Follow-on
In the game of cricket, a team who batted second and scored significantly fewer runs than the team who batted first may be forced to follow-on: to take their second innings immediately after their first. The follow-on can be enforced by the team who batted first, and is intended to reduce the probability of a drawn result, by allowing the second team's second innings to be completed sooner. The follow-on occurs only in those forms of cricket where each team normally bats twice: notably in domestic first class cricket and international Test cricket. In  these forms of cricket, a team cannot win a match unless at least three innings have been completed. If fewer than three innings are completed by the scheduled end of play, the result of the match can only be a draw. The decision to enforce the follow-on is made by the captain of the team who batted first, who considers the score, the apparent strength of the two sides, the conditions of weather and the pitch, and the time remaining. The rules governing the circumstances in which the follow-on may be enforced are found in Law 14  of the Laws of Cricket. Example. During the India national cricket team's 2017 tour of Sri Lanka, in the Second Test, India won the toss and batted first. Sri Lanka batted second, failed to score within 200 runs of India's first innings score, and were forced to follow-on. India won the match by an innings and 53 runs. This contrasts with the order of innings batted in the First Test of the same series, where Indian captain Virat Kohli had the right to enforce the follow-on, but declined. India won the match by 304 runs. Minimum  lead. Law 14 of the Laws of Cricket considers the length of the match in defining the minimum lead required for the defending team to enforce the follow-on. When the start of a match is delayed by one or more full days, e.g., due to bad weather, the score lead required to enforce the follow-on is reduced accordingly. However, when a match duration is shortened after it has started, the score lead required to enforce the follow-on remains unchanged. Enforcement. The follow-on is not automatic; the captain of the leading team decides whether to enforce it . Conventional theory suggests the follow-on is almost always enforced. In his classic text "The Art of Captaincy", Mike Brearley deals with the issue in a single paragraph, and finds the advantages overwhelming. However, there are several reasons for not enforcing the follow-on. In recent years there has perhaps been a trend against enforcing the follow-on in Test cricket. Former England captain Andrew Strauss on several occasions took his second innings straight away. It has, though, had some notable successes, for instance at Lord's in the 2009 Ashes series. Here, Australia were 210 behind on first innings  but did not follow on; England batted again, set Australia a highly unlikely victory target of 522, and won the game easily. For their part, Australian captains Steve Waugh and Ricky Ponting were also notably reluctant to enforce the follow-on, although that was perhaps more to do with wanting to allow Shane Warne to bowl on a deteriorating pitch later in the game. Michael Clarke only enforced the follow-on once in his career as a captain (during his final match in the 2015 Ashes), even when holding a substantial first innings lead due to the risk of tiring  his fast bowlers. Victories by sides not made to follow on. Test matches. South Africa v Australia, Kingsmead, 1950: In a four-day Test (with one rest day in the middle of the match), South Africa won the toss, chose to bat, and posted 311. The offspinner Hugh Tayfield took 7–23, helping to bundle out Australia for 75, giving South Africa a first-innings lead of 236. South African captain Dudley Nourse elected not to enforce the follow-on owing to forecasts of rain, but in their second innings South Africa folded for 99. Thanks largely to an unbeaten 151  from Neil Harvey, Australia made 336 in 123.6 overs to win by 5 wickets. First-class matches. ICC Intercontinental Cup – Afghanistan v Canada, Sharjah, 2010: Canada won the toss and chose to bat, scoring 566 in their first innings and bowling out Afghanistan for 264 in reply, giving Canada a first-innings lead of 302 runs. Wicketkeeper-captain Ashish Bagai, who retired hurt in Canada's second innings, declared with Canada on 191–4 after 40 overs to set Afghanistan a target of 494. The wicketkeeper Mohammad Shahzad made 214* as Afghanistan scored 494–4 to win by 6 wickets. Victories by  sides following-on. Test matches. There have been only three occasions in Test cricket where a team that was forced to follow-on won the match. Incidentally, Australia lost all three matches. 