BOSTON -- Infielder Marco Hernandez will be called up from Triple-A Pawtucket to help the flu-ridden Red Sox, baseball sources have told CSNNE.com.

RED SOX 3, PIRATES 0

• Sandy Leon's walkoff homer in 12th lifts Red Sox over Pirates
• Drellich: With Mitch Moreland on his side this time, Chris Sale's dominating performance doesn't go to waste
• Sale learns from Tom Brady and takes his debut jersey home

Hernandez will not be the corresponding move for Matt Barnes' placement on the bereavement list for a three-day absence, as Noe Ramirez has been recalled. It will be a roster move with players like Brock Holt and Mookie Betts sick with flu-like symptoms. 

The Red Sox played with a short bench in a 12-inning, 3-0 win over the Pirates on Thursday. They've been carrying an extra reliever to start the season with their expected fifth starter, Drew Pomeranz, on the disabled list, so they theoretically could add another position player in place of Barnes.

The fact that the team may well be rained out on Thursday could help the bullpen recover in time for the start of a series in Detroit on Friday.
