The New York Yankees could make a surprising decision come playoff time.

The New York Yankees made a plethora of additions at the MLB trade deadline, the most notable of which was probably third baseman Ryan McMahon.

McMahon is a wizard at the hot corner, having been one of the best defensive third basemen in baseball for years running now. However, his bat definitely leaves something to be desired, as the Yankees have experienced first hand.

Since joining New York in late July, McMahon is slashing .213/.307/.333 with three home runs and 17 RBI over 163 plate appearances. He had a nice little surge upon initially arriving, but his bat has cooled off considerably ever since.

This raises a pretty interesting question with the playoffs looming: could the Yankees potentially bench McMahon in certain scenarios? More specifically, could they sit McMahon against lefties, where he is hitting just .186 this season?

New York also acquired infielder Amed Rosario back at the deadline, who I admittedly referred to as a rather pointless addition along with outfielder Austin Slater earlier in the week. But perhaps there actually is a use for Rosario, who has barely played since his acqusition?

Rosario is slashing .321/.348/.523 versus left-handed pitching this year, and with the Yanks potentially facing Framber Valdez or Garrett Crochet in the Wild Card Round, the idea of inserting Rosario into the lineup may be worth exploring. That's especially considering the 29-year-old owns a lifetime .805 OPS against lefties.

Of course, the problem is that the defensive dropoff between McMahon and Rosario is more than significant. McMahon is a Gold Glove-caliber third baseman. Rosario, meanwhile, is a pretty terrible defensive player. Would the Yankees be willing to risk the dip in defense for an uptick in offensive production?

Based on what New York experienced in the World Series last fall, you would think Aaron Boone would shut that idea down immediately. But maybe the Yankees would weigh the possibility in very specific scenarios?

There is certainly no guarantee the Bronx Bombers will do this, but it is at least something to monitor and keep in mind as we get closer to the postseason.
