Luis Castillo DVOA, Advanced Stats, & Fantasy Rankings

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.

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.

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.
