Remember the opener? After the Tampa Bay Rays employed it to great effect early in 2018, the opener took Major League Baseball by storm. During the latter half of the 2018 season, the Dodgers, Athletics, Twins, and Rangers made extensive use of the opener to deal with depleted pitching staffs, and both the Athletics and Brewers even used them in the postseason. Although they used it just once in 2018, the Yankees paired Chad Green with Nestor Cortes, Chance Adams, and David Hale 15 times in 2019 to compensate for injuries to the starting rotation.
