When Brendon McCullum is in full flight, being at the other end of the pitch is a great vantage point.
The Black Caps skipper has been nearly unstoppable during the past year and Kane Williamson got a first-hand look at McCullum's whirlwind 195 during the first innings of the Boxing Day test against Sri Lanka in Christchurch.
During the second session on day one, Williamson could only stand and watch in awe as McCullum took apart the Sri Lankan bowling attack at breakneck speed. Williamson and McCullum put on 126 for the fourth wicket, which helped New Zealand set up their eight-wicket win.
"I think after lunch, I certainly struggled in Christchurch and he was whacking it to all parts and it kind of felt like I was the library in a theme park," Williamson said when asked what it was like to bat with McCullum.
"He was doing everything and I was kind of watching, and it was a great place to watch him bat and I was trying my best at the other end but it's certainly fantastic the way he's going."
