Luis Castillo Finally Beats The Tigers On Wednesday

Seattle Mariners right-hander Luis Castillo was finally able to beat the Detroit Tigers for the first time in his career on Wednesday in the team's 3-2 win at T-Mobile Park while also picking up his first win of the 2025 campaign. The 32-year-old veteran allowed two earned runs on five hits (one homer) while walking two and striking out five in seven innings of work. One of the two runs he allowed on the day came on a solo home run to infielder Trey Sweeney. Castillo lost his first outing of the year against the division-rival A's last week, but he gave up just two runs while striking out four in five innings. While he displayed a drop in strikeout rate in 2024 and may no longer be a fantasy ace, his first two outings of 2025 remind us that he's still fantasy relevant in all formats. Castillo is lined up to make his third start of the year next week against the Houston Astros.

Luis Castillo Throws Bullpen On Monday

Seattle Mariners right-hander Luis Castillo (hamstring) was seen throwing a bullpen session at spring training on Monday. Castillo should be full-go in spring training this year despite ending the 2024 season on the injured list due to a Grade 2 left-hamstring strain, which was suffered on Sept. 8. The 32-year-old veteran hurler was mentioned in offseason trade rumors as the Mariners searched for more offense, but he's still around and should open the 2025 season at the top of the starting rotation. In his second full season in Seattle in 2024, the three-time All-Star went 11-12 with a 3.64 ERA (3.91 FIP), 1.17 WHIP and 175:47 K:BB in 175 1/3 innings over his 30 starts. Castillo is still a decent No. 2/3 fantasy starter, but his decline in strikeout rate and decline in his signature changeup are a bit worrying. The days of Castillo being considered a fantasy ace are over.

Baltimore, Seattle Having Trade Discussions Around Luis Castillo

According to Jon Morosi of the MLB Network, the Seattle Mariners and Baltimore Orioles have had trade discussions around starting pitcher Luis Castillo. Morosi noted that both teams have had discussions over the recent days and a potential trade would work since the Orioles would be able to take on a majority of Castillo's contract. In addition, the Mariners have been shopping Castillo throughout the offseason in hopes to move his contract to either acquire a top prospect or open up salary to sign one of the current free agents. Morosi noted that a top prospect would likely go back to Seattle in this deal which could allow them to target one of the top remaining free agents such as Pete Alonso. The Mariners have a lot depth at starting pitcher and could move Castillo to either continue to bolster their deep pipeline or use that money to sign a top bat. Alonso would be a great fit especially as the Mariners do not have a high-upside option at first base. In the deal, Baltimore may have to part ways with one their top prospects such as Heston Kjerstad or Coby Mayo. Both have had struggles finding consistent playing time in a deep Baltimore lineup and would benefit well in a full-time role in Seattle. Castillo would be a much-needed addition for Baltimore as they recently lost Corbin Burnes in free agency to the Arizona Diamondbacks.

Several Teams Inquiring On Luis Castillo

According to Ken Rosenthal of The Athletic, The Chicago Cubs, Boston Red Sox, Baltimore Orioles, and New York Mets are among the teams inquiring about Seattle Mariners starting pitcher Luis Castillo. Rosenthal noted that while the Mariners are not actively searching for a trade partner, they would be eager to do business to improve other aspects of their roster. With their rotation being their strong suit, moving Castillo could bring an impact bat into the Seattle lineup. In addition, Rosenthal noted that if Castillo were to be traded, this could open up some salary for the Mariners to target free agent first baseman Christian Walker, who has been connected to Seattle throughout the offseason. While Castillo's ratios took a slight step down last season, the 32-year-old remains a high-volume starting pitcher who has logged at least 150 innings over the past three seasons and over 175 in the past two.

Luis Castillo Could Return Next Week

Seattle Mariners starting pitcher Luis Castillo (hamstring) could return from the injured list as early as September 23. The team remains optimistic their 31-year-old ace could be activated after a minimum stay on the 15-day injured list. Castillo hit the IL with a hamstring strain on September 10. Manager Dan Wilson did not express much detail about his progression, but seeing that the team remains optimistic is a promising sign. Before the injury, Castillo held a 3.64 ERA, 1.17 WHIP, and a 47:175 BB:K ratio across 175 1/3 innings of work this summer with an 11-12 record. If Castillo returns next week, fantasy managers should expect right-hander Emerson Hancock to drop out of the rotation.

