After bringing up his fourth ton of the Plunket Shield season while surpassing his previous highest score on day one, Kitchen started this morning on 141 and continued to flay Northern Districts' attack all around University Oval.
The No 6 raced to 200 from just 233 balls before falling shortly after registering the milestone, captured by Ish Sodhi on 207 as Otago declared on 432-8.
In reply, the visitors enjoyed none of Kitchen's success, ending the day on 162-5 and 270 runs in arrears, with Dean Brownlie's 87 the only real bright spot.
All of which would have left Canterbury feeling rather comfortable in Christchurch. The leaders are facing a battle of their own to earn victory over Wellington but, needing only to match their pursuers' results, they would have been content with a position of parity at the halfway point.
After some lower-order resistance from Todd Astle (70) and Logan van Beek (66) helped Canterbury avoid embarrassment and eventually reach 197, the hosts reduced Wellington to 117-5 at stumps to leave the match in the balance, if not entirely relevant.
