First season sires are always a point of interest throughout the summer as those in the bloodstock industry try and pre-empt which new stallions will swim and who may sink as the precocious two-year-olds start to show their hand.
Typically, in a game where you're essentially guessing until you see the horses on the track, there have been some stallions who have had a surprising amount of winners and then there are those who have so far failed to match expectations.
One stallion who may well fall into the latter category at this stage is Zoustar.
He isn't in theory a first season sire as he has already proved to be a great success in Australia, producing a large number of winners including at the top table.
However, he now has his first crop in the UK and his career in the Northern hemisphere hasn't got off to a sparkling start when looking at the two winners he has notched up in the UK but that is from a small sample size of just 13 runners and having seen his offspring at the sales, it was clear that plenty of them were big horses that may well need a bit of extra time.

It is very early days and his first crop in Australia didn't start to show their ability until the second half of the season so it would be no surprise to see him follow a similar trajectory here.
On the small evidence we have seen here in the UK, the most impressive of the two winners would undoubtably be Lezoo who recently won on debut at Bath. The Ralph Beckett trained filly scored in very cosy fashion from a field of rivals who had experience as well as beating a last time out winner into second.
She now holds a Listed entry at Newmarket this weekend where she will need to show improvement stepping up to 6f but she's a strong sprinting two-year-old and could be the early standout for her sire based on what we saw on debut.
Lezoo would under normal circumstances be the star performer on that midweek Bath card but she couldn't take that accolade as just 30-minutes later we saw Royal Acclaim win like a very good horse for the James Tate yard after a year off the track.
The three-year-old was a standout in the paddock, looking more like a colt rather than a filly due to her strength and she duly bolted up on the track as if she was doing a piece of work.
She now has entries in the Sapphire Stakes at the Curragh as well as options over here in the UK but Tate made it clear that the Nunthorpe would be his ideal aim and she's showing the early signs that group success could well be on the cards.
Keep an eye on Coyle's horse
Tony Coyle's Eye Up It's The Boss may not have the star potential of the above names mentioned but he has done what many can only dream of achieving in recent weeks as he clocked up a sequence of three wins and has climbed 18lbs in the handicap in the process.
Declared at Newcastle on Thursday to try and make it four on the bounce, he now needs to transfer his turf form to the all-weather for the first time but he is officially still very well in given that he will be running off his old mark with just a 5lb winners penalty to carry.
And when looking at how he won his most recent start at Redcar, there would be very few concerns given that he absolutely bolted in and is set to be hit with a massive 9lbs rise for his future runs.

The three-year-old was most recently steered to victory by 5lb claimer Kieran Schofield who doesn't get a huge amount of opportunities but will get the leg up on to Eye Up It's The Boss full of confidence with his last two rides being winning ones including when last seen aboard a remarkable 50/1 winner at Beverley.
Schofield was on board The Sara Ender trained Calcutus and won in the style that works once in a blue moon when pulling his way to a near 20-length lead and then just lasting home at the line - in the process becoming the trainers first ever winner on the flat.
Schofield will probably hope for a more conventional conveyance on Eye Up It's The Boss when seeking the four timer this week!
