"Looking back on it, I probably should have run out there 10 seconds faster," Black said Friday prior to the Padres series opener against the Marlins.
"When you issue a challenge, it shouldn't take as long as it took me to pop out of the dugout. It's the same amount of time, but they [umpires] would rather have me on the field and not the dugout."
Black tried to challenge a call in the first inning on Yasiel Puig's sacrifice bunt. Black felt starting pitcher Tyson Ross' throw to first baseman Yonder Alonso didn't pull him off the bag, as first-base umpire Sean Barber indicated. Puig was given a sacrifice and Ross an error for the throw.
Black emerged from the dugout and indicated to Barber that he was going to challenge the call. But the next batter, Hanley Ramirez, was in the batter's box and Ross had the ball on the mound. Black said the umpires told him that the challenge wouldn't be allowed due to "time constraints" and that "he took too long" to issue the challenge.
"They don't want another play to start to develop," Black said. "We as managers have to go out quicker."
Black said he asked what the time constraints were, but he wasn't given an answer.
"I don't have a timer," Black said at the time.
