Hayes (hand) is starting at third base and batting leadoff Sunday against the Cubs, Mike Persak of the Pittsburgh Post-Gazette reports.
A trip to the injured list was being considered given Hayes sat out the past five games with a bruised right hand, but he'll rejoin the lineup Sunday while making the first start of his MLB career at the top of the order. The 24-year-old is hitting .223/.291/.319 in 26 games since the start of August and will attempt to get back on track following the absence.
