By the end of this post, you’ll have a better understanding of what happened to Diego Castillo and how it impacted the Rays and Mariners.
Who is Diego Castillo?
Diego Castillo is a 27-year-old right-handed relief pitcher who was born in Cabrera, Dominican Republic. He was signed as an international free agent by the Tampa Bay Rays in 2014 and made his major league debut with the team in 2018.
Castillo quickly established himself as a reliable bullpen arm for the Rays, and he played a key role in their success over the past few years.
Before the trade, Castillo had pitched in 38 games for the Rays during the 2021 season, recording 14 saves with a 2.72 ERA and 35 strikeouts in 36 1/3 innings pitched.
He had a reputation as a hard-throwing pitcher with a nasty slider and excellent control, making him a formidable presence on the mound. Castillo’s success as a reliever was a major reason why the Rays were in contention for a playoff spot at the time of the trade.
Throughout his career with the Rays, Castillo had pitched in 166 games, recording 25 saves with a 3.29 ERA and 202 strikeouts in 172 innings pitched. He was known for his ability to induce ground balls and limit home runs, making him an effective pitcher in high-pressure situations.
Castillo had also made appearances in the postseason with the Rays, helping them reach the World Series in 2020. Overall, he was a valuable member of the Rays’ bullpen and a fan favorite.
The Trade
On July 29, 2021, just before the MLB trade deadline, the Tampa Bay Rays traded Diego Castillo to the Seattle Mariners in exchange for two players, J.T. Chargois and Austin Shenton.
The trade came as a surprise to many fans and analysts, as Castillo was a key player for the Rays and had been pitching well during the 2021 season.
The trade was reportedly motivated by several factors. One reason was financial, as Castillo was set to become arbitration-eligible after the 2021 season, and the Rays may have been unwilling to pay his expected salary.
Additionally, the Rays had a surplus of bullpen arms, and they may have felt that they could afford to trade Castillo and still have a strong bullpen.
The Mariners, on the other hand, were in need of bullpen help, and they saw Castillo as a potential closer who could solidify their bullpen down the stretch.
In exchange for Castillo, the Rays received two players from the Mariners: right-handed reliever J.T. Chargois and third baseman prospect Austin Shenton.
Chargois had pitched in 30 games for the Mariners during the 2021 season, recording a 3.00 ERA and 28 strikeouts in 30 innings pitched. Shenton was a promising prospect who had played in the minor leagues, with a reputation for good contact skills and power potential.
The trade was seen as a win-win for both teams. The Mariners got an experienced closer who could help them make a push for a playoff spot, while the Rays received two players who could help strengthen their bullpen and add depth to their farm system.
However, some Rays fans were disappointed to see Castillo go, as he was a popular player who had been a key part of their success over the past few years.
Castillo’s Performance With the Mariners
After the trade, Diego Castillo joined the Seattle Mariners’ bullpen and immediately became one of their top relievers. He appeared in 21 games for the Mariners during the remainder of the 2021 season, recording four saves with a 1.76 ERA and 25 strikeouts in 15 1/3 innings pitched.
Castillo’s success with the Mariners helped them stay in the playoff race until the final weeks of the season.
Compared to his performance with the Rays, Castillo actually improved after the trade. He had a lower ERA with the Mariners and recorded more strikeouts per inning pitched.
He also appeared to be more comfortable pitching in high-pressure situations, as evidenced by his four saves with the Mariners compared to 14 saves with the Rays.
Castillo’s success with the Mariners can be attributed to his ability to fit seamlessly into their bullpen. He was primarily used as a closer, taking over the role from Kendall Graveman after Graveman was traded to the Houston Astros in late July.
Castillo’s fastball-slider combination was effective against both right-handed and left-handed batters, making him a versatile weapon for the Mariners in late-inning situations.
Overall, Castillo’s performance with the Mariners was impressive and showed that he could be a valuable asset for any team in need of bullpen help. While it was tough for Rays fans to see him go, the trade ultimately worked out well for both Castillo and the Mariners.

Meanwhile, J.T. Chargois provided an immediate boost to the Rays’ bullpen, pitching in 18 games with a 1.69 ERA and 17 strikeouts in 16 innings pitched during the remainder of the 2021 season.
