The front office crew of the Dodgers said they were going to make a move for a bullpen arm at the waiver trade deadline, and they made good on that promise today.
Istler was a 23rd round draft pick in 2015. He worked his way up from High-A ball to Triple-A this season, ending with 5-2/3 scoreless innings in Oklahoma City.
Madson, a right-handed relief pitcher, has not had a very good season thus far. He just returned from the disabled list, healing from lumbar nerve root irritation in his back. Over the course of the year, he has posted a 5.28 ERA in 49 games and 44-1/3 innings pitched, allowing six homers and 15 walks.
The 38-year-old joined the major leagues in 2003 with the Philadelphia Phillies, who drafted him in 1998. He spent nine years there, winning a World Series with them in 2008. After missing three seasons with Tommy John surgery, he spent time in both Kansas City, were he won a second World Series, and Oakland, before being traded to the Nationals in 2017. He had a 1.83 ERA in 59 innings only allowing two homers and nine walks between the two teams last season.
Madson is on the last year of his three year, $22M contract. He is owed $1.17M, which will be picked up by the Dodgers. To make room for Madson on the roster, the Dodgers designated Adam Liberatore for assignment.
Madson will wear uniform No. 50 for the Dodgers.
