Randy Arozarena - Starting as DH Tuesday Arozarena (hamstring) is batting cleanup as the designated hitter Tuesday against the Athletics.
Impact Arozarena missed the series opener against the Athletics Monday after departing Sunday's game against the Rangers due to a minor hamstring injury. The outfielder is making his return as expected Tuesday, but it comes with not having to take the outfield. With Arozarena batting as the designated hitter Tuesday, Miles Mastrobuoni is starting in left field and batting ninth

Luis F. Castillo - Booted from 40-man roster The Mariners designated Castillo for assignment Tuesday.
Impact The transaction frees up a spot on the 40-man roster for waiver claim Leody Taveras. Castillo has posted a 7.71 ERA, 2.71 WHIP and 5:7 K:BB across seven innings (two starts) this season during his time in the majors.

Leody Taveras - Claimed off waivers by Mariners The Mariners claimed Taveras off waivers from the Rangers on Tuesday.
Impact Seattle will be responsible for the remainder of the $4.75 million Taveras is owed in 2025 and it will retain control of the outfielder through the 2027 season. Taveras has slashed only .241/.259/.342 for Texas this season and has a career OPS of .661, but the switch-hitting 26-year-old is a viable depth option for a team that has Victor Robles (shoulder) and Luke Raley (oblique) on the injured list and Randy Arozarena (hamstring) banged up. Taveras could see ample playing time in right field for the Mariners.

Felnin Celesten - Making plenty of contact Celesten is hitting .333 with two home runs, six steals and a 16.3 percent strikeout rate in 22 games for Single-A Modesto.
Impact Celesten and Sebastian Walcott of the Rangers were the top two shortstops in the 2023 international signing class, but injuries early in Celesten's career led to him falling behind. This year marks his first exposure to full-season pitching, and while his 26 percent hard-hit rate isn't amazing, he should have no trouble growing into plus power, and his 81.7 percent contact rate is a very strong mark for a 19-year-old with his tools.

Samad Taylor - Returns to Triple-A The Mariners optioned Taylor to Triple-A Tacoma on Tuesday.
Impact The 26-year-old had his contract selected from Tacoma last Tuesday, and he went 1-for-8 with a run in four games during his week in the majors. Taylor is returning to Triple-A since Dylan Moore (hip) was reinstated from the 10-day injured list.
