Hampshire captain Dimitri Mascarenhas has demanded an improvement while he is playing for the Rajasthan Royals in the Indian Premier League.

Mascarenhas leaves for a fortnight with the IPL franchise tomorrow following an innings-and-27-run defeat for Hampshire against Yorkshire at Headingley today.

It was Hampshire's first defeat against Yorkshire in nine Championship matches and their heaviest for eight years.

After resuming their second innings on 136-4, still needing 103 to make Yorkshire bat again on the final day, Hampshire were dismissed for 212, having suffered defeat in their opening Friends Provident Trophy game against Somerset last week.

Mascarenhas said: "It's not nice to leave on the back of two losses, I didn't want to do that, but we didn't bowl as we would have liked to.

"Yorkshire showed us how to bowl, they got it in the right area by pitching it up and swinging it so we've got to pull it back for the next game.

"The batters also need to start getting some big scores as we haven't had a hundred yet."

Mascarenhas added: "I'm trying to perform with bat and ball as well as captain and it's tough when we get pumped like this."

Hampshire were frustrating Yorkshire while Nic Pothas and Michael Brown were at the crease on Saturday morning.

But Pothas, having been dropped on 37 by Yorkshire captain Anthony McGrath at second slip, was bowled via a huge inside edge without adding to his score in the next over.

Then, in the penultimate over before lunch, Michael Brown was caught by first-slip Jacques Rudolph for a stoic 81 after edging an attempted drive against Ajmal Shahzad.

Hampshire still needed 48 runs to avoid an innings defeat at lunch but continued to struggle against the swing generated by Yorkshire's pace attack and lost their last four wickets for 19 runs in 8.5 overs after the interval.

Mascarenhas (22) edged a loose drive and wicketkeeper Gerard Brophy took another excellent catch to see off Chris Tremlett (8) before Greg Lamb (8) nicked to first slip.

It was all over when Shane Bond (1) lost his middle stump to England discard Matthew Hoggard, who finished with a match analysis of 8-97.

Hampshire play two Friends Provident Trophy games without Mascarenhas next weekend.

They then travel to Taunton to play Somerset without England Lions pair Michael Carberry and Chris Tremlett, as well as Mascarenhas.

Mascarenhas said: "It's a blow but we'll have KP back for that game and David Balcombe will hopefully be available for selection by then because he's playing a Championship match for the second XI at Surrey on Wednesday."

Hampshire have confirmed that Pothas will captain the Hawks in the three FP Trophy games that Mascarenhas will miss - against Somerset, Gloucestershire and Worcestershire - while Jimmy Adams will skipper against Somerset at Taunton in the Championship from May 7-10.

Mascarenhas's Rajasthan Royals debut is likely to be against the Kolkata Knight Riders on Thursday.

That is the first of five Indian Premier League matches he is available for during the next fortnight.

He said: "I'm really looking forward to getting over there, it will be good fun."

Mascarenhas returns to Hampshire for the Championship match against Surrey at the Rose Bowl, which starts on May 14, but could also miss the visit of Kent if the Rajasthan Royals reach the semi-finals at the end of May.
