There were no violent incidents during or after Thursday night's game, which was a 9-5 loss for the Los Angeles Dodgers to the St. Louis Cardinals.
With a command post set up in the Dodger Stadium parking lot, the LAPD doubled the usual amount of officers who patrol the game.
"Right when you pull up, you know, when you see 20 cops and cars on the road coming in, it gives you a sense of security, especially after what's happened here, which is just atrocious," said fan Kevin Scott.
The amped-up security comes in the wake of the savage beating two weeks ago of San Franciso Giants fan Bryan Stow, who remains in a medically induced coma.
Some fans thought the show of force was long overdue.
"It would have been nicer to see them here on opening day and not so much on these games. These games are more family," said Rosemary Miranda.
There's no word on the cost of the additional security, but the Dodgers will pick up the expense.
Meanwhile, the LAPD said one of the two suspects has a mole on his left cheek and possibly tattoos on his neck.
Anyone with information related to the attack was urged to call the Los Angeles Police Department at (877) LAPD-24-7 (877-527-3247).
