Newport County got the new season off to a flying start with a win at promotion hopefuls Mansfield Town.
Ismail Yakubu headed in Andy Sandell's free-kick to put County in front, then Tony James fired home a half-volley.
Jake Speight and former County player Matt Green drew Town level but a stooping header by Newport forward Aaron O'Connor restored the lead.
Jefferson Louis made it 4-2 from Danny Crow's cross before Speight headed his second and Stags' third goal late on.

Mansfield Town manager Paul Cox told BBC Radio Nottingham:
"They were schoolboy errors. I don't think Newport have had to work hard to score goals against us, which is very untypical of my sides.
"It happened and we have to take it on the chin but I am not happy at all.
"I just think it was a lack of discipline. We conceded goals that were uncharacteristic of us."