1894–95 Ashes. In the first innings of the First Test at Sydney, Australia had scored a massive 586 (Syd Gregory 201, George Giffen 161) and then dismissed England for 325. England responded with 437, leaving them ahead by 176. However, at stumps on the fourth day, Australia were 113 for 2 and looked to be the winners. But heavy rain fell overnight (in this era, pitches were not  covered between days of play), and next morning England's slow left-arm bowlers, Bobby Peel and Johnny Briggs, were all but unplayable. England dismissed Australia for 166, winning by 10 runs, and went on to win the series 3–2. Botham's Test: England v Australia, Headingley, 1981. In 1981, England's Ian Botham was performing poorly as captain against the touring Australians. The Australian team was rated as second only to the great West Indies team of the time, and contained a formidable pace attack in the form of Dennis Lillee, Terry Alderman and Geoff Lawson. After a loss  and a draw in the first two Test matches of the summer's six-test Ashes series, Botham resigned the captaincy. Mike Brearley, the captain Botham had replaced, resumed the reins for the third Test, at Headingley. This started out very badly: Australia scored 401 (John Dyson 102; Kim Hughes 89; but Botham took 6–95), and asked England to follow on after bowling them out for 174 (Lillee took 4–49; Lawson 3–32). The one bright point in the innings came from Botham, who top scored with 50 (his first since he had been made captain 13 matches earlier). In the  second innings, Botham came to the crease with England on 105 for 5, still 126 behind. Matters did not improve: Geoffrey Boycott and Bob Taylor soon followed, and with England 135 for 7 and still 92 runs behind an innings defeat looked likely. By all accounts, everyone on both sides thought the game was lost. Ladbrokes famously offered 500–1 against England winning the Headingley Test. When Graham Dilley joined him at the crease, Botham reportedly said, "Right then, let's have a bit of fun." Botham, with able support from the lower order, went on to make 149 not out , and gave England a slender lead of 129. The next day a fired-up Bob Willis took 8 for 43, and Australia slumped to 111 all out. India v Australia, Eden Gardens, 2001. Australia, who had won their 16 previous Test matches, including the first of the three-Test series between the two teams, had scored 445 in the first innings of the second Test and restricted India to 171; only V. V. S. Laxman (59) and Rahul Dravid reached 25 runs. The only other bright spot for India was the bowling of Harbhajan Singh, who took 7 for 123 , including a hat-trick (Ricky Ponting, Adam Gilchrist, Shane Warne). Australia then enforced the follow-on. Laxman came to the crease just before the end of Day 3 and proceeded to change the course of both the match and the series by hitting 281, at that time the record for an Indian Test batsman. He did most of his damage partnered with Dravid, who hit 180; the two were at the crease for the entire fourth day. India progressed to 657/7 in their second innings (a lead of 383), declared shortly before lunch on the final day (giving Australia insufficient  time to reach the total, thus securing at least a draw). By tea, Australia had scored 161/3, and a draw appeared the most likely result. Then, within minutes, Australia lost five wickets for 8 runs in a span of 31 balls. Harbhajan took the first two wickets in the same over, followed quickly by three wickets from Sachin Tendulkar. Australia proceeded to fall for 212 in the second innings and India won the match. Despite Harbhajan's prodigious bowling—6 for 73 to go with his seven-wicket haul from the first innings—Laxman was named man of the match. India 's 171-run victory was by far the largest of the three Test victories by the team following on (both of England's winning margins had been fewer than 20 runs), and it was the only time in history that a side has been able to declare the follow-on innings and still win. India under the captaincy of Sourav Ganguly went on to win the 3rd test, and hence the series, with Laxman contributing half-centuries in both innings and Harbhajan, who was named as man of the series for taking 32 wickets. First-class matches. County Championship – Warwickshire  v Hampshire, 1922. In 1922 at Edgbaston, Hampshire were bowled out for 15 in just nine overs in reply to Warwickshire's 223 in a 3-day match. Hampshire's total is the seventh-lowest score for a completed first-class innings. Hampshire were put back in to bat, and then famously scored a mammoth 521 before dismissing Warwickshire for 158 to win by a comfortable 155 runs. Hampshire's first innings total of 15 remains the lowest score for a completed innings by a winning team. In other sports. Some informal baseball games use variations of the follow-on
