So now the Cubs know that the rotation for the rest of the season is, in whatever order you want: Jon Lester, Jake Arrieta, Jose Quintana, Kyle Hendricks and John Lackey.
The Cubs trail Milwaukee by 5 1/2 games in the division at 43-45 after ending a 108-year championship drought last fall.
It's only the 15th deal in history involving clubs more than a century old and the first since 2006.
Some questioned whether the rumors were getting to Quintana, as he posted a 5.60 ERA over his first 11 starts of the season.
"This may not be good for us in the short term", he said. In 1973, the Cubs traded nine-time All-Star Ron Santo to the White Sox for a total of four players, including future Cy Young victor and current White Sox broadcaster Steve Stone.
It may turn out to be the boldest move any team makes before the July 31 non-waivers trade deadline, executed by the gutsiest executive in the game to pull it off. In 42 games with Myrtle Beach, he hit.271 with eight homers and 32 RBIs, with 23 runs scored. Lackey's a free agent after the season, and if he's not part of the playoff equation - he's probably behind fifth-starter options Eddie Butler and Mike Montgomery, too - maybe the Cubs try to trade him and get something for beyond 2017. Quintana was an All-Star and a AL Cy Young Award contender last season, and boasts a career 3.51 ERA over six seasons. He was the Cubs' No. 1 overall prospect according to MLB Pipeline.
The deal, which was consummated quickly, took the baseball world by surprise and caught fans off-guard as they prepare for the second half of the season.
The Cubs won't get to show off new pitcher Jose Quintana just yet, but they are back in action against Baltimore and looking to get on track following a disappointing open to the season.
The White Sox (38-49) haven't made the playoffs since 2008. The Cubs gave up their top two prospects in Jimenez and Cease. While Jimenez may have been the last great hitting prospect in the minors and Cease may have been the pitcher with the highest ceiling, plenty of quality low-ceiling players still remain. Over the off-season they acquired numerous top prospects in trades with the most notable being Yoan Moncada and Michael Kopech from Boston in the Chris Sale trade, as well as Lucas Giolito and Reynaldo Lopez from the Nationals in the Adam Eaton deal. Epstein and White Sox GM Rick Hahn were able to iron out a deal the worked for both sides without too many other partners driving up the price.
