Worcester broke open a tie game with a four-run fourth inning, as the Red Sox pulled away from the Scranton/Wilkes-Barre RailRiders, 8-3, on Friday at Polar Park.

Oswaldo Cabrera hit an RBI double to give the RailRiders (19-17) a 1-0 lead in the top of the first.

Tsung-Che Cheng responded with a solo homer in the second to tie the game at 1.

In the bottom of the fourth, Matt Thaiss hit an RBI double, and Nick Sogard hit a three-run homer to right-center to give Worcester (21-15) a 5-1 lead.

Anthony Volpe hit an RBI double, and Cabrera added an RBI groundout in the fifth, but Jason Delay’s fifth-inning RBI single and Kristian Campbell’s two-run double in the sixth pushed the Red Sox’s lead to 8-3.

Worcester won three of the four games with two left to play in the series.

The series was scheduled to continue Saturday at 4:05 p.m. with Brendan Beck (2-2 record, 5.11 ERA) slated to pitch for the RailRiders and Michael Sansone (1-2, 5.17) getting the ball for Worcester.
