White Sox without pitching coach in Texas

Chicago White Sox pitching coach Don Cooper will miss the three-game series in Texas.

Before the series opener against the Rangers on Tuesday night, the White Sox said Cooper is attending to a personal matter at home in Nashville, Tenn.

Cooper is expected to rejoin the team Friday night in New York for the start of a weekend series against the Yankees.

Bullpen coach Juan Nieves will serve as pitching coach in Cooper's absence.
