Ellyse Perry plays her 150th WBBL match as the unbeaten Sixers host the Renegades

Ellyse Perry will become the second Sydney Sixers player in four days to reach 150 WBBL matches when the unbeaten side meet the Melbourne Renegades at North Sydney Oval on Sunday

Perry, the first player the Sixers signed before the competition began in 2015, plays game No. 150 against the same opponent Ashleigh Gardner reached the mark against on Thursday night. The two are the only remaining members of the club's WBBL|01 squad.

The Sixers arrive unbeaten, with five wins from five and 10 points, second only to Perth Scorchers on net run rate. They have named an unchanged 13 for the 11am start.

The Renegades, sixth on four points, make one change, with Lucy Wilson coming in for Sara Kennedy.

Two foundation Sixers reach 150

Gardner was the sixth player signed to the inaugural Sixers squad, an 18-year-old who said at the time that the chance to play alongside Perry had decided her choice of club. Perry had been unveiled as the franchise's first signing at a launch on Sydney Harbour in July 2015.

Twelve seasons on, Gardner captains the side after Perry handed the role over following 10 years in charge.

"To play for the Sixers for 150 games is certainly something I'm really proud of, I absolutely love this club," Gardner said before Thursday's match. "It's an absolute honour to be able to lead this side and hopefully play quite a few more."

How Perry rebuilt her T20 game

Across the first seven WBBL seasons Perry averaged 50.16 but struck at 102.75, which was close to par in a competition where the average innings total sat around 120.

Since WBBL|08 her 1987 runs have come at an average of 49.35 with a strike rate of 131.51. In WBBL|11, her first season after giving up the captaincy, she averaged 51.5 and struck at 141.

"I haven't seen anyone work as hard as she has with her skills," Sixers allrounder Amelia Kerr said of Perry. "The game keeps evolving, and she keeps evolving."

Gardner's Golden Arm and the race for top spot

At the end of Thursday's win Gardner was presented with the Golden Arm cap as the leading wicket-taker of WBBL|12.

She is also in contention for the Golden Bat, having made a career-high 124 against Hobart Hurricanes and 64 not out off 25 against Sydney Thunder earlier in the season.

The Sixers' 10 points match Perth's, with the Scorchers ahead on a net run rate of 1.469 to 1.156. North Sydney Oval is where Gardner made her first Big Bash century, 114 from 52 balls.

Thursday's 11-run win still fresh

At Junction Oval the Sixers posted 140 and bowled the Renegades out for 129, with Kerr top-scoring on 53 from 34 balls and finishing with 1-29.

"It was a tricky wicket. We saw that throughout the day that it's hard to start," Kerr said. "So we knew that if we could get to 140, 150, we gave ourselves a good chance."

The Renegades slipped to 22 for 3 inside the fifth over before Tess Flintoff's 44 from 33 revived them. They needed 17 from the last over until Gardner's 3-13 closed the game out.

Renegades looking for a quick response

Two wins from five and a net run rate of -0.528 leave the Renegades sixth, three points adrift of the top four with the second half of the season to come.

Sophie Molineux, who had not passed single figures this season before making 18 on Thursday, again leads a squad containing Hayley Matthews, Deandra Dottin, Chloe Tryon, Georgia Wareham and Tayla Vlaeminck.

Sunday is the Sixers' Community Round fixture, and the second meeting between the sides in four days. Maddy Darke is unavailable for the hosts through injury, with Maitlan Brown and Elsa Hunter omitted.

Sydney Sixers and Melbourne Renegades begin at 11am AEDT on Sunday at North Sydney Oval, where Perry walks out for a 150th time in magenta.
