• The Mariners went into Saturday's game with a 3.02 ERA, which is a 1.29 improvement from last year's 4.31. That improvement is the best in the Majors this year and would be the fifth-best of any MLB club since 1980 if it holds for the rest of the year. The 1997 Tigers had the biggest drop in ERA in that span, a 1.82 improvement from 6.38 to 4.56.
