Australian pace bowler Michael Hogan took two late wickets as Glamorgan ended the first day of their LV= County Championship match against Hampshire at the Ageas Bowl with honours even.
Hampshire, recovering from a poor start after being put in, finished on 261 for six from 85.1 overs when bad light brought a premature end to proceedings.
Hogan dismissed Sean Ervine and nightwatchman Danny Briggs after Hampshire threatened a recovery.
Former Western Australian Hogan finished the day with creditable figures of 4-66, his victims including Michael Carberry as the in-form opener closed in on a century.
After the first hour was lost to rain, Glamorgan captain Mark Wallace gambled on fielding first and Hampshire were reduced to four for two.
The lively Hogan broke through at the end of the third over when home skipper Jimmy Adams edged to Wallace behind the stumps for a single.
Next man Liam Dawson made the same score before being trapped by John Glover in the sixth but Glamorgan's successes became much rarer as the wicket eased.
Carberry, particularly powerful in his county’s storming Friends Life t20 campaign but with a championship hundred in his last match against Kent, fell six short of another.
This was after he and Neil McKenzie put on 130 for the third wicket in 45 overs, each batsman taking advantage of Hogan's rest periods by punishing those that followed him.
Left-arm spinner Dean Cosker removed McKenzie to a catch at the wicket before Hogan returned to induce an edge behind from Carberry when within touching distance of his 29th first-class century.
Carberry hit 16 fours and always looked in control after a circumspect start but his departure only heralded another major partnership.
James Vince and Ervine added another 90 in 20 overs for the fifth wicket, taking the score to 246.
Ervine, as belligerent as ever, hit Hogan for three fours in an over but at the start of the next the bowler got his revenge thanks to a slip catch by Marcus North.
Briggs followed to Wallace's fourth catch of the day but Vince was in imperious form, reaching a half-century just before the close and ending 51 not out from 98 balls.
