PALM BEACH, Fla. — Baseball owners are again looking at possible rule changes to speed up their game.

Rob Manfred has pushed for faster games since he became commissioner two years ago. But the average game last year took exactly 3 hours, a 4-minute increase over 2015.

The new collective bargaining agreement extends labor peace to 26 years through 2021 and addresses such issues as smokeless tobacco and World Series home field advantage. Rule changes concerning pace of play weren’t included, but owners discussed them during two days of meetings that concluded Friday.

Management would like to tighten restrictions on trips to the mound and introduce a pitch clock, which has been used in Triple-A and Double-A the past two seasons. Players have resisted such changes.

TWINS: Minnesota designated slugger Byung Ho Park for assignment following a disappointing major league debut in 2016.

The Twins made the potentially expensive move on Friday so they could make room on the 40-man roster for right-handed reliever Matt Belisle, who finalized a $2.05 million, one-year contract with the Twins after posting a career-best 1.76 ERA last season for Washington.

The 30-year-old Park batted .191 with 12 home runs and 24 RBI in 62 games last season.

ROYALS: Closer Kelvin Herrera agreed to a $5,325,000, one-year contract, avoiding arbitration with one of the top relievers in baseball.

Herrera can also earn $50,000 for making the All-Star Game, which he has done the past two seasons.

The 27-year-old right-hander is assuming the closer job after the Royals traded Wade Davis to the Chicago Cubs this offseason.

PHILLIES: Utilityman Chris Coghlan agreed to a minor league contract and the team settled its salary arbitration case with second baseman Cesar Hernandez by reaching a $2.55 million, one-year deal.

Coghlan hit .252 with one homer and 16 RBI in 103 at-bats for the World Series champion Chicago Cubs last season and was 0 for 7 in the postseason.

Philadelphia had offered Hernandez a raise from $525,000 to $2 million, and the infielder asked for $2.8 million.

METS: Infielder Wilmer Flores became the first New York Mets player to go to salary arbitration since Oliver Perez in 2008. Flores asked for a $2.2 million salary, and the Mets argued for $1.8 million during Friday’s hearing. A decision is expected Saturday.
