Ian Thomas. How can I begin with anyone else when a son of Newport has done something as special as Thomas did on Monday evening?

For it was truly special. A Twenty20 hundred, only the fourth ever, and on TV too. One only has to look at the calibre of the other three centurions in the competition to realise how remarkable Thomas' innings was.

They are Australians Ian Harvey and Andrew Symonds - two of the best one-day cricketers to grace the cricketing planet - and Graeme Hick, long renowned as a run machine with a special penchant for scoring centuries.

Thomas should feel mighty proud to be in a list alongside those.

And he deserves to be after his brutal assault upon the Somerset bowlers. It was an attack shorn of the likes of Andrew Caddick, Richard Johnson and Nixon McLean on a belter of a pitch with boundaries which were a little generous, but that should take nothing away from the sustained brilliance and cleanness of Thomas' hitting.

What's more, the runs came in a chase which eventually proved to be match- winning. That should also be taken into consideration because that in itself adds its own pressure. Not only did Thomas have to score a century, he had to win the game too.

I personally hope this proves a landmark innings for Thomas, the day he realised that he could cut the mustard with the big boys. Anyone who has played cricket against Thomas will know that he comes across as being a very confident, at times even cocky, cricketer.

But beneath that confident, sometimes brash, exterior I reckon there lurks a fair degree of nervous introspection and self-doubt, especially at the higher level. Hopefully this innings will have altered that a little.

Ok, it was only a Twenty20 match and in the grander scheme of things it is not wholly instructive, but what matters is that it is Thomas' first century for Glamorgan. And what it should do first of all is ensure that Thomas is found a place in the Totesport League side for the game against Northamptonshire on Sunday - even though Matthew Elliott will be back. I mentioned this last week, but this now only reinforces what I said.

Thomas' one day record is good - he averages over 30 - and his powerful hitting at the top of the order- which is where he should bat in one-day cricket, nowhere else - cannot be ignored.

Four-day cricket is another matter and Thomas still has much to prove in that. He still only averages just over 20 and even though he has told the press he thinks it harsh that he has been labelled a one-day player, his figures at the moment suggest that he is.

Opportunities may not present themselves immediately in four- day cricket because Jonathan Hughes must first have a run of games because only recently he scored a hundred and the other batsmen have all been in fine form.

Just ask Adrian Dale how hard it is to get back into the side. After a disappointing start to the season he was told to go away and score runs in the second team - the only trouble is that there is not a three-day second team game until August.

I think Thomas' best position in four-day cricket will be in the middle order. There he can just come in and play his normal, positive game. Whatever, it will be interesting to monitor his progress over the next few months. And whatever happens he can look fondly back upon a truly memorable Monday evening in Taunton.

And of course the good news is that Glamorgan have won their first two Twenty20 matches. After last year's debacle that is progress and it was interesting to hear on TV last week both David Lloyd and Jack Russell extolling Glamorgan's virtues and saying that they represented good value at 12-1 to win the competition.

That price may have come down by now. I also hear that they are 4-6 to win the Totesport League and one can understand why. The bookmakers generally know what they are doing. Glamorgan should win that league and they should gain promotion from the Second Division of the Championship.

People can point to the downturn of fortunes last season at a similar time after the break for the Twenty20, but hopefully Glamorgan will have learnt from that. And anyway they are winning in that competition this year. Last year it was a case of dented confidence.

Of course you would never have heard me making such wild presumptions when I was playing, but it is different now. I am a journalist and I can say what I think!
