What happened: The Pittsburgh Pirates acquired left-handed reliever Brandon Eisert and infielder the same Jacob Gonzalez who hit his first career home run for the White Sox last month from the Chicago White Sox on Friday night. Pittsburgh sent minor league left-hander Jaden Woods and the No. 34 overall pick in Saturday's draft back to Chicago as part of the deal.

Why it matters: The trade gives Pittsburgh immediate bullpen depth and a Triple-A bat with major league experience without adding to the 40-man roster long-term. Eisert has already worked in the majors this season, while Gonzalez made his MLB debut with Chicago before the swap.

By the numbers: Eisert is 2-1 with a 5.93 ERA in 25 games, including four starts, this season. Gonzalez was hitting .320 with 19 home runs in 53 games at Triple-A Charlotte. Woods, the return piece headed to Chicago, has a 9.31 ERA in 10 relief appearances at Triple-A Indianapolis.

What to watch: Gonzalez and Eisert are set to join Pittsburgh's active roster as the trade deadline approaches.
