Barrero (hand) will begin the season on the 10-day injured list, Charlie Goldsmith of The Cincinnati Enquirer reports.
Barrero underwent surgery on the hamate bone in his left hand in late March and was given a six-week timetable. That means he'll get to avoid the 60-day injured list, but it will still be awhile before he's ready to go. Kyle Farmer should be the everyday shortstop until he returns.
