SAN FRANCISCO (KTLA) -- Giants' pitcher Tim Lincecum donated $25,000 Thursday to the fund for the Giants' fan that was brutally beaten at the Dodgers' home opener in Los Angeles.

The reward for the suspects who attacked Stow now stands at $175,000, after longtime radio host Tom Leykis pledged to kick in $50,000.

Lincecum's donation adds to the $50,000 from Leykis, $25,000 from the Dodgers, $50,000 from the L.A. County Board of Supervisors, $10,000 from the Giants and $5,000 from Stow's employer, American Medical Response.

Bryan Stow, a 42-year-old father of two and paramedic, remains hospitalized in critical condition in a drug induced coma at Los Angeles County-USC Medical Center.

"This was a senseless act of violence and I wanted to help out Mr. Stow and his family," Lincecum said in a statement released Thursday. "It is also close to me because not only is Mr. Stow a Giants fan, but I have family and friends who are firefighters, police officers, and paramedics, and this honors their service to the community."

In recent weeks, Los Angeles police officers added dozens of motorcycle, foot and vehicle patrols in and around Elysian Park in an effort to make the stadium safer.

"We have one rule: if you're threatening, if you're making comments that would lead to violence, you will be ejected," LAPD Chief Charlie Beck said hours before the 7 p.m. game.

Fans have also been barred from tailgating, and extra lighting has been added as a security measure.

The LAPD ticketed at least 46 people Thursday night, most of them for alcohol-related offenses, but no arrests were made. There were also no reports of violence.

Stow suffered a severe skull fracture and bruising to his frontal lobe.

Doctors had to remove a portion of Stow's skull to help reduce severe brain swelling. They say it's possible he sustained lasting brain damage.

On Wednesday, the team has announced its first big change to improve safety.

Half-price beer will no longer be sold during baseball games as part of a six-game "Throwback" promotion beginning April 21, the Dodgers said Wednesday.

The team will still dress in 1940s uniforms, will continue to include half-price food and soft drinks.

Dodgers owner Frank McCourt also agreed to create a computer mapping and crime tracking system for the stadium similar to the one the LAPD uses to monitor crime patterns and hotspots throughout Los Angeles.

LAPD Chief Charlie Beck has vowed to double police presence at games.

McCourt has agreed to pay for an increase in the number of LAPD officers patrolling in the stadium and the parking lots during and after games.

"You are going to see a sea of blue. And it's not going to be Dodger blue. It's going to be LAPD blue," Beck said.

Undercover police officers will be on hand as well, according to Beck.
