Old school, new school: The Tampa Bay Rays have two pitchers who have started 20 games this year. One is their ace, Blake Snell, whose 2.03 earned-run average ranks second in the American League. The other is Ryne Stanek, a reliever turned “opener” — in his case, a right-hander who works the first inning or so, followed by a left-hander. In a year in which the Rays lost starters Anthony Banda, Jose DeLeon and Brent Honeywell to Tommy John surgery and traded starters Chris Archer and Nathan Eovaldi, the team leads the AL in ERA since May 19, when Sergio Romo debuted as Tampa Bay’s first “opener.” There is no pitching statistic more derided in sabermetrics than wins for a pitcher.
