UPDATE 1-Soccer-Croatia cling to second spot with Ukraine draw

(adds details)

ZAGREB, June 6 (Reuters) - Croatia's grip on second place in World Cup qualifying Group Six slipped on Saturday when they had to come from behind to grab a 2-2 draw with Ukraine.

Mladen Petric had given Croatia an early lead only for goals from Andriy Shevchenko and Olexiy Gai to put Ukraine in charge.

Croatia looked lost before Mario Mandzukic's introduction as a substitute gave them the boost they needed.

Luka Modric played a one-two with Mandzukic on the edge of the box and his powerful shot took a deflection on its way in.

Petric and Modric both hit the frame of the goal as Croatia pressed for a winner.

England top the standings with a maximum 18 points from six games following their 4-0 win in Kazakhstan earlier in the day.

Croatia remain second on 11 points from six but Belarus, third on nine points, and Ukraine, fourth on eight, each have a game in hand and look threatening.

The group winners qualify for the finals while the best eight runners-up from the nine groups go through to a playoff.
