Sheets is out of the lineup for Sunday's game against the Red Sox, Jeff Sanders of The San Diego Union-Tribune reports.
Sheets sat against Boston lefty Connelly Early on Saturday and will do so again Sunday versus southpaw Ranger Suarez. Sheets' only start against a lefty came on Opening Day. The 29-year-old has a .636 OPS through 21 plate appearances this year, though he's been more productive over his past three contests, going 5-for-10 with two doubles, a steal, two RBI and three runs.
