BIRMINGHAM, June 12: England must improve on the Test performances against West Indies if they are to succeed in their next challenge against South Africa, according to captain Andrew Strauss.

Strauss's team sealed a 2-0 series win over West Indies on Monday after the rain-affected third and final Test was abandoned as a draw.

England dropped four catches in one innings and allowed the last-wicket pair of Denesh Ramdin (107 not out) and number 11 Tino Best (95) to share a stand of 143.

The three-match South Africa series, which starts at The Oval on July 19, will decide whether England remain top of the world rankings or the Proteas leapfrog them.

“We go into our next Test assignment in pretty good fettle and feeling pretty confident,” Strauss told reporters. “We are also aware there are definitely areas in which we need to improve.

“It wasn't a perfect performance by us in the little play we did have here and that is frustrating. We dropped a few catches.”

No play was possible in three of the five days in the third Test at Edgbaston, England reaching 221 for five in reply to West Indies first innings 426. “We found ourselves under a bit of pressure with the bat but there were still some good performances,” said Strauss.—Reuters
