If there was such a clause, you could assume Grilli may get chances to close games, Biertempfel said.
Grilli will also receive a $500,000 signing bonus on top of his 2013 salary of $2.25 million. In 2014, Grilli will make $4 million.
Grilli has been a rock for the Pirates in his two seasons with the team. After being picked up midway through the 2011 season, Grilli compiled a 2.48 ERA with 37 strikeouts in 32 innings of work.
He was also excellent last season. In 58 innings out of the bullpen, Grilli struck out 90 and walked 22. He had a 2.91 ERA and a 1.14 WHIP.
