David Ross -- a.k.a Grandpa Rossy -- became the oldest Cub to homer in the postseason

As you might have heard, Cubs catcher David Ross is pretty old. He's 39, to be precise, and when he announced that 2016 would be his final season back in February, his teammates decided to have some fun with the team's official dad. Instagram accounts were created. Motorized carts were purchased. Ross even used a rotary phone:

The joke's on them, though, because while he might be pushing 40, all Ross has done this year is rake. He hit 10 homers in the regular season, his most since 2007 -- including a magical long ball during his final home game -- and posted a solid .784 OPS.
And now that he's reached October, he's taken his age from punchline to the record books. With the Cubs trailing, 1-0, in the top of the third inning of NLDS Game 4 against the Giants, Ross took San Francisco starter Matt Moore yard for a solo homer and made some history in the process: He not only became the oldest Cub to hit a postseason homer (breaking 37-year-old Moises Alou's record) but he's also the oldest catcher in baseball history to do so.
Oh, and he followed that up by catching Denard Span stealing with a picture-perfect throw in the bottom half of the frame.

That homer turned out to be pretty big -- thanks to a four-run ninth, the Cubs snuck by the Giants with a 6-5 win to advance to the NLCS. Chicago will meet the winner of Game 5 between the Dodgers and Nationals on Thursday, and Game 1 gets underway Saturday on FOX/FS1.
