Ambrose led the way as the Bears made up for lost time - after Wednesday was completely washed out - by piling on 158 runs in 30 overs this morning. Ambrose moved from his overnight 64 to be unbeaten on 122 and, with Ian Blackwell reaching his half-century from 40 balls, accelerate Warwickshire to 456 for six.
