(CNN) Rankings leader Pieter Devos will be hoping to keep German favorite Daniel Deusser at bay when the sixth round of the Longines Global Champions Tour takes place in Hamburg this weekend.

Belgium's Devos leads Deusser by five points after missing the Madrid leg of show jumping's premier circuit, but with two of his top horses Claire Z and Apart in action, Devos will be looking to build on last year's Global Champions League team victory with St Tropez Pirates in Hamburg.

Past winners Ludger Beerbaum and defending champion Harrie Smolders will also be competing as the circuit enters the second quarter of the series and the second of 13 European stops.
