A man was killed near the San Francisco Giants home ballpark on Wednesday from a fatal stabbing. The incident left 24-year-old Jonathan Denver dead, following the Giants 6-4 victory over the Los Angeles Dodgers.

Police Chief Greg Suhr told the San Francisco Chronicle that Denver was a Dodgers fan and was wearing Dodgers apparel. Authorities have arrested two people in connection with the murder, which took place shortly after 11:30 p.m. PT. This incident occurred a few blocks away from AT&T Park, according to Giants' spokeswoman Staci Slaughter.

It’s unknown if the two people arrested were Giants fans or what led to the stabbing. All police have said is Denver was killed during a fight between two groups of men.

The Giants and Dodgers are fierce rivals and there has been a recent history of violence between the two fan bases. After the two teams played in L.A.’s home opener in 2011, a Giants fan was beaten by two Dodgers fans in the parking lot. The attack left the victim, Bryan Stow, with brain damage.

There have been several incidents at San Francisco sporting events in the past few years. Two men were shot in the Candlestick Park parking lot after a 2011 preseason game between the San Francisco 49ers and the Oakland Raiders. This past Sunday, a fan suffered a concussion, and a broken arm and nose in an attack during the 49ers' loss to the Indianapolis Colts at Candlestick.
