The Mets trailed the Phillies by six games for first place in the NL East. Helsley’s latest letdown occurred on Friday, when the right-hander allowed two earned runs, recording only one out in the seventh inning, to flush a Mets lead. Overall, Helsley has allowed nine hits in 5 ¹/₃ innings since his arrival.
