The Mariners spent most of the summer trying to squeeze six starting pitchers into five spots. They tried a piggyback system and a temporary six-man rotation. They paired Luis Castillo and Bryce Miller, then separated and returned to six starters. Every solution arrived with a fresh explanation and an expiration date.Then came the move that was supposed to end the conversation. The Mariners traded Castillo to the Chicago White Sox on Aug. 2 and returned to a standard five-man rotation.Twenty days later, Kade Anderson is making his major league debut, and six starters are back in the picture. Does this mean we can stop pretending that the number was ever really the problem?The Mariners didn’t have too many starting pitchers. They had six starters, but they weren’t the six starters the organization ultimately wanted to use. That’s the most honest explanation. It also would have saved everyone a lot of unnecessary choreography.Kade Anderson’s Arrival Exposes the Mariners’ Real Rotation PlanAnderson earned this promotion. There is absolutely no debate about it. The 22-year-old left-hander went 10-1 with a 1.06 ERA in 18 starts for Double-A Arkansas. He struck out 135 batters, walked 13 and allowed only 47 hits across 93 1/3 innings.When a pitcher dominates that thoroughly, the roster eventually has to move for him. To be fair, Bryan Woo’s shoulder soreness helped create the immediate opening. Woo had originally been scheduled to start Saturday before leaving his previous outing after 75 pitches. Giving him additional recovery time makes sense. Though his shoulder explains the timing, it doesn’t exactly explain the last three months.The Mariners were already manipulating the schedule to provide extra rest. In late July, Dan Wilson moved Woo up a day and pushed Miller back. Miller had already dealt with an oblique injury and had benefited from additional rest at other points.This was never a group of five pitchers rigidly marching to the mound every fifth day. The staff was already providing breathing room whenever it felt one of its starters needed it. That makes the messaging really weird.When Miller first returned in May, Wilson said the club would use six starters temporarily and then “recalibrate.” The Mariners wanted Woo, Logan Gilbert and George Kirby pitching as frequently as possible, so they moved toward the Castillo-Miller piggyback.That experiment produced good results and awkward scenes. Castillo slammed his glove after being removed from one appearance. Miller said he learned only two days beforehand that he would be the pitcher entering from the bullpen. The Mariners eventually acknowledged the communication breakdown and moved back to a straight six-man rotation.Then the schedule changed, so the explanation changed with it.General manager Justin Hollander said a six-man rotation combined with off-days could place starters on seven-day programs. The solution became a rotating piggyback arrangement involving all six pitchers. Hollander also accepted responsibility for the earlier confusion, saying the communication failure was “100 percent on me.” That plan lasted just about as long as the others.The Luis Castillo Trade Was Right, but the Explanation Wasn’tNone of this means trading Castillo was a mistake. It was the right move. The Mariners found a team willing to assume approximately $30 million in guaranteed money through the end of 2027. They acquired a veteran reliever in Seranthony Domínguez, added catching prospect Boston Smith and moved on from an expensive starter. That’s good business.Castillo also deserved more honesty than the rotation shuffle provided. He was an important part of this era of Mariners baseball, a respected clubhouse presence and the pitcher who helped announce that the rebuild was over in 2022. By 2026, he was 33, overpaid, and standing directly in Kade Anderson’s way. We know leadership has to put out manufactured statements. But this feels like something that could be said plainly. And if not, just don’t be misleading.Six starters were not too many. The Mariners simply did not want to continue using that particular group of six.Add us as a preferred source on GoogleFollow
