Casparius will serve as the Dodgers' opening pitcher Tuesday in Game 4 of the World Series against the Yankees, J.P. Hoornstra of DodgersNation.com reports.
It will be the first appearance during the World Series for Casparius, who had three scoreless outings versus the Mets in the NLCS. The Dodgers have not revealed who else will pitch Tuesday, but Brent Honeywell is a candidate for multiple innings.
