The Seattle Mariners have been one of the more back-and-forth teams during the first half of the 2022 MLB season. Nevertheless, they're close to being a .500 team with a 41-42 record and only sit 4.5 games back of the Boston Red Sox for the final American League wild card spot.

Even though a playoff appearance is an achievable goal, ESPN's David Schoenfield is expecting the Mariners to stay quiet heading into August's trade deadline. However, does say that Seattle should prioritize trading away one specific player in the coming weeks: right-handed relief pitcher Diego Castillo.

Mariners Trade Rumors

The Mariners have been plagued by injuries to key players all season long. Schoenfield says the plan is to hope that everyone gets healthier as the season goes on, rather than making unnecessary trades at the deadline. That's why it makes sense to move Castillo.

The 28-year-old righty is a solid option for any team looking to shake up its late-game bullpen. Castillo is 6-1 with four saves in 31 relief appearances this season. His 4.66 ERA is the highest of his career, but he's still striking out 9.9 batters per nine innings, issuing 11 walks as well.

While Castillo might not be the flashiest trade piece, his being under team control for two more years should net Mariners a decent prospect or two. Considering that the club wasn't expected to be a contender just yet, general manager Jerry Dipoto would be thrilled with that return.

Mariners World Series Odds

FanDuel Sportsbook's latest 2022 World Series odds further illustrate that it might be in Seattle's best interest to sell before the deadline. The Mariners only have +12000 odds (No. 18) to go on a championship run this fall.
