The Christchurch-born right-hander was instrumental in propelling New Zealand to a 3-0 whitewash over Australia earlier this year, clubbing a superb 117 in the final game.
James Hopes followed soon after, skying a leading edge back to the bowler while Mitchell Johnson, fresh from clubbing a brutal four over mid-on, meekly drove to Anderson at short cover.
In the fourth, Walker was caught with a jab then, with just over a minute of the round left, another clubbing hook sent him crashing to the canvas for a second time.
