I thought it at the time (that Valentin cost the Reds a double by coasting out of the box in the 3rd inning) but apparently Baker isn't going to watch these things without response...
From Fay's Blog:
Of course, it's REAL change when it either doesn't happen again from anyone or if Dusty will deal with Griffey, Dunn et al in a similar manner...Javy Valentin thought the ball he hit in the third might be out. He broke out of the box slowly. The ball hit the base of the fence in right. He ended up with 330-foot single.
Could it have been a double?
"Maybe," Valentin said. "If I run right away, I got an opportunity."
"It's been addressed," Dusty Baker said.
"I apologized," Valentin said. "It's not going to happen again."
