Grilli allowed a tying homer to Devin Mesoraco in the ninth inning of Thursday's 4-3 victory over Cincinnati. He has blown four save opportunities this season after converting 33 of 35 chances a year ago.
Speaking before Friday's game at the Cubs, Hurdle says Mark Melancon will close for now. He also says he could use Tony Watson in save opportunities.
Grilli is 0-2 with 11 saves and a 4.34 ERA in 20 games this year. Hurdle says Grilli is "all about doing what's best for the club and getting better. We'll definitely need him as the season plays out."
Melancon is 1-2 with a 1.89 ERA and 10 saves this season.
