Fantasy Impact: Clase, the No. 10 prospect in the Mariners organization, bounced up-and-down from Triple-A Tacoma and Seattle this season. It's possible the Blue Jays call him up towards the end of the season.

Luis Castillo delivered a stellar performance, tossing six scoreless innings, allowing five hits and two walks while striking out seven in Wednesday's 2-1 loss to the Angels.

Fantasy Impact: Despite his strong outing, Castillo's efforts weren't enough to secure a win for the Mariners, leaving his record unchanged. His season ERA now sits impressively at 3.38, with a WHIP of 1.16, maintaining his status as a reliable fantasy option. Castillo's high strikeout rate of 8.7 K/9 and solid 3.41 strikeout-to-walk ratio continue to make him a valuable asset in fantasy leagues, especially in categories that reward pitching precision and efficiency. His performance in this game, albeit in a losing effort, should keep him high on fantasy radars.

Mitch Haniger went 1-for-3 with a home run and an RBI in the Mariners' 2-1 loss to the Angels.

Fantasy Impact: His solo shot accounted for all his hits in the game, adding a walk to his stat line. Despite the home run, Haniger's season has been underwhelming with a .207 batting average and a .279 wOBA over 86 games. His power numbers are modest, with this game's homer being his ninth of the season. Fantasy managers should view Haniger as a potential depth piece in larger formats, but his current production doesn't warrant widespread rostering in standard leagues. His high strikeout rate and low batting average limit his appeal, though he can provide occasional power surges like today's performance.

Julio Rodriguez (ankle) is expected to be re-evaluated around August 1, per GM Justin Hollander. (Source: Seattle Sports on Twitter )

Fantasy Impact: Rodriguez is eligible to return on August 1, but could require more time if he is not able to ramp up prior to that date. Victor Robles will likely continue to see the bulk of the starts in center field in Rodriguez’s absence.

J.P. Crawford (finger) is expected to miss 4-to-6 weeks, per GM Justin Hollander. (Source: Shannon Drayer on Twitter )

Fantasy Impact: Crawford is dealing with a fractured right pinkie and is currently on the injured list. Although he will not require surgery, he will miss a significant amount of time.

Cade Marlowe is out of the starting lineup for the Mariners Wednesday.

Fantasy Impact: Marlowe will head to the bench after going 1-for-2 Tuesday. Mitch Haniger will start in right field and bat fifth against the Angels.

Logan Gilbert delivered a strong performance, allowing just one earned run on four hits and one walk while striking out eight over 6.2 innings in Tuesday's 5-1 loss to the Angels.

Fantasy Impact: Despite the solid outing, Gilbert's efforts weren't enough to secure a win, as his record dropped to 6-7. His season ERA and WHIP continue to impress at 2.72 and 0.86, respectively, underscoring his reliability as a top-tier fantasy option. With a K/9 of 8.5 and a stellar 5.08 strikeout-to-walk ratio, Gilbert remains a must-start in fantasy lineups, though his win-loss record may not fully reflect his individual performance due to occasional lackluster team support.

Jason Vosler is in the starting lineup for the Mariners Tuesday.

Fantasy Impact: Vosler will serve as the DH and bat seventh against the Angels. He is a career .210 hitter, with 10 home runs, and 31 RBI in 233 at-bats.

Tyler Locklear is in the starting lineup for the Mariners Tuesday.

Fantasy Impact: Locklear will start at first base and bat sixth against the Angels. He is hitting .200, with two home runs, and three RBI in 30 at-bats this season.

Luke Raley is in the starting lineup for the Mariners Tuesday.

Fantasy Impact: Raley will start in left field and bat fifth against the Angels. He is hitting .233, with 11 home runs, and 29 RBI this season.

Mitch Garver is out of the starting lineup for the Mariners Tuesday.

Fantasy Impact: Garver will head to the bench after going hitless Monday. Jason Vosler will serve as the DH and bat seventh against the Angels.

Fantasy Impact: Rivas, Tyler Locklear and Cade Marlowe all have lockers in the clubhouse for Seattle. The moves should all be made official later on Tuesday.

Bryce Miller delivered a stellar performance, tossing seven shutout innings while allowing just three hits and striking out five against the Angels on Monday.

Fantasy Impact: Despite his efforts, the Mariners couldn't capitalize, ultimately losing 3-1. This outing was a bright spot for Miller, who maintained his strong season form, evidenced by a solid 3.41 ERA and a 1.03 WHIP. His ability to keep walks to a minimum, as seen in this game, and sustain a low BABIP (.243) continues to make him a reliable option in fantasy leagues. While wins are elusive, his consistent performance across key metrics like K/9 and FIP suggests he remains a valuable asset for fantasy rosters, especially in categories that reward pitching precision and efficiency.
