La Russa during Sunday's television broadcast that home plate umpire Jerry Meals had "two different strike zones." St. Louis, which trailed 4-0, rallied to win the game 5-4 and evened the best-of-five series at 1-1.
On Tuesday, La Russa said he had let his emotions get the best of him and had no beef with being fined.
"I'm embarrassed that I crossed the line," La Russa said. "I know what the line is. I got upset and I crossed the line. If I get a chance, I will apologize to Jerry. Like I said, I've never had any problems with him. He's a pro. He has my utmost respect. We were competing, and I got upset and crossed the line."