No Definitive Timeline On Luis Castillo

Seattle Mariners interim manager Dan Wilson said he didn't have a definitive timeline on right-hander Luis Castillo (hamstring) and if he'd be able to be activated from the 15-day injured list when he's eligible next Tuesday. "Progressing as he should be ... I think as far as we know right now, he's doing well," Wilson said. Castillo was placed on the IL on Tuesday due to a Grade 2 left-hamstring strain, but it remains to be seen if he'll be able to rejoin the team's starting rotation before the end of the 2024 regular season. He has already received a platelet-rich plasma injection. At best, Castillo might make two more starts for the Mariners the rest of the way as they look to secure a wild-card spot in the American League. The three-time All-Star hasn't been as dominant this year, but he's still been useful in all fantasy formats with a 3.64 ERA and 1.17 WHIP with 175 strikeouts and 47 walks in his 175 1/3 innings over 30 starts.

Luis Castillo Goes To Injured List

Seattle Mariners starting pitcher Luis Castillo (hamstring) has been placed on the 15-day injured list on Tuesday. Ugh, this news comes after Castillo left early during Sunday's game due to a hamstring issue. After undergoing further testing it was determined that Castillo suffered a Grade 2 hamstring strain. At this point in the season it's uncertain if Castillo will take the mound again in 2024. He was pitching well with a 3.64 ERA, 1.16 WHIP, and 175 strikeouts over 175 1/3 innings of work this season. The Mariners haven't announced who is going to take over in the starting rotation. Regardless, most fantasy managers can move on from Castillo with the playoffs starting in most formats.

Luis Castillo Dealing With Hamstring Strain

Seattle Mariners right-hander Luis Castillo (hamstring) was removed from his start early on Sunday against the St. Louis Cardinals due to a left-hamstring strain. Before leaving, Castillo allowed two earned runs on five hits while walking one and striking out three in three innings of work at Busch Stadium. He will undergo an MRI exam on his hamstring on Monday when the team arrives back in Seattle, and at the very least, his next start is in jeopardy. If the 31-year-old's hamstring injury is serious enough, Castillo may not make it back for the rest of the regular season. Losing Castillo for the rest of the way would be a serious blow to Seattle's chances of catching the division-rival Astros for the American League West division lead. Castillo has gone 11-12 this year with a 3.64 ERA, a 1.17 WHIP and 175 strikeouts in 175 1/3 innings of work over his 30 starts for the M's.

Luis Castillo Throws Sixth Consecutive Quality Start

Seattle Mariners starting pitcher Luis Castillo dominated the Mets on Sunday, tossing six innings of one-run ball while striking out nine. Castillo allowed just four hits and two walks in this one. The 31-year-old has been a consistent presence all year, but he's been especially good since the start of July, racking up four wins, a 2.27 ERA, a 1.03 WHIP, and 45 strikeouts in 43 IP. He seems to be finding his groove at the perfect time for both the Mariners and his fantasy owners, who should treat him as a must-start pitcher down the stretch.

Luis Castillo Finishes First Half On A High Note

Seattle Mariners starting pitcher Luis Castillo continued his strong season by picking up his eighth victory of the season in an 11-0 blowout victory against the division rival Los Angeles Angels. Castillo was not needed deep into the contest with such a big lead, but he was productive in his six innings of work. Over that span, he allowed four hits, zero runs, two walks and struck out five on the evening. The veteran entered the season with the expectation of being of the first pitchers selected in 2024 drafts and has backed up his performance this year with a 3.53 ERA and 116 strikeouts over 117 1/3 innings. The only flaw, if there is one with Castillo is that the Mariners offense could hold him back from getting more victories. Outside of that, he can safely be ranked as a top tier pitcher the rest of the way.
