Question: Aaron Heal is a cricketer who took over as spinner from left-arm wrist spin bowler, and a lower-order left-handed batsman, born on what day?

Context paragraphs:
Aaron Heal: Aaron Keith Heal (born 13 March 1983) is an Australian cricketer who played domestically for Western Australia and later the Melbourne Renegades.  A left-arm orthodox spinner and capable lower-order batsman, Heal debuted during the 2003–04 season, and played in the team that won that season's ING Cup.  He established himself in Western Australia's first-class (Sheffield Shield) and limited-overs (Ford Ranger Cup) sides during the 2006–07 season, taking over from Brad Hogg as the team's primary spinner, but was selected less regularly over the following seasons.  Heal's last first-class and one-day matches came during the 2010–11 season, but he was a regular when the team played in the KFC Twenty20 Big Bash, maintaining both a low economy rate and a low bowling average.  His performances at Twenty20 led to his naming in Australia's initial 30 man squad for the 2009 ICC World Twenty20.  Heal signed with the Melbourne Renegades for inaugural season of the Big Bash League, playing four matches.

Brad Hogg: George Bradley "Brad" Hogg (born 6 February 1971) is an Australian cricketer.  He is a left-arm wrist spin bowler, and a lower-order left-handed batsman.

Left-arm unorthodox spin: Left-arm unorthodox spin, also known as slow left arm chinaman, is a type of left arm wrist off spin bowling in the sport of cricket.  Left-arm unorthodox spin bowlers use wrist spin to spin the ball, and make it deviate, or "turn" from left to right after pitching.  The direction of turn is the same as that of a traditional right-handed off spin bowler; however, the ball will usually turn more sharply due to the spin being imparted predominantly by the wrist.

Ellis Achong: Ellis Edgar "Puss" Achong (16 February 1904 – 29 August 1986) was a sportsman from Trinidad and Tobago in the West Indies.  He played cricket for the West Indies and was the first person of known Chinese descent to play in a Test match.  Left-arm unorthodox spin (left-arm wrist spin) is sometimes known as "slow left-arm chinaman" (SLC) which is thought to be in his honour.

Leg spin: Leg spin is a type of spin bowling in the sport of cricket.  A leg spinner bowls right-arm with a wrist spin action, causing the ball to spin from right to left in the cricket pitch, at the point of delivery.  When the ball bounces, the spin causes the ball to deviate sharply from right to left, that is, away from the leg side of a right-handed batsman.  The same kind of trajectory, which spins from right to left on pitching, when performed by a left-arm bowler is known as left-arm orthodox spin bowling.

Vasant Tapu: Vasant Tapu Harji Chavda, usually known as Vasant Tapu (1936-1988) was a Tanzanian cricketer.  A left-handed batsman and left-arm fast-medium/left-arm orthodox spin bowler, he played for the Tanzania national cricket team between 1967 and 1974 and also played first-class cricket for East Africa.

Bobby Peel: Robert Peel (12 February 1857 – 12 August 1941) was an English professional cricketer who played first-class cricket for Yorkshire between 1883 and 1897.  Primarily a left-arm spin bowler, Peel was also an effective left-handed batsman who played in the middle order.  Between 1884 and 1896, he was regularly selected to represent England, playing 20 Test matches in which he took 101 wickets.  Over the course of his career, he scored 12,191 runs and took 1,775 wickets in first-class cricket.  A match-winning bowler, particularly when conditions favoured his style, Peel generally opened the attack, an orthodox tactic for a spinner at the time, and was highly regarded by critics.

Alan Keith Davidson: Alan Keith Davidson, AM, MBE (born 14 June 1929, Lisarow, Gosford, New South Wales) is a former Australian cricketer of the 1950s and 1960s.  He was an all rounder: a hard-hitting lower-order left-handed batsman, and an outstanding left-arm fast-medium opening bowler.  Strongly built and standing six feet tall, Davidson was known for his hard hitting power, which yielded many long hit sixes.  His left arm bowling was a mainstay of the Australian pace attack of the 1950s and early 1960s, and from the late 1950s widely regarded as one of the finest pace bowlers in the world, with a classical bowling action which imparted late swing.  Davidson was considered along with Wasim Akram as one of the two greatest left arm fast bowlers in history, and bowled with great control, conceding less than two runs per over.  Only two other post-war bowlers have a superior bowling average.  Davidson was known for his anticipation in close catching positions and his accurate and strong throwing arm from the outfield.  His ability to take improbable close range catches saw him earn the nickname "The Claw".

Wrist spin: Wrist spin is a type of bowling in the sport of cricket.  It refers to the cricket technique and specific hand movements associated with imparting a particular direction of spin to the cricket ball.  The other spinning technique, usually used to spin the ball in the opposite direction, is finger spin.  Wrist spin is bowled by releasing the ball from the back of the hand, so that it passes over the little finger.  Done by a right-handed bowler, this imparts an anticlockwise rotation to the ball, as seen from the bowler's perspective; a left-handed wrist spinner rotates the ball clockwise.

Slider (cricket): In cricket, a slider is a type of delivery bowled by a wrist spin bowler.  Whereas a topspinner is released with the thumb facing the batsman, a slider is bowled in a similar manner to a legbreak, but instead of imparting sidespin with the third finger, the bowler allows his fingers to roll down the back of the ball, providing a mixture of sidespin and backspin.  Whereas a topspinner tends to dip more quickly and bounce higher than a normal delivery, a slider does the opposite: it carries to a fuller length and bounces less than the batsman might expect.  The sliders will typically head towards the batsman with a scrambled seam (with the ball not spinning in the direction of the seam, so the seam direction is not constant, unlike in conventional spin bowling).  This has less effect on the flight and bounce but absence of leg spin may deceive the batsman.  Frequently the slider is bowled with a mixture of side spin and backspin.  This has the effect of making the ball harder to differentiate from the leg break for the batsmen without reducing the mechanical effects caused by the backspin.  This delivery may skid straight on or it may turn a small amount.
