With his batteries recharged after being rested for the T20I series that kickstarted the ongoing New Zealand tour, England's Jos Buttler is happy to be back on the field, scoring runs especially as he found himself under the pump all the time during the "tough summer" back home. 

Buttler was part of England's World Cup winning campaign as well as the unsuccessful Ashes quest, two extremely difficult assignments. 

He built up nicely for the two-match Test series starting November 21 with a century in the three-day warm-up game against New Zealand A in Whangarei.

"It was a tough summer. Great fun but a huge challenge which took a lot out of most of us," Buttler was quoted as saying by ICC.

"So it was good to have some time away from the game and get refreshed."

"I've had four or five weeks off and that has been invaluable. It's allowed us to refresh, have time away and get excited to come back."

His batting in first-class cricket had been a concern; Buttler struggled against the likes of Pat Cummins, Josh Hazlewood in the Ashes, he had scored just five first-class hundreds before this match and only one since 2014. 

"I'm absolutely aware of my record as regards scoring first-class centuries," Buttler said. "It's something I've been very light on, really. I know this was a warm-up match but it's nice to spend time in the middle and get to three figures."

The 29-year-old further said he had been working on his batting with former English opener Marcus Trescothick in the last few weeks. 

"I went down to Somerset to work with Marcus Trescothick, who is someone I know really well. I got a lot out of it."

"It gave some building blocks - more around my set-up, really, trying to be in the right place at the right time when the ball is released - to coming here and feeling in good touch," he added.
