Andrew Flintoff's 16-year-old son Rocky blasted a quickfire century for the England Lions against Cricket Australia XI in Brisbane.
Flintoff junior, who signed his first professional contract with Lancashire in June, hit nine fours and six sixes in a 127-ball 108 while batting at number nine to swing the four-day match in the Lions' favour.
His father, on his first tour as Lions coach, watched as his son helped lift the Lions from 161 for seven to 319 all out for a lead of 105 in the first innings of the second day.
Cricket Australia XI reached 33 for one near the end by 72 runs with nine wickets remaining.
In the hosts' first innings, Lions bowler Pat Brown scored a hat-trick on his way to five for 21 as they recovered from 55 for four to reach 214 all out.
The Lions' recovery in response was also helped by opener Alex Davies' and Freddie McCann's 76 (51) but it was Flintoff, who turned 16 last April, who stole the show.

Flintoff was a late call-up to the Lions' tour after making a century for Lancashire's second XI in April before making his first-class debut in July.
The teenager's inclusion continued his impressive progress, having made his first-class debut for Lancashire in August.
He scored 32 in his first first-class innings for Lancashire against Surrey, becoming the 10th youngest debutant in the County Championship.
Flintoff received his first professional contract with Lancashire over the summer and has now played four first-class matches and seven list A matches.
He had caught the eye earlier this year by scoring a ton against Warwickshire in a second XI match in April, while he also scored a match-winning century for the England Under-19 team in July.
The England Lions' tour of South Africa is their first since their father Andrew was confirmed as coach.
The former England hero was signed on an initial 12-month contract in September.
