Parnell to close for Mets
Parnell has struggled in the closer's role in the past, converting only six of 12 save opportunities last season. He has seven career saves in 22 chances.
Collins said Parnell's "confidence is much better," earning him the nod. Parnell is 1-1 with 15 holds and a 3.19 ERA in 36 appearances this season. He has 31 strikeouts in 31 innings pitched.
