James Webster admitted he was a relieved man after beginning his Wakefield tenure with a hard-fought 18-10 victory over relegation-doomed London Broncos.
The Wildcats struggled badly during the first half in particular at a rain-soaked Belle Vue and trailed 10-4 at the break.
Captain Danny Kirmond put the hosts in front early on but the Broncos hit back with tries from Iliess Macani and Thomas Minns to establish a deserved interval lead.
However, the Wildcats improved after the break and tries from Daniel Smith and Matt Ryan in the final quarter of the match put them home and dry.
Rookie Australian coach Webster, who replaced Richard Agar at the helm last week, said: “I’m just relieved to get the win to be honest.
“We played some efficient rugby and the most pleasing thing was we only gave away two tries.
“I thought our defence, other than one line break, was really good.
“It was about respecting the conditions - I thought London did a good job on playing them in the first half.
“I knew they would be tough and the conditions suited them.
“There are a couple of times every couple of years you get conditions like that and we just didn’t acclimatise to them in the first half.
“We dropped the ball seven times when not under pressure but once we decided to respect the conditions we got better.”
Hull FC coach Lee Radford was impressed with his team’s performance as they crushed hosts Widnes.
After the 56-6 First Utility Super League success, Radford said: “Credit to the players. We had a small lead at half time and then we go and do that.
“It was a great performance. We started the second half really well and they have responded excellently to what I’ve asked them.
“It’s a tough place to come here and win. They are in form and have some great players but we got the job done well.
“It’s massive for our confidence and we have come away with a clean bill of health. I’ve seen the confidence coming on and it showed again tonight.”
Hull FC youngsters Callum Lancaster and Jamie Shaul helped themselves to hat-tricks as the Black and Whites embarrassed Widnes in the First Utility Super League, winning 56-6.
