Leinart has means of support

Attention, athletes:

The California Department of Child Support Services website has a handy-dandy calculator where you can input your income and other financial and personal details and receive an estimate of how much child support might be ordered by a judge.

Our initial guess: The more than $30,000 a month celebrity gossip site TMZ.com reported USC basketball player Brynn Cameron is seeking from former Trojans quarterback Matt Leinart for their son is not as outrageous as it might seem, based on Leinart’s contract with the Arizona Cardinals potentially being worth close to $51 million over six years, plus endorsement income.

Child support determinations in California aren’t based on reasonable living expenses, and there is no stated maximum.

“It’s based on income, the amount of visitation, and a whole host of complicated factors,” such as whether the non-custodial parent is supporting other children, said Maria Caudill, assistant director for communications and public affairs for the Department of Child Support Services.

“But when the calculations are completed, it’s still up to the court and the individuals involved as to what the final amount will be,” Caudill said.

Trivia time

Who pitched the first no-hitter in Dodger Stadium history?

The zoom on ‘shrooms

Horse trainers are always looking for something -- preferably legal -- to keep their equine athletes healthy, happy and fast.

Here’s a new one: mushrooms.

Among the trainers feeding some of their horses mushroom products are Carl Nafzger, trainer of Kentucky Derby winner Street Sense, and John Shirreffs, trainer of Tiago, the California horse that finished third in the Belmont.

“It’s totally legal,” Shirreffs said. “It’s just a health-food product. It’s not a drug, not a stimulant. This is not psychedelic mushrooms.”

The product Shirreffs uses, Mushroom Matrix, is a powder produced by Golden Gourmet Mushrooms of San Marcos.

“I know when you go to a health-food store, there are different types of mushrooms,” Shirreffs said. “They’re good for the immune system, the horses like it and it stimulates their appetite. Anything you can do for a horse’s digestion is good.”

Sometimes it gets complicated, though.

Dr. Rick Arthur, equine medical director for the California Horse Racing Board, said the makers of Mushroom Matrix checked with him about marketing their product for racehorses, and “it should not be a problem.”

“But you have to be very concerned about quality controls,” Arthur said. “Mushrooms are usually raised on horse manure.

“You have to hope the horse they got that manure from didn’t eat anything that tested positive.”

Oxymoron alert

The state racing board recently took action to allow jockeys to use a “kinder whip.”

The tips of the new whips have “softer, padded leather that is narrower and rounder without any hard edges.”

This is one more time we wish we could get a comment from a horse.

Trivia answer

The first no-hitter by a Dodger in the stadium was by Sandy Koufax on June 30, 1962, in a 5-0 victory over the New York Mets.

And finally

Golden State Warriors guard Baron Davis, asked on “Best Damn Sports Show Period” if he’ll scrutinize referees more closely because of allegations an NBA ref bet on games he officiated:

“When we lose, I blame the referees anyway.”
