Young outfielder Mike Trout might be the No. 1 prospect in baseball, according to some rankings. But one of his veteran teammates had his number Monday — and shared it with everyone.

After the top of the first inning of Monday’s game between the Angels and A’s, Trout’s phone number was splashed all over the scoreboard at Tempe Diablo Stadium with an invitation.

“Fans call Angels’ Mike Trout directly with your baseball questions,” said the message which was repeated several times throughout the game.

The 19-year-old Trout apparently offended the sensibilities of some of his more established spring teammates during the daily team meeting Monday.The morning meetings under manager Mike Scioscia feature team-bonding exercises with the youngest players forced to make presentations in front of the group. Most mornings, the laughter can be heard outside the closed doors.

It wasn’t Trout’s turn to make a presentation Monday morning but he must have crossed the unwritten ‘speak-only-when-spoken-to’ line.

Retribution was swift and public.

“I deserved it so I knew it was coming,” Trout said after the game, clearly embarrassed by reporters asking about the prank. “It’s alright.”

Trout tried to shrug it off in front of reporters, saying he only had a couple messages on his phone. But right-hander Joel Pineiro spoke with us after his two innings of work and said Trout’s phone was “blowing up” in his locker.

“He’s ‘The One,’ the ‘Golden Child,’ the top prospect in baseball, right?” Pineiro said, tongue firmly in cheek. “So he just wants to get to know the fans.”

Trout’s teammates tried to protect the identity of the veteran he had crossed.

“You know I’m not saying,” Angels outfielder Torii Hunter said. “I’m not the guy who ordered the hit.”

That guy was nowhere to be found after the game — right-hander Jered Weaver.

“Weave got him good,” Angels outfielder Peter Bourjos said, Trout admonishing from across the room not to give away too much — “Outfielders stick together,” Trout pleaded.

“I told him (Weaver), ‘Why’d you do it today?” Bourjos said, referring to the small crowd in the stadium (2,822). “Do it when we’re playing the Cubs.”

It was pointed out to Trout that it would be a shame for that phone number to find its way into print or onto the world-wide web.

“Go ahead. Put it out there,” he said. “It’s going to be the wrong number.”
