This World Group II is such a hard group to get out, there are so many good quality players in there. I remember in my day coming up against the likes of Denmark's Caroline Wozniacki and the Radwanska sisters of Poland.

A nice game in the end for Begu and she stretches that neck out.

It doesn't seem to have affected her so far though.

A second double fault for Begu, in only her second service game, hands Watson the first point of the game.

But she follows it up with an ace. A topsy-turvy start for the Romanian, who missed yesterday's singles with a stiff neck.

Heather Watson overcooks her forehand and it's a third break of serve in a row.

Begu goes back in front, 2-1.

The crowd are slightly more subdued in this one.

Their superstar Simona Halep got the business done this morning in front of a raucous crowd, but they're not as pumped up for this one.

And Watson is keeping them quiet. She stays low and powers a forehand down the line.

But Begu brings up another break point.

She's done it.

Begu's shot goes long, and after an inspection from the chair umpire, the break is confirmed.

Both players lose their opening service games and we're back to 1-1.

Watson is taking charge in this second game.

She's got two chances now to get the break straight back.

But that's better from Watson.

A long rally which she finishes in style. The drop shot brings Begu forward and Watson backs it up with a brilliant stroke down the middle.

Begu has to duck to avoid her head being taken off.

Much more like it.

And Begu breaks in the first game, just like Halep did against Konta.

A couple of unforced errors to start from Watson.

Her second shot finds the net and a super shot from Begu hands the Romanian three break points.

A shaky opening from the Brit, but that's more like it.

A brilliant forehand winner and she's saved one of the three break points.

We're under way.

Heather Watson serves first...and sends her first forehand long.

Begu wins the first point of the game.

BBC Sport commentator Peter Odgers: Heather Watson seems to embrace playing in this big-match environment and that shows in her Fed Cup record. She has 25 wins and seven losses in total with 17 wins and six losses in singles. 

She is the type of player who will enjoy this type of crowd and situation.

You don't just have to listen to me this morning.

We've got pictures for you too.

Remember, Great Britain are trying to progress from the Europe/Africa Zone Group I for the first time in 24 years.

They are close to a place among the Fed Cup elite, but if Watson loses, they'll stay in the zonal group.

The players are out on court. Warm-ups to come, then we're off!

So where does that leave us?

Heather Watson now has to win her singles match against Irina-Camelia Begu to keep GB in the tie and take it to the final game, the doubles.

Begu has a singles ranking of 33, while Watson is ranked 113. A tough ask for the Brit.

Five minutes to go until the second game of the day.

If you're just joining us, GB have lost the first singles rubber of the day in Constanta.

Simona Halep beat Johanna Konta 6-1 6-3 to give Romania a 2-1 lead.

A classy performance from Simona Halep, who was superior in every department. She has just indicated in a TV on court interview that she really liked her chances today - as she feels she has "dominated" previous matches against Konta, despite losing both.

Big job now for Heather Watson against Irina-Camelia Begu, who missed yesterday's matches but was warming up on court earlier.

Watson was also easily beaten by the formidable Halep in yesterday's singles.

The Brit, ranked 113, struggled to cope with her rival as she lost her serve twice to love in the second set.  

Romania go back into the lead but GB have a chance to level proceedings in the next singles rubber.

Stay tuned as Heather Watson takes on Irina-Camelia Begu in the next 20 minutes.
