Australian co-vice-captain Pat Cummins says there's competition for places in Australia's bowling attack
Cummins believes there could be some changes to their bowling attack for the second Ashes Test against England at Lord's on Wednesday.
In Saturday's rain-affected warm-up match at Worcester, Josh Hazlewood took 3 wickets, with 2 each from Mitchell Starc, Michael Neser and Marnus Labuschagne.
