(of a bowler) during the bowling action, the last foot to contact the ground before the ball is released. Front foot contact
during the bowling action, the position of the bowler when their front foot lands on the ground. Fruit Salad
when a bowler delivers a different type of delivery each time, rather than bowling a constant speed, length and angle. Fruit salad bowling is used most commonly in Twenty20 to prevent batsmen from getting comfortable. (Full) face of the bat
references the front, or flat side, of the bat, particularly where the manufacturers insignia is written. A batsman is said to have given a bowler or a delivery faced the full face of the bat if they have middled the ball and driven it straight down the wicket, such that the bowler clearly sees the manufacturers insignia. Full length
a delivery that pitches closer to the batsman than a ball pitching on a good length, but further away than a half-volley. Full pint
when a stump is knocked completely out of the ground by a delivery. Full toss (also full bunger in Australia)
a delivery that reaches the batsman on the full, i.e. without bouncing. Usually considered a bad delivery to bowl as the batsman has a lot of time to see the ball and play an attacking shot. Also, it does not have a chance to change direction off the ground, making it the ultimate crime for a spin or seam bowler. Furniture
another term for the stumps.
