Pakistan's teenage paceman Mohammad Aamir and off-spinner Saeed Ajmal impressed with the ball after their side's batsman had dominated Tasmania in the tour match at Bellerive Oval.
Chasing Pakistan's first innings 437 the Tigers were 6-132 at stumps on Sunday.
Tigers skipper George Bailey said the 17-year-old Aamir bowled quickly and moved the ball nicely on a pitch not known for pace.
"Young Aamir was pretty impressive," Bailey told reporters after day two of the three-day warm-up.
"That's probably as quick as we've faced all year and he got a bit of reverse swing at the end.
"Obviously the spinner Saeed Ajmal has got some pretty good skills, a good doosra and some good change-ups which for this wicket, which doesn't turn much or offer much, he's getting the odd one to bounce and kick and spin the other way."
The exciting paceman Aamir (2-18 off 10 overs) bowled with venom, taking two wickets in his first four overs without giving away a run, while tall quick Abdul Rauf (2-21 off 12 overs) also impressed.
Aamir, who says Adam Gilchrist is his playing hero, was happy that he was able to bowl a fuller length against the Tigers after working on that aspect with coaches.
And he's confident of performing well on Boxing Day.
"I'm in a learning process. I'm not a complete cricketer. I'm learning day by day," he told reporters.
"I think the main thing is patience. If you are in control and patient then you will succeed but not be thinking about the crowd (at the MCG)." Aamir says he bowled up to 152km/h in the New Zealand Test series but averages 145km/h.
"But the main thing is line and length," he added.
Pakistan appear to be well and truly warmed up for the Test series.
Ajmal succeeded where Tiger Jason Krejza failed by taking a tidy 2-56 from his 18 overs.
Earlier the tourists had piled on the runs, wicketkeeper Kamran Akmal (109) cracking a stunning century off 74 balls, adding to Salman Butt's tenacious 153 on day one.
Although Krejza took three wickets, the Pakistani batsmen took a shine to his bowling, taking 162 runs from his 28.4 overs, including 21 fours and five sixes.
Test hopeful Brett Geeves was the pick of the bowlers with one wicket (Butt) for 37 runs from 22 overs, including seven maidens.
With the bat, Bailey (50) rued missing the opportunity to notch a big score while his teammates appeared uncomfortable with the rise in class.
He was the only Tiger batsman to look at relative ease against the dominant Pakistan attack before being judged lbw off the bowling of Ajmal.
"I felt good. I was fairly disappointed to get out there with four or five overs to go but I was feeling as good as I ever have," Bailey said.
"It was a good opportunity today and it would have been nice to be 55 not out at the end of the day."
In other news, Australian swing bowler Ben Hilfenhaus had a net session at Bellerive on Sunday morning, with Tigers officials saying he's pulled up well after taking 4-18 off eight overs for his Hobart club side on Saturday.
Knee tendonitis has forced him out of the last two Tests.
The first Test against Pakistan begins on Boxing Day in Melbourne.
