2. Luis Robert Jr, OF (Chicago White Sox)
While the Mariners did just trade for a star outfielder, why not trade for another? Robert is a center fielder, which normally is occupied by Julio Rodriguez. But right now, Julio is on the ten day injured list with a high ankle sprain. He will be re-evaluated once he reaches those ten days, but there is no certainty that he will be ready once eligible to come off the injured list.
In the meantime, the Mariners have been linked to Luis Robert for some time now. He plays Gold Glove level defense while providing some serious pop at the plate. Robert's biggest struggle is staying on the field. Robert has only played above 98 games in a season just once in his career, so saying he struggles to stay healthy is an understatement.
But when he is healthy, he, like Vladimir Guerrero Jr., is a game wrecker. He has light tower power, which was on full display at T-Mobile Park earlier this year when the White Sox were in town. In the four-game series, he hit three home runs and drove in four. At that time (June 10-13), Robert had more home runs in T-Mobile Park than Julio Rodriguez did.
Unlike the Arozarena trade, the Mariners will have to part with some of their top-ranked prospects to get Robert. We are talking about one or more of Cole Young, Colt Emerson, Lazaro Montes, Harry Ford, or Felnin Celesten. That would be a major "High Risk, High Reward" trade, but one the Mariners should make. An outfield with Arozarena, Julio, and LouBob would be a massive upgrade over what the Mariners trot out there every day.
