This week’s series against the Twins felt like a turning point in the Mariners season, and not in a good way, with Kelenic’s injury, two demoralizing losses, and Jerry Dipoto telling it like it is. And yet, the final game of the set was a satisfying win behind George Kirby’s stellar pitching, and we are back to exactly .500. It’s debut season, with Devin Sweet and Cade Marlowe making theirs against Minnesota, and Prelander Berroa poised for his this weekend. As playoff aspirations become frail, attention shifts to the promise represented by these young players.
