CHICAGO (AP) The Chicago White Sox have placed catcher Alex Avila on the 15-day disabled list with a strained right hamstring.
They also purchased catcher Omar Narvaez's contract from Triple-A Charlotte on Wednesday and transferred reliever Jake Petricka to the 60-day disabled list to make room for Narvaez on the 40-man roster.
Avila left Tuesday's game against the New York Yankees with the injury. He is batting .236 with three home runs and six RBIs in his first season with the White Sox.
Narvaez is batting a combined .239 with Charlotte and Double-A Birmingham and has thrown out 12 of 48 attempted base stealers this season.
Petricka had season-ending surgery on his right hip last month.
