The Seattle Mariners, all season long, kept pitching Luis Castillo and lost so many games because of it. Then President Jerry Dipoto traded the disgruntled Castillo to the Chicago White Sox for Seranthony Dominguez and prospect Boston Smith.
The White Sox took on all of Castillo's contract and sent more money on top of it to the Mariners.
At first, this trade looked like a huge loss. Dominguez for the Mariners allowed 4 runs in 1/3 of an inning, while Castillo, against a horrible Cincinnati Reds offense, pitched a seven-inning shutout with 10 strikeouts.
Castillo has reverted back to who he is, allowing 5 runs in 4 innings, 3 runs in 4.2 innings, and recently gave up 4 runs in 2.2 innings, allowing 8 hits.
For the White Sox, he's 1-1 with a 5.89 ERA, 1.53 WHIP, and 2.5 home runs per 9 innings. The White Sox are 1-3 in his starts.
Meanwhile for the Mariners, Dominguez, after that disastrous first outing, has pitched well.
Since that one awful outing, which messed up his numbers, Dominguez has allowed three runs in seven innings in his last nine appearances. Dominguez has played a critical role in the last four Mariners victories.
The crown jewel of the trade is catching prospect Boston Smith.
Smith for the Arkansas Travelers is hitting .302/.422/.774 for a 1.196 OPS with seven home runs in only 53 at-bats.
Keep in mind the Texas League is a pitchers league, and most of the Mariners best prospects have struggled to hit there.
It's as if Dipoto pulled off another incredible deadline move once again.
Dipoto somehow managed to get a top prospect, the White Sox, to take on the entire contract and still found a way to take back a player who can contribute to this team.
These kinds of trades and farm building are why I've been hesitant to call for Dipoto's firing.
Keep in mind that Dipoto did not hire Dan Wilson; John Stanton did.
Dipoto has done his best to give his incompetent manager all the help he needs.
Hopefully, getting rid of Castillo, as I predicted, was a huge addition-by-subtraction trade to win the division.
