Castillo (0-3) allowed four runs on six hits, two walks and a hit-by-pitch while striking out five over six innings to take the loss Sunday versus the Royals. Castillo was doing fine until the fourth inning, when he allowed four straight batters to reach base to open the inning. Three of them came around to score, and the Royals tacked on an extra run in the sixth. Castillo has allowed at least four runs in five of his seven starts this season, though this is the third time he's allowed four earned runs. He has a 6.29 ERA, 1.66 WHIP and 31:13 K:BB through 34.1 innings. Until Castillo is able to limit baserunners better, he is likely to continue having trouble preventing runs. His next start is projected to be on the road versus the White Sox.

Mariners Injury Report
Mariners Depth Chart
Castillo (0-3) allowed four runs on six hits, two walks and a hit-by-pitch while striking out five over six innings to take the loss Sunday versus the Royals. Castillo was doing fine until the fourth inning, when he allowed four straight batters to reach base to open the inning. Three of them came around to score, and the Royals tacked on an extra run in the sixth. Castillo has allowed at least four runs in five of his seven starts this season, though this is the third time he's allowed four earned runs. He has a 6.29 ERA, 1.66 WHIP and 31:13 K:BB through 34.1 innings. Until Castillo is able to limit baserunners better, he is likely to continue having trouble preventing runs. His next start is projected to be on the road versus the White Sox.
The Mariners designated Thomas for assignment Sunday. Thomas had been part of Seattle's 40-man roster for just over a year but has made just three appearances at the big-league level. He's played exclusively at Triple-A Tacoma thus far in 2026, slashing .260/.313/.328 over 144 plate appearances. Given that he's already 26 years old and producing at a below-league-average level (67 wRC+) at Triple-A, Thomas is a good bet to go unclaimed off waivers.
Seattle claimed Suarez off waivers from Atlanta on Sunday. Suarez has no minor-league options remaining and will be added to the 26-man active roster once he links up with Seattle. The 28-year-old lefty is expected to serve as a multi-inning option out of the Seattle bullpen after logging a 6.61 ERA, 2.08 WHIP and 21:12 K:BB across 16.1 innings frames over eight appearances (one start) with Atlanta this season.
Refsnyder (undisclosed) will start at designated hitter and will bat leadoff in Sunday's game against the Royals. Refsnyder is typically included in the lineup against left-handers, but he took a seat versus southpaw Cole Ragans in the series opener Friday while he contended with a couple minor injuries. The Mariners felt comfortable enough with Refsnyder's health to use him off the bench in Saturday's 3-2 extra-inning win, and after checking out fine afterward, he'll get the green light to start Sunday versus Royals lefty Kris Bubic.
Raley is out of the lineup for Sunday's game against the Royals. With the Mariners facing off against a lefty starter (Kris Bubic) for the second time in the series, the left-handed-hitting Raley will once again exit the starting nine. Connor Joe will replace Raley in right field and will bat seventh.
Canzone is out of the lineup for Sunday's game against the Royals. With the Mariners facing off against a lefty starter (Kris Bubic) for the second time in the series, the left-handed-hitting Canzone will once again exit the starting nine. Rob Refsnyder will replace Canzone as the Mariners' designated hitter.
Raleigh is out of the lineup for Sunday's game against the Royals due to right side soreness and is considered day-to-day, Daniel Kramer of MLB.com reports. Raleigh was sent for an MRI after being scratched from the lineup Saturday due to unspecified soreness, which the Mariners have now identified, but the American League MVP runner-up has indicated that his injured side is already feeling better, per Divish. Raleigh was able to take some swings in the batting cage earlier Sunday, but he's unlikely to get used as a pinch hitter in the series finale versus Kansas City. He could return to the lineup Monday against Atlanta, however, either at catcher or designated hitter.
Munoz blew the save in Saturday's 3-2 extra-inning loss to the Royals, allowing one unearned run on two hits and no walks with one strikeout in the ninth inning. Munoz was called upon to protect a one-run lead in the ninth but gave up a run on a one-out single that was uncharacteristically misplayed by Julio Rodriguez. It continued what has been a somewhat rocky start for the top-tier closer, though the appearance actually lowered his season ERA from 6.00 to 5.54. Overall, he's 6-for-8 in save chances while also posting a 1.38 WHIP and 21:6 K:BB across 13 innings in the early going.
