The 1998 Yankees were firing pretty much all season, but they especially came out firing after the All-Star break. Starting in the first game back on July 9th, the Yankees won five of their first six games, as they outscored opponents 29-11.
However, their best performance in that post-break stretch came in a dominant win in their seventh game of it.
