# 2021 Chinese Professional Baseball League season

The 2021 Chinese Professional Baseball League season was the 32nd season of the Chinese Professional Baseball League, with an official slogan of "United for Baseball".
The re-activated Wei Chuan Dragons rejoined the major league 21 years after disbandment in 1999, marking the first time a CPBL season included more than four teams since the 2008 season. As CPBL Commissioner Wu Chih-yang termed out following the conclusion of the 2020 season, the general managers elected Vice President of the Legislative Yuan Tsai Chi-Chang as the new Commissioner.
The season started on March 13, with the opening game played, per tradition, by the prior season's championship series pair: the 2020 champion Uni-President Lions defeated CTBC Brothers at Tainan Municipal Baseball Stadium, 10–4. The season ended in late November, followed by a Taiwan Series rematch. The Brothers defeated the Lions in a four-game sweep to capture the 2021 championship.

## Game play

Seeing the 0.560~0.570 coefficient of restitution (COR) of the 2020 game balls created too much of an offense-leaning game, the General Managers decided on September 24, 2020, to reduce the COR of 2021 game balls to 0.550 and raise the stitch height from 5mm to 7mm. The league hoped that this would restore the balance between pitchers and hitters, and align with balls used by neighboring KBO and NPB leagues.
As COVID-19 pandemic still widespread around the world, the CDC and the League decided to retain restriction first implemented in the second half of 2020 season: the maximum attendance of the game was reduced to 78% of each stadium's seating capacity, but food and drink was allowed.
League-organized pre-season games started on February 26, 2021, and ended on March 10. The regular season opening game played on March 13 at Tainan Municipal Baseball Stadium, with last season's champions Uni-President Lions hosting their 2020 Taiwan Series opponent the CTBC Brothers. Game #2 followed the next day with the Lions hosting the Wei Chuan Dragons at Tainan, this was the first major league game played by the Dragons since their disbandment in 1999.
Game #21 played on March 26 with the Rakuten Monkeys hosting Uni-President Lions at Taoyuan International Baseball Stadium was suspended at the top of the 4th inning after one out due to poor visibility caused by dense fog. This was the first CPBL game to be suspended due to fog, and the second if included called games.
The first-half season schedule was published on February 10, with second-half pending the release of 2020 Summer Olympic Baseball Final Qualifier schedule. Following the finalization of the Final Olympic Baseball Qualifier schedule, which would be held between June 16 and 20 at Taichung Intercontinental Baseball Stadium, the league decided on April 19 to postpone games previously scheduled on and after June 8 to later dates. Due to a recent spike in domestically transmitted coronavirus cases, the league announced on May 19 that it would suspend the season as long as level-3 health alert was in effect across Taiwan. The league considered but decided against resuming games on June 29 without fans in attendance, despite no opposition by the Central Epidemic Command Center to the CPBL's plan. The CBPL stated on July 12 that play could resume the next day, as teams had agreed to a number of preventative measures. These measures included the prohibition of fans and cheerleaders in the stadium, and a requirement for the staffs of all teams to live and remain in hotels, whether at home on the road, unless a game was being played. As the COVID-19 pandemic became less severe, the league allowed a thousand fans to attend games on August 7 and 8. Starting on August 10, fans were permitted to attend games starting August 10, as stadiums were to be filled up to 25 percent capacity. Attendees were required to check in via a QR code, wear masks at all times, and submit to disinfection and body temperature checks at stadium entrances. Though cheerleaders were also permitted to return to the games, bans on musical instruments and food consumption remained in place at the time.

## Milestones

* Before the first game of the regular season for the Wei Chuan Dragons, the team invited 326 people to attempt 163 ceremonial first pitches. A new record for simultaneous ceremonial first pitches was set at 156 pitches, as Guinness World Records adjudicators required attempts to be thrown at the same time and caught cleanly.
* Tim Melville (Uni-President Lions) pitched a no-hitter against Wei Chuan Dragons on April 2, and set a league record of 142 pitches thrown in a no-hitter. This was the 10th regular season no-hitter in the league history, the 11th if included post season, fourth in the team history, and the first in Melville's professional career.
* Brock Dykxhoorn (Uni-President Lions) pitched a one-hit minimum batters faced game against Fubon Guardians on April 14. The only base-runner reached on a single in the third inning, but was erased on the next batter's ensuing double play, meaning Dykxhoorn faced only 27 batters.

Because the first half and second-half championships were won by different teams, the 2021 Taiwan Series, a best of seven series, was played. The first-half champions, the CTBC Brothers, faced the second-half champions, the Uni-President Lions, with the first game scheduled on November 27 and the seventh game on December 5. Games after the first four will only be played if necessary. The Brothers, by having a better yearly record, earned home field advantage, hosting games 1, 2, 6, and 7 at their home field, Taichung Intercontinental Baseball Stadium. The Lions hosted games 3 at Chengcing Lake Baseball Stadium, 4 and 5 at their home field, Tainan Municipal Baseball Stadium. The series will be a rematch of the 2020 Taiwan Series which Lions won four games to three en route to their 10th Taiwan Series victory and first since 2013.
