With smarter, more analytical front offices, baseball is changing before our eyes. Even in the sport's evolution, however, history can teach us a lot. 

When it comes to this year's MLB trade deadline, teams should be taking a page out of baseball's history book and pounce at the chance to acquire Giants ace Madison Bumgarner, writes The Athletic's Ken Rosenthal.

Sure, Bumgarner is one of the most accomplished postseason pitchers of all time. But in this case, Rosenthal is going back even further than his heroics in 2014, and it all starts with a different left-handed pitcher. 

On July 7, 2008, the Brewers acquired CC Sabathia from the Indians for Rob Bryson, Zach Jackson, Matt LaPorta and a player to be named later. The PTBNL turned out to be three-time All-Star Michael Brantley. More importantly, Sabathia went on one of the greatest stretches by a pitcher we've seen, propelling the Brewers into the playoffs for the first time in 26 years.

Sabathia was unhittable once he joined Milwaukee, going 11-2 with a 1.65 ERA over 17 starts -- seven of which were complete games. What made the trade different than others, however, was its timing. By adding Sabathia in early July, the Brewers had the big lefty for five extra starts compared to him joining the team after the July 31 trade deadline.
