Claire Velaski made her first start for Ellis Park and pitched all seven innings in an 8-3 loss to the Dodgers.
She later pitched two innings in relief in a 7-3 win over the Cardinals.
Also playing for Ellis Park was Junior Black Sox catcher Campbell Makea, part of the great softball family that includes long-serving Black Sox players Thomas and Fabian.
The younger Makea is studying health sciences at the University of Otago.
He returns to Wellington over the holidays to play for Poneke-Kilbirnie, but is expected back in Dunedin softball in February.
Makea showed his class by hitting home runs in both games he played.
Velaski, who is also a university student, has dispensation to play in the men's competition, along with Ellis Park team-mate Kate Brewerton.
Velaski removed the first two Dodgers batters she faced in the early game but then gave up a home run to the experienced bat of Scott Cartwright.
The Dodgers eased to a 4-0 lead but then Cartwright, in pitching mode, gave up three runs in the bottom of the fourth when Makea belted a homer with Brewerton and Adam Whelan on the bags.
Velaski found her control in the fifth and sixth innings, giving up no more hits and no more runs, but the Dodgers finished strongly with a 6-hit, 4-run seventh to seal the win.
Veteran Peter Mathieson got the start for Ellis Park against the Cardinals and got off to a shaky start when lead-off Dodgers batter Doug Hill hit a home run.
Ellis Park capitalised on two errors in the bottom of the second inning and got two runs, and took a commanding 5-2 lead when Makea smashed a two-run homer in the bottom of the fifth.
The Saints beat the Dodgers 6-2 in a third game that featured some outstanding pitching.
Cartwright retired the first seven Saints batters he faced, and Dodgers pitcher Sam Jones had excellent support from his defence as the game went scoreless through three innings.
Both teams scored twice in the fourth, with the Saints adding four runs - including a Mike O'Neill homer - over the final two innings.
Ellis Park, the Dodgers and the Saints are tied at the top of the competition.
