Batters Colin Ingram (145*) and Eddie Byrom (105*) shared an unbeaten stand of 253 for the 2nd wicket as Glamorgan pummelled the Sussex bowlers on day two of their LV= County Championship clash at Sophia Gardens.
It was Ingram’s fifth first-class century for Glamorgan and first since 2017, while Byrom registered his maiden hundred for the Welsh county.
By the close, they took Glamorgan to 258 for one in reply to Sussex's 376 all out.
"I had a really good pre-season doing some of the hard yards (for red-ball practice) so I thoroughly enjoyed it out there,” said Ingram.
"Playing here before many years before, there were things I could bring back into my game and I've always just enjoyed playing, switching between formats is a great challenge. I put the work in and it was great to reap some rewards.
"I looked to score against the new hard ball, it came on quite nicely so i got a few opportunities early, I looked to be busy and keep it quite simple.
"It was brilliant to be out there with Eddie in a long partnership, when he got into the nineties I was almost more nervous for him than I'd been but he played terrifically well.
"They've got a lot of runs on the run so we'll have to dig in with a good start in the morning and see where the game flows, but we've got good momentum in the game."
