His place in the Australian team questioned like never before, Ricky Ponting responded strongly with back-to-back fifties in the ongoing first Test against India but the veteran is more disappointed than happy as he could not convert them into hundreds.

"It's nice to get a few runs. But when you get past 50 as a top-order batter, it's your job to go on and make big scores," Ponting, who has scores of 62 and 60 in the evenly-poised match, said after the third day's play here.
