[2] Western Australia hosted the 2007 Claxton Shield tournament at Tom Bateman Reserve, with games also being played in the nearby regional centres of Rockingham and Mandurah.

In 2008, it won the Southern Division with an 8–4 record and swept New South Wales in the best-of-three semi final series in Sydney.

With the game set for extra innings, outfielder Daniel Floyd hit a walk-off single to deliver back-to-back titles for Perth.

The ABL, which is partly funded by Major League Baseball features six teams, Sydney Blue Sox, Melbourne Aces, Canberra Cavalry, Brisbane Bandits and Adelaide Bite.

2008 Claxton Shield MVP Clint Balgera returned to the team after sitting out the last two seasons,[5] while pitching prospect Liam Baron is another key acquisition, with the former collegiate pitcher expected to lead the Heat's rotation.

Allan de San Miguel, Warwick Saupold, Daniel Schmidt and Mitch Graham, who have been some of the Heat's most significant players in recent Claxton Shield seasons, as well as Jesse Baron, Clint Knight, Brandon Dale, Aaron Bonomi and Tyler Anderson have also signed on for the upcoming season.

[6] However, 2009 MVP and former Los Angeles Angels of Anaheim minor league centre fielder Nick Kimpton is leaving the Heat to return home to play for Canberra, while Tim Kennelly will miss the first half of the season after it was announced he will be sent to the Arizona Fall League by the Philadelphia Phillies.

[7] In early October, Perth announced a deal with the Baltimore Orioles, which saw the Major League Baseball outfit send four of their top prospects to play for the Heat during the first ABL season.

Left-handed starter Cole McCurry, right-handed reliever Brett Jacobson and outfielders Ronnie Welty and Robbie Widlansky were the prospects Perth secured.

[8] The Heat started the 2010–11 season with a loss to the Brisbane Bandits, but quickly bounced back by winning the final three games of the series.

Perth's season hit a snag when they lost every match of a four-game series to the Sydney Blue Sox but bounced back emphatically.

The Heat won their next eight games before splitting the final home series against the Melbourne Aces to finish the regular season in second position.

Among the highlights of the season were Widlansky, who led the league in hits with 52, and Daniel Schmidt, who was tied with Brisbane's Chris Mowday for most wins (six).

[11] The Perth Heat began the 2011–12 season with an ABL record-breaking 11–0 November with three consecutive series victories against the Adelaide Bite, Melbourne Aces and Sydney Blue Sox.

With a classic pitchers' duel in the making, the bottom of the fourth saw James McOwen hit a home run to break the tie and to give the Heat a 2–1 lead.

Game one was a close contest with Sydney mounting a four-run comeback, but it wasn't enough as the Heat held on by one run to win 5–4.

[14] In Manager Kevin Boles' final season at the helm, the defending champion Heat went 23–33 to finish in fifth position and miss the playoffs.

Following the appointment of new Manager Andy Kyle, who replaced Matt Kennelly, the Heat compiled a 26–14 record to finish second in the ABL standings behind the Brisbane Bandits.

[17] Led by Tampa Bay Rays prospects and future major leaguers Jake Fraley and Mike Brosseau, alongside local young-guns Jess Williams and Robbie Glendinning, the Heat re-established themselves as a powerhouse of Australian baseball.

Despite losing star first baseman Luke Hughes to the Melbourne Aces, the Heat opened the season with an impressive 4–0 series sweep of newly formed expansion side, the Auckland Tuatara.

[20] The Heat went on to finish with a 24–16 record – good enough to pip the Aces to the South-West crown and return to the playoffs for a second consecutive year.

With their season on the line, the Heat then produced a solid offensive performance to defeat the Blue Sox 11–6 in the deciding Game Three and book their spot in the ABL Championship Series.

[20] Heat outfielder Tim Kennelly was named the recipient of the Helms Award, while Robbie Glendinning won the league's Rookie of the Year.

On 1 August 2019, it was announced that former manager Brooke Knight would return to for the 2019–20 Australian Baseball League season, replacing Andy Kyle.

On the same day it was announced Kyle would remain at the Heat as an assistant coach alongside former Perth pitcher Tyler Anderson and Kevin Hooker.
