Biggar dedicates Saints' win to boss Boyd
The victory ended a run of 12 successive defeats for the black, green and gold, who celebrated a home league win at Franklin's Gardens for the first time in 2020.
But the Wales fly-half was keen to deflect the praise in the direction of Boyd.
Biggar said: "Nobody wants to continue to lose games week in, week out but this group - for what it is - it's got a group of really good men, good people at the club, all epitomised by the boss.
"The boss has come in every day and he's been positive, he's kept things black and white, there's been no grey areas, he's kept things in perspective with what's going on in the world at the minute.
"This is for him, really. He deserves a huge amount of credit for the way he's kept a real energy about the place.
"This is a big one for him, really."
Saints will now move into 2021, with their first game of the New Year coming at London Irish next Sunday.
Reflecting on the win against Worcester, Biggar said: "I think we played some really good rugby in that first half and probably should have been a fair bit more ahead if we're honest.
"It's been such a challenging year. Before lockdown, we were sort of dusting teams up and second in the league, qualifying for the quarter-finals of the Champions Cup and everything was sort of rosy.
"Then for whatever reason - we still can't quite put our finger on it - we haven't been able to come back the same team. Winning is a habit but losing becomes a bit of a habit as well.
"I'm just pleased for this young group, really, who deserve this victory, especially the forwards. They fronted up exceptionally well and it's really nice to finish 2020 on a little bit of a high."
