Luis Castillo to Start Game 2

Seattle Mariners starting pitcher Luis Castillo will draw the start for Sunday's Game 2 of the ALDS against the Detroit Tigers. The Mariners are in need of a big win here after dropping the opener. It won't be easy versus left-hander Tarik Skubal, but Castillo has looked solid lately. Castillo posted a 2.45 ERA in the month of September. The right-hander gave up three earned runs over his last four starts during the regular season. This is looking like a potential pitcher's duel between two aces on Sunday.

Luis Castillo Keeps the Pirates Scoreless in Seattle

Seattle Mariners starting pitcher Luis Castillo spun seven shutout innings against the Pirates on Saturday night, allowing only two hits and no walks while picking up eight strikeouts. He didn't get much run support but made it stand up in the 1-0 victory. Castillo earned the win to improve to 5-5 on the season with a 3.31 ERA, 3.90 FIP, and 1.22 WHIP. He has allowed three runs or fewer in four of his last five starts, with 27 strikeouts in 30 innings and four quality starts. He doesn't have the elite strikeout numbers from his prime, but he still can deliver strong outings in favorable matchups like this one, especially when he's working at pitcher-friendly T-Mobile Park. He'll get one more start before the All-Star break in a much tougher matchup on Friday night in Detroit.

Luis Castillo Throws Six Shutout Frames On Saturday

Seattle Mariners starting pitcher Luis Castillo (3-2) dominated the Miami Marlins on Saturday, tossing six scoreless innings in a 14-0 win. Castillo allowed just one hit and two walks while punching out five. The 32-year-old was coming off two outings where he allowed 23 baserunners in just 9 IP, so a start like this one was sorely needed. He improves to (3-2) with a 3.62 ERA, 1.39 WHIP, and 28 strikeouts in 32 IP. Fantasy managers will hope he can build off this start next Saturday when he is projected to face the Texas Rangers on the road.

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.
