The CPBL's second-half race enters Sunday with a half-game gap after the Rakuten Monkeys' sweep, and the league's three-game slate puts its marquee matchup under the roof at Taipei Dome: the TSG Hawks against the Uni-President 7-Eleven Lions.

The Global Sports Archive schedule for Sept. 27 lists three games: Fubon Guardians at CTBC Brothers at Xinzhuang, Rakuten Monkeys at Wei Chuan Dragons at Tianmu, and the Hawks at the Lions at Taipei Dome. The Dome game is listed for 09:05 UTC, which is 17:05 Taipei time. The Xinzhuang game is listed for 11:05 UTC, or 19:05 Taipei time. The Tianmu first pitch was not included in the schedule feed.

Three games, three different pressures

At Xinzhuang, the Guardians and Brothers meet in one of the day's two outdoor games. The matchup pairs two northern fan bases, and the first pitch is listed for 19:05 local time.

At Tianmu, Rakuten visits the Dragons with a chance to build on the sweep that pulled the Monkeys within a half-game. The Dragons' home park is open-air, so the weather matters. That is one reason the Dome game carries a different feel: no rain delay, no heat index, no wind blowing out or in.

The night's centerpiece is at Taipei Dome, where the Hawks and Lions meet in the controlled environment that has become the CPBL's biggest regular-season stage. The Dome game is the only one on the card that cannot be affected by rain or the typhoon offshore. That does not make it easier. It puts the focus on pitching, defense, and the small margins that decide close games.

What the half-game gap means

SETN reported Sept. 25 that Rakuten's second-half deficit stood at a half-game entering the weekend after the Monkeys completed a sweep. That margin is thin enough that a single Sunday result can flip the order. In the CPBL's half-season format, the second-half standings carry playoff weight, so every game in the final stretch is not just about the overall record. A half-game lead is not a tie: it reflects one fewer loss or one more win, and it can disappear before the weekend is over.

For Rakuten, the task is straightforward: keep winning and make the teams above them feel the pressure. For the teams ahead, Sunday is about avoiding the kind of loss that turns a small cushion into a tie. With three games on the card, the second-half table can move in several directions before the day is done.

Dome baseball vs. outdoor weather

The CWA forecast for Sept. 27 included a moderate Typhoon Surigae offshore and temperatures up to 36°C in western Taiwan, with a northeast monsoon expected to bring cooler, wetter conditions north by Oct. 1. For the outdoor games at Xinzhuang and Tianmu, heat and possible rain are part of the game plan. For the Hawks and Lions, the Dome removes those variables and puts the focus on the field, the mound, and the bats.

The Dome also changes how teams manage a series. Players do not have to worry about a rain delay or a heat index; the game starts on time and the conditions stay stable. That can help pitchers who rely on grip and command, and it can help hitters who prefer a consistent backdrop. It also makes the venue a natural fit for a late-September game that will not be interrupted.

What to watch

The schedule feed lists only the matchups; starting pitchers and lineups are announced separately. That means the biggest pregame question is which arms each team will send to the mound, and whether any of the weekend series will be decided by bullpen depth. The second-half race adds another layer: Rakuten's sweep has made the standings tighter, and the Monkeys' game at Tianmu is the one most directly tied to the half-game gap.

For the players, Sunday is the last day of the weekend series, with travel and recovery ahead. For the league, it is a chance to show its full slate: three parks, three games, and one scoreboard. The first pitch at Taipei Dome is set for 17:05 local time, and the Xinzhuang game is set for 19:05. The Tianmu game completes the card. All three results will be read together.

The schedule remains as listed: three games, three first pitches, and a second-half race separated by a half-game. Sunday's slate is the next chance to see which way the race is trending.
