A: When you're Howard Johnson and you had a 30/30 season the year before.
In 1987 HoJo burst into the Mets starting line-up hitting 36 home runs, 99RBIs, and 32 stolen bases. The Mets just missed the playoffs thanks to crappy sinkerball from Roger McDowell to Terry Pendelton! Well, at least that's who I blame it on.
In 1988, HoJo followed his '87 season with a 20/20 campaign hitting 24 home runs, 68 RBIs, and 23 stolen bases.
