NEW YORK — Baseball Commissioner Rob Manfred and players’ association head Tony Clark met Tuesday, five days after the union rejected Major League Baseball’s proposal to institute pitch clocks and limits on mound visits.

Management has the right to implement the rules changes it proposed last year. Under baseball’s labor contract, management can change on-field rules on its own with one season of advance notice.

MLB does not intend to make any decision before its next owners’ meetings, scheduled for next week in Beverly Hills, California. Big league spring training games start Feb. 23 and the season opens March 29.

“We discussed a wide range of topics,” Clark said in an email. “I will now be discussing each of those topics with our player leadership.”

Manfred did not respond to an email seeking comment.

Nine-inning games averaged a record 3 hours, 5 minutes during the 2017 regular season and 3:29 during the postseason, and the length of games has concerned club owners and executives in an age where they compete for consumers with more entertainment choices and shorter attention spans.

Under the proposal MLB can implement, there would be a 30-second clock between batters and a 20-second clock between pitches, according to details obtained by the AP.

A hitter would be required to be in the batter’s box with at least 5 seconds left on the timer. The clock would start when the pitcher has the ball on the mound, except for the first pitch of an at-bat, when it would start at the end of the previous play.
