Major League Baseball's move to cut two seconds off the pitch clock with runners on base is coming too soon, according to Tony Clark.

The clock is shortening this season to 18 seconds from 20 with men on base and will stay at 15 seconds with no one on.

"That's a conversation that should have warranted a much longer dialogue than what we had," Clark, the head of the MLBPA, said. "We voiced those concerns, players voiced those concerns, and yet, the push through of the change to the pitch clock still happened."

MLB introduced a new rules package last season -- including a pitch clock and bigger bases -- that cut average game times by 24 minutes to 2 hours, 40 minutes, the quickest games have been played since 1984.
