Why Aroldis Chapman is the perfect fit for the Chicago Cubs

1:02 PM ET

The Chicago Cubs have added a much-needed power lefty arm to their bullpen in Aroldis Chapman.

Chicago will reportedly send four players to the New York Yankees in exchange for Chapman.

It’s the third trade between the Yankees and Cubs since July of 2013. Chicago sent Alfonso Soriano to the Yankees for minor leaguer Corey Black in July that year. They also traded Starlin Castro for Adam Warren and Brendan Ryan in December of 2015.

The Cubs’ bullpen looked good in April but has seen its production drop every month since then. Chicago relievers posted a 2.72 ERA with one blown save in April, a 3.80 ERA with two blown saves in May and a 3.96 ERA with four blown saves in June. In July, Chicago’s bullpen has a 4.64 ERA (24th in MLB) and three blown saves (tied for fourth most).

Chicago ranks 14th in the majors in bullpen ERA on the season at 3.83.

Cubs left-handed relief pitchers have allowed a .956 OPS in July. That’s the sixth-highest OPS allowed by left-handed relief pitchers this month.

Chapman’s opponents have a .351 OPS in July, fourth lowest in MLB.
