Here's my race-by-race rundown of Saturday's pick four at Betfair Hollywood Park on June 30, 2012. I'm building my wager with TicketMaker, found exclusively on DRF.com, with a $100 budget and $0.50 incremental bets.

LOUISVILLE, Ky. – Short fields going two turns often translates to a race with a slow pace. But in the case of the Grade 2 Firecracker Handicap on closing night at Churchill Downs, that doesn’t necessarily look like the case.

Two of the six older horses in the $150,000 Firecracker, which anchors the final program of the 38-day spring meet Sunday, have speed aplenty. So the prospect of an honest pace gives trainer Charlie Lopresti hope that the stretch-running Turallure, the solid favorite, will rebound from a disappointing last start and post his first triumph of the year.

ELMONT, N.Y. – After C C’s Pal earned her first graded stakes victory in the Grade 2 Vagrancy Handicap last month, trainer Richard Dutrow Jr. had a flexible plan to get the 5-year-old mare another one.

“We’ll just wing it, see where the good fillies are going, and try to duck them until we have to hit them,” he said.

Account wagering on Golden Gate Fields races increased 11.1 percent during its spring-summer meeting, which ended June 17 with a decline of 2.6 percent in average daily all-sources handle, according to figures provided by the track.

Total handle for the 101-day meet was down less than 1 percent compared to last year’s meeting, which ran for 99 days.

Bettors wagered $2,931,078 per day on live and simulcast Golden Gate races, compared to $3,009,827 last year. Average daily ontrack handle declined 8.7 percent from last year.

Ruby’s Big Band, who successfully invaded Assiniboia Downs for last year’s Canada Day, will be looking for a repeat in Sunday’s renewal of the one-mile feature for fillies and mares.

The Canada Day, which offers a purse of $30,000, will go as the eighth of nine races on a program that begins at 1:15 p.m.

Ruby’s Big Band, a Texas-bred 5-year-old owned by Terry Propps and trained by Charlie Smith, has won 13 of her 39 career starts and compiled a record of 7-3-2 from her 13 Winnipeg appearances.

ALTOONA, Iowa -- Six fillies will tackle the 1 1/16-mile distance in the Grade 3, $200,000 Iowa Oaks and it’s difficult to separate the top three who will vie for favoritism. Kentucky shippers Ice Cream Silence and Uptown Bertie, along with local sensation Tapajo, all carry excellent form into the Oaks.

Ice Cream Silence has won three in a row, including Churchill’s $68,000 Optimistic Gal by five lengths, an effort which impressed her opposition.

VANCOUVER, British Columbia – Management at Hastings is expecting a large crowd to show up on Monday to watch Mario Gutierrez ride St Liams Halo in the $50,000 Lieutenant Governors for 3-year-olds and up and Devil in Disguise in the $50,000 Chris Loseth for 3-year-olds.

Gutierrez had been one of the top riders at Hastings since he arrived here in 2006. He became a huge celebrity in Vancouver after he made a name for himself across North America by winning the Kentucky Derby and Preakness aboard I’ll Have Another.

AUBURN, Wash. – How fast is Polish Dollar? That will be the key question facing handicappers when they evaluate Saturday’s feature race at Emerald Downs. The eighth event on a nine-race program that begins at 2 p.m. Pacific, the feature – a first-level allowance at 6 1/2 furlongs – attracted five runners, and Polish Dollar is the perplexing wild card.

ELMONT, N.Y. – With a list of past winners that includes Man o’ War, Whirlaway, Assault, Damascus, and Holy Bull, it’s safe to say Saturday’s 95th running of the Dwyer Stakes at Belmont Park didn’t attract a comparatively strong group of 3-year-olds.

Not even close. Collectively, the field of seven has been beaten 76 lengths in six graded stakes attempts, not counting Guyana Star Dweej, who was eased in the Belmont Stakes.

The Dwyer, a Grade 2 worth $200,000 there for the taking, is the 10th of 11 races. Post time is 5:38 p.m. Eastern.

In anticipation of a heat wave approaching the East Coast, Delaware Park has canceled its live racing card scheduled for Saturday.

The National Weather Service had predicted temperatures above 99 degrees with a heat index of 108 for the Wilmington area.

“Racing in such weather would potentially place the health of the horses and riders at risk,” said Dr. John T. Peters, chief commission veterinarian for the Delaware Thoroughbred Racing Commission.
