Full tosses are rarely bowled deliberately, as they defeat the purpose of most types of delivery, which is to deceive the batsman by bouncing unpredictably on the pitch. They are commonly greeted with delight by a batsman, as they tend to be very easy to hit. A full toss is frequently the result of an error made while attempting to bowl a yorker. A yorker usually bounces at the batsmen's feet. Occasionally a full toss can surprise a batsman so effectively that he is unable to play it properly, and this can lead to a wicket, but few bowlers rely on this. There have been occasions in which a bowler intentionally bowls a full toss to achieve maximum swing into the base of the stumps. This was commonly seen with Waqar Younis and Wasim Akram of Pakistan, though recently Lasith Malinga of Sri Lanka has been bowling low full tosses with his unorthodox round arm action.
Full tosses below the waist are also commonly accidental. They can be caused by mistiming in the bowler's action as he attempts a yorker or changes his hand grip to produce a deceptive slower ball.
A full toss can also be used by a bowler to deliberately intimidate weaker, lower order batsmen.
