The new digital timers tracking between-inning breaks and pitching changes did not appear to be noticed much Monday, the first full day of Major League Baseball's effort to speed the pace of games.

"I've never had a problem with it, so I just went and did my thing," Baltimore pitcher Chris Tillman said following a 6-2 victory at Tampa Bay.

New regulations require hitters to keep a foot in the batter's box — with seven exceptions. The clock times inning breaks and pitching changes at 2 minutes, 25 seconds for locally televised games and 2:45 for nationally televised games. Pitchers must throw their last warmup pitches before 30 seconds remain, with exceptions if the pitcher or catcher is on base when the previous half-inning ends.

"I didn't pay any notion," Yankees catcher Brian McCann said following a 6-1 loss to Toronto.
