ten percent of their World Series roster having been acquired that way. It’s in smart trades, purchases and low-cost free-agent signings – or what’s often derided when Mike Hazen does it, as “dumpster diving.” Of course, that’s the kind of thing that’s easier said than done, though the Arizona bullpen this season shows that it is something Hazen can figure out on occasion. It’s an interesting contrast to the Brewers, who have a much more internal approach to their roster: seven draftees and three international free agents.
But we shouldn’t write off the Tampa Bay farm system entirely. Next time, we’ll take a look at that and see if we can figure out how it plays into the team’s strategy.
