A stand of 219 in 63.2 overs between Moeen Ali (155*) and Matthew Pardoe (102) saw Worcestershire to 322/3 from 96 overs at the end of the first day of their LV=County Championship match against Glamorgan at New Road.
Hogan took the only wicket of the sessions as in the ninth over, he trapped Daryl Mitchell leg before with the home side on 11.
Next over and with the score on 231, Pardoe edged Cosker to Allenby and departed for 102, but after one further over, the elements intervened again as play was halted for twenty minutes for bad light.
Glamorgan took the new ball after 80 overs, but it led to a flurry of runs until in the penultimate over of the day Thilan Samaraweera was dismissed by Jim Allenby for 38 as Glamorgan secured a bowling point leaving Moeen unbeaten on 155.
