EDGE Analysis

The Cubs threatened, but were unable to break through against Thornburg, who did not allow a run to preserve a 5-4 win. The 27-year-old has not allowed an earned run since July 28, lowering his ERA from 2.38 to 1.61 over that stretch. Thornburg has excelled in the closer's role since his predecessor, Jeremy Jeffress, was traded to Texas on Aug. 1, going seven-for-eight in save opportunities while continuing to rack up strikeouts. He's up to 81 whiffs in 61.2 innings this year, establishing himself as one of baseball's best relievers.
