For the first time since November of 2006, the cross-town rivals that reside in Chicago have agreed upon a blockbuster deal, with southpaw Jose Quintana going to the friendly confines of Wrigley Field after a late-morning trade Thursday.

Going to the Chicago White Sox‘s talent-laden farm system include top prospects Eloy Jimenez and Dylan Cease, who were the top 2 prospects in the Chicago Cubs‘ system, per Matt Rose and Bryant Flete are not considered top 30 prospects. According to Jon Morosi of and Bob Nightengale of USA Today, the Houston Astros, the New York Yankees, the Milwaukee Brewers, and the Atlanta Braves expressed interest in acquiring Quintana.

Quintana, 28, has been one of the better pitchers over the past few years, as his fWAR is 7th since the start of 2013. Highly underrated, Quintana has pitched to a 3.48 ERA and a 44-48 record since 2013, logging 200 innings or more in every season.

However in 2017, Quintana has faced numerous struggles, as his 4.49 ERA is the highest of his career. Despite this, Quintana has shown promise over since the beginning of June, as he has posted a 2.70 ERA in 40 innings of work over 7 starts, with 45 strikeouts and 16 walks. On the 2017 season, Quintana has seen an increase in strikeouts and walks, as his K/9 is at 9.4, a career high, and BB/9 is at 3.5, which is also a career high.

Quintana is seen as a great fit for the Cubs, as the Cubs’ rotation lacks depth and is in dire need of a jump-start. Furthermore, John Lackey and Jake Arrieta are set to be free agents following the season. Quintana is cost-efficient as well, as he is under team control until at least 2020 and will make only $7 million this year and $8.5 million in 2018. The 2019 and 2020 club options are both worth $10.5 million, but the 2020 option price rises if Quintana finishes top 3 in the Cy Young voting.

As for the White Sox, they will now have 7 of baseball’s top 100 prospects, according to Baseball America’s newly released Top 100 leaderboard. They consist of the following prospects:

The only team to have more prospects within the Top 100 are the Atlanta Braves, who have 9 prospects within the Top 76.
