When an arm ball trapped Sachin Tendulkar plumb in front to give Mudhsuden Singh Panesar, aka Monty, his first Test wicket, his mad-as-a-march-hare celebration was lovely to watch. The List this week looks at the most valuable first wickets in Tests. The calculation is based on the batsman's aggregate at the start of the game.

Panesar's wicket of Tendulkar, who had 10,386 runs at the time, at Nagpur is a shoo-in at the top of the list. On Sri Lanka's tour of India in 1986-87, debutant Graeme Labrooy had Sunil Gavaskar caught for 176 as his first Test wicket in the first Test at Nagpur. In the next Test, part-timer Asanka Gurusinha also opened his wicket-tally with Gavaskar's scalp.

As Steve Waugh began the conquest of his `final frontier' with a ten-wicket rout of India at Mumbai, he became Rahul Sanghvi's first wicket. Sanghvi went on to dismiss Shane Warne as well with his left-arm spin, but conceded 67 runs in 10.2 overs. He hasn't played another Test since.

Of Test cricket's 15 leading wicket-takers, only Imran Khan went wicketless in his debut game. He bowled 28 overs without success in the drawn first Test of Pakistan's tour of England in 1971. He faced three years on the sidelines after that and returned for Pakistan's 1974 tour of England and took three wickets at Leeds, Tony Greig being his first.

The most valuable first wicket in terms of the average of the batsman dismissed belongs to Norman Yardley who returned after an eight-year rest to take the wicket of Don Bradman, then aggregating 5280 runs at 99.62, in his third Test.

Given that Tendulkar has held the record for most ODI runs for several years now, he expectedly holds the top two spots on the the ODI list as well for being the most valuable wicket.
