Rennie's second-placed Kobe Steelers side continued their march towards the Japan Rugby League One playoffs with another easy win on Saturday.
Kobe, who last won the title in 2018, hammered ex-Wallaby Sean McMahon's Tokyo Sungoliath 49-28.
In doing so, the Kansai-based side are the first to surpass 100 tries for the season, with the former Wallaby boss's charges having scored 105 - that's 23 more than the only side ahead of them on the points table, Saitama Wild Knights.
While operating the league's best defence has been the foundation on which the Wild Knights have risen to the top, they cut loose on Saturday, flattening Sagamihara Dynaboars 57-19.
Four tries in the final 10 minutes saw the third-placed Spears Funabashi Bay to a 54-21 win over Mie Heat, with Wallaby Bernard Foley, who will leave the club at the end of the season, back from injury.
The continued demise of Brave Lupus is a major talking point, after the two-time defending champions crashed to a 50-26 defeat against 10th-placed Yokohama Eagles, who scored 19 points in the 10-minute absence of their yellow-carded All Black flyhalf Mo'unga.
Brave Lupus are clinging on to the sixth and final playoffs position by two points, but eight defeats from their past 10 matches doesn't read like finals form.
In other results, Shizuoka BlueRevs beat Urayasu D-Rocks 49-26, and Verblitz prevailed 40-28 over BlackRams Tokyo.
