White Sox pitcher Michael Kopech reinstated from paternity list; Ryan Burr optioned to Charlotte

NEW YORK — The White Sox optioned right-handed reliever Ryan Burr to Triple-A Charlotte Friday and returned right-hander Michael Kopech from the paternity list.

Manager Tony La Russa said Thursday that he was expecting Kopech to be ready to start Sunday night against the Yankees, who host the Sox for three games this weekend. Friday night’s opening was postponed because of weather and rescheduled as part of a doubleheader on Sunday.

Kopech is 0-1 with a 1.54 ERA and 33 strikeouts in seven starts over 35 innings this season. He went on the Paternity List Tuesday.

Burr (6.00 ERA) allowed six earned runs over nine innings in eight appearances this season. He owns a 4.08 ERA over 66 appearances including two starts during parts of four seasons with the Sox.

Left-hander Dallas Keuchel’s start was moved to Saturday, with Johnny Cueto’s start moved Sunday’s Game 1. Kopech will start Game 2 on Sunday.

The Sox (19-19) lost three of four to the Yankees last week at Guaranteed Rate Field.
