circle for the first six overs. Women's Fielding Restriction Circles In the Women's game the infield and close infield circles are smaller than in the Men's game. With the semicircles of the infield having a radius of and the close infield circles having a radius of . The restriction of having a maximum of three fielders in the outfield is applied for a further two blocks of five overs, with the captains of the fielding and the batting sides deciding the timing of one block each. These five-over spells are called Powerplay 2 and Powerplay 3 and may be shortened if the length of the innings is restricted (Powerplay 1 is the first block of 10). Powerplays were first encountered in the One Day International between England and Australia on 7 July 2005. For the rest of the innings, a more generous maximum of five fielders in the outfield applies. History Fielding restrictions were first introduced in the Australian 1980-81 season. By 1992, only two fieldsmen were allowed outside the circle in the first fifteen overs, then five fieldsmen allowed outside the circle for the remaining overs. This was shortened to ten overs in 2005, and two five-over powerplays were introduced, with the bowling team having discretion over the timing for both. In 2008, the batting team was given discretion for the timing of one of the two powerplays. In 2011, the teams were restricted to completing the discretionary powerplays between the 16th and 40th overs; previously, the powerplays could take place at any time between the 11th and 50th overs. On October 30, 2012, changes to the rules for fielding restrictions in one-day matches were officially implemented by the ICC. The number of Powerplay blocks were reduced to two; the first occurs within the first 10 overs, restricting the team to two fielders outside the 30-yard circle. The second block, the Batting Powerplay with a restriction of three fielders outside the circle, must occur by the 40th over. The number of fielders outside the 30-yard circle in non-Powerplay overs has also been reduced to four (from five). In June 2015 rules changed to do away with batting powerplay, and allowed up to 5 fielders outside the circle in last 10 overs. The 2015 rule changes also included the removal of batting power play. Twenty20 The number of players in the outfield area is the same as for the One-day
