Leading the batting leaderboard is Central allrounder Jason Trembath, who has smashed 148 runs with a top score of 92.
Tauranga Boys' College mentor Mark Orchards is second with 109 runs and a highest score of 84no.
Te Puke stalwart Stephen Crossan scored a neat century to grab third place.
Mount Maunganui allrounder Alex Gooding leads the way in the bowling stakes with seven wickets and best figures of 3-21. Teammate Dan Hill is second with six bowling scalps including a remarkable 3-2.
The key match-up in the early afternoon round at Fergusson Park is an inter-city battle between Cadets and defending champions Central. In other round five matches, Greerton square off with Whakatane United, Mount Maunganui meet Tauranga Boys' College and BOP Indians face Te Puke.
Cadets will have little respite on the day, with Greerton in the late afternoon round. The two Western Bay sides have a healthy rivalry, that stretches back several decades, and could produce a real battle of attrition.
The winner of the BOP Indians match with Whakatane United will grab their first win of the competition. Mount Maunganui and Te Puke will resume hostilities with Central meeting Tauranga Boys.
