Former Chicago White Sox outfielder Aaron Rowand will be a guest radio analyst for the team on Saturday and Sunday, the organization announced on Thursday.

Rowand will fill in for Darrin Jackson, who will be unavailable for the two games due to a family matter. The White Sox face the New York Yankees on the road for a four-game series beginning on Thursday.

Rowand played for the White Sox for five seasons, including the team’s 2005 World Series championship season and scored eight runs and had six doubles during that postseason run. In 11 major-league seasons, he hit .273 with 136 home runs and 536 RBIs.
