In the first season of interleague play in 1997, a 94-loss edition of the Philadelphia Phillies pulled off a three-game sweep of the New York Yankees, the then-reigning World Series champions.

To their credit, the Yankees — who are now 5 1/2 back in the division — are already getting aggressive ahead of the July 31 trade deadline. New York acquired Colorado Rockies third baseman Ryan McMahon for two pitching prospects on Friday, and the 30-year-old is expected to make his Yankees debut on Saturday afternoon.

Today's Phillies vs. Yankees predictions are bullish on Kyle Schwarber and Philadelphia's lineup against Marcus Stroman.

The Phillies are half a game behind the New York Mets for the top spot in the NL East at 58-44. They blew a chance to finish off a three-game sweep of the Boston Red Sox their last time out on Wednesday, but allowed 6 runs with two outs in the fifth inning, squandering a 5-0 lead before eventually losing 9-8 in 11 innings.

The Philadelphia Phillies and New York Yankees are back at Yankee Stadium on Saturday for Game 2 of their weekend series.

Paul Goldschmidt's off-balance throw was the Yankees' ninth error in four games as another loss dropped them 5½ games back in the AL East.

Ryan McMahon is now a New York Yankee. The former Colorado Rockie recently shared that he had always dreamed of playing for the Yankees.
