Mariners rumors: Why Luis Castillo is most likely starter trade despite return to form appeared first on ClutchPoints . Add ClutchPoints as a Preferred Source by clicking here .
It has been an up-and-down season for Mariners starter Luis Castillo , as he has not displayed the dominance he once had. But there has been improvement in recent outings. Despite his improvement, he may still be traded away , according to Ken Rosenthal of The Athletic.
"Nearly two months ago, The Athletic wrote about the potential for the Seattle Mariners to trade a starting pitcher at the deadline. That potential appears even stronger now that Luis Castillo has returned to form," Rosenthal wrote.
The Mariners have six starters, and it's worked perfectly for them. Significantly, it is a major reason they currently are in first place in the AL West. While the Mariners starters have thrived, it has not always been fluid or consistent. Castillo is 3-7 with a 4.79 ERA in 17 overall games. Yet, he has also had a 3.25 ERA in 44 1/3 innings since May 14. That was around the time they started their unique plan.

Although Castillo has had some great moments this season, he also has the highest contract on the team, at $22.75 million. The M's are in great shape on the mound, ranking fifth in team ERA across starting pitchers and relievers. Much of that has to do with the piggyback option, as their six starters have often rotated in and out of the bullpen.
The Mariners likely need a strong reliever and a right-handed hitter, which will increase the pressure to find a trade partner willing to take on Castillo. His return to form has given them a better chance of finding that trade partner.
