Seattle Mariners outfielder Luke Raley (back) is sitting out of Tuesday's series opener against the visiting Baltimore Orioles due to back tightness, according to Adam Jude of The Seattle Times. Dominic Canzone is starting in right field for the M's and will hit cleanup against Orioles right-hander Brandon Young. For now, we'll consider Raley to be day-to-day. If he's feeling better on Wednesday, he could be right back in the lineup against Baltimore right-hander Kyle Bradish. In his sixth year in the majors and third year with Seattle, Raley is on pace to set a new career high in home runs. Through 66 games in 2026 across 210 plate appearances, the left-handed slugger is slashing .241/.303/.503 with an .806 OPS, 14 home runs, 35 RBI, 24 runs scored, and a stolen base. The power is nice from the left side, but the fact that he rarely faces left-handers limits his overall fantasy upside in mixed leagues. Raley has gone just 2-for-16 (.125) with none of his 14 home runs against lefties this season.

The Seattle Mariners announced on Tuesday that they reinstated infielder J.P. Crawford (hand) from the 10-day injured list due to a right-hand contusion, and he's starting at third base and batting leadoff in his first game back in Tuesday's series opener against the Baltimore Orioles and right-hander Brandon Young. The 31-year-old veteran spent the minimum time on the IL with a minor right-hand contusion that he suffered after getting hit by a pitch. Now that he's back, he could spend most of his time in Seattle at the hot corner with infield prospect Cole Emerson settling in at the 6. Crawford returns to an ugly .228/.356/.409 slash line with a .766 OPS, 10 home runs, 23 RBI, 31 runs scored, and a stolen base in his 193 at-bats in 2026. He has now reached double-digit home runs in three of the last four seasons, and he's only striking out 18.9% of the time. Still, Crawford is only rostered in 11% of Yahoo leagues with minimal power for a player with shortstop eligibility. He was heating up at the plate before landing on the IL, hitting .333 with four home runs in his last 11 contests.

Seattle Mariners first baseman Josh Naylor (shin, wrist) is a little banged up and will start on the bench for Tuesday's series opener against the visiting Baltimore Orioles, per MLB.com. Naylor was forced from Sunday's series finale early against the Washington Nationals after fouling a ball off his shin. The 28-year-old left-handed slugger is also dealing with wrist soreness. The good news is that X-rays on his shin came back negative, so Naylor is considered day-to-day and could be back as early as Wednesday's tilt against the O's. Miles Mastrobuoni will start at first on Tuesday for Seattle and will bat ninth versus Orioles right-hander Brandon Young. The Canadian native enters Tuesday's action hitting .253/.315/.372 with a .687 OPS, eight home runs, 32 RBI, 13 stolen bases, and 27 runs scored in 68 games across 296 plate appearances in his first full year with the team. Naylor has gone 12-for-48 (.250) with three of his eight home runs on the year in 12 games in June. Check back on Wednesday to see if he's back in the starting lineup.

Seattle Mariners outfielder Randy Arozarena (hamstring) is missing another game on Tuesday against the visiting Baltimore Orioles at T-Mobile Park, according to MLB.com. Victor Robles is making the start in left field and will bat seventh against Orioles right-hander Brandon Young. The 31-year-old Arozarena is missing a third straight start for the M's after suffering from soreness in his left hamstring last Friday. The good news is that the Mariners expect him to be available off the bench for Tuesday's series opener, giving him a good chance to return to the starting nine for Wednesday's contest in Seattle. When the right-handed-hitting Cuban outfielder returns to action, fantasy managers will want to return him to their starting lineups everywhere. He's been one of the team's most consistent offensive producers in 2026 with a .291/.377/.448 slash line, an .826 OPS, seven home runs, 33 RBI, 19 stolen bases, and 47 runs scored in his 261 at-bats in his second full season with the M's. Arozarena was a second-time All-Star in 2025 in his first year in Seattle, when he hit just .238 (146-for-613), but with a career-high 27 long balls, 76 RBI, and 31 steals in 160 regular-season contests.
