Rusney Castillo was 1-for-6 with three strikeouts for Pawtucket on Friday night, but his lone hit was a big one, driving in the game-tying run with two outs in the top of the ninth inning and paving the way for the PawSox's eventual 13-inning win over the Durham Bulls in Game 4 of the Governors' Cup finals.

Pawtucket extended its season with the 4-2 victory, evening the series at two games apiece and setting up a winner-take-all Game 5 for the Triple-A International League championship on Saturday.

Boston Red Sox manager John Farrell said earlier Friday that if Pawtucket were to be eliminated in Game 4, Boston might call up Castillo and others this weekend in Kansas City, Missouri, but after the Red Sox's 4-2 win over the Royals on Friday night, Farrell took that option off the table. He indicated the Red Sox would wait until traveling to Pittsburgh, where a three-game series with the Pirates begins Tuesday, before bringing up Castillo.

Once he does arrive, Castillo will likely go right into the outfield, probably center field.

"He'll be on the field. We aren't going to bring him up just to watch," Farrell said. "So what day he gets on the field remains to be seen."
