INGLEWOOD, Calif. - Ball Four led throughout Saturday's $150,000 Mervyn LeRoy Handicap at Hollywood Park to record his third career stakes win, and give the heavily favored Rail Trip the first loss of his career.

Ball Four ($34) set a reasonable pace of 24.38 and 47.94 seconds and held off a sustained threat from Rail Trip to win the Grade 2 race by 1 1/4 lengths. Ball Four ran 1 1/16 miles in 1:41.58.

Dakota Phone finished third in the field of six, 1 3/4 lengths behind Ball Four.

GRAND PRAIRIE, Texas - Mythical Power was a dominating 7 1/2-length winner of the Grade 3, $400,000 Lone Star Derby on Saturday, one start after finishing in front of future Kentucky Derby winner Mine That Bird in last month's Sunland Park Derby.

The Lone Star Derby was one of three stakes worth a cumulative $650,000 at Lone Star Park on Saturday. Valid Stripes, who also came out of the Sunland Derby, won the $125,000 colts division of the Texas Stallion Stakes, while the $125,000 fillies division went to City Tone.

ARLINGTON HEIGHTS, Ill. - Soft turf at Arlington: Snapphok likes that.

At 23-1, Snapphok was the longest shot among seven horses in the $53,900 Chester House Stakes on Saturday at Arlington, but he won fairly easily, slipping between horses after straightening for home and dashing clear to win by 1 3/4 lengths.

Snapphok scored a narrow allowance win over a soft Arlington course last summer, finishing fast behind a slow pace, just as he did Saturday.

"Obviously he does like it," said winning trainer Jim Gulick. "It worked out pretty well."

Stuck in Traffic ($11.50) closed from just off the pace en route to a handy victory in Saturday's $126,600 New Providence Stakes at Woodbine.

Stuck in Traffic, normally a front-runner, assumed a stalking position on the outside, as favored Drunken Love set wind-aided fractions of 21.87 seconds and 44.57 in the six-furlong dash.

Secretintelligence and Marie Soleil, a pair of 6-1 shots, captured the first two stakes of the season at Philadelphia Park on Saturday.

Secretintelligence ($14.40) prevailed by a neck over Movin' Out in the Lyman Handicap, while Marie Soleil beat defending champion Jet Away Jane by 1 3/4 lengths in the Foxy J.G. Stakes. The stakes for Pennsylvania-breds were each worth $75,000.

Acting Zippy, emerging as a leading sprinter in the Mid-Atlantic region, captured Saturday's $74,200 Decathlon Stakes, the opening-day feature at Monmouth Park. The Oceanport, N.J., track drew a crowd of 10,292 for its first of 94 days.

It was the second straight stakes win for Acting Zippy, a 4-year-old chestnut gelding trained and co-owned by William Bennett.

In his previous start, Acting Zippy pulled off a 24-1 stunner in the Vincent Moscarelli Memorial at Delaware Park. The Decathlon price was 5-2, but the outcome, and the trip, were identical.

ELMONT, N.Y. - Back on conventional dirt, Charitable Man was back to his winning ways Saturday, putting forth a dominant effort in the $200,000 Peter Pan Stakes, one that could make him a factor in the Belmont Stakes in four weeks.

La Chica Rica is back to defend her title Tuesday in the $75,000 Hancock County Handicap for fillies and mares at Mountaineer Casino Racetrack and Resort.

"I'm looking forward to running her," said trainer Crystal Pickett. "She looks good. She's training super."

The win last year was the middle victory in a five-race winning streak, a run that propelled the mare to an excellent season with earnings of $233,526.

One Smokin' Lady was all out to just last by a neck in the $100,000 Inaugaral on opening night at Presque Isle Downs on Friday. Jockey Frankie Pennington saved every inch of ground in the six-furlong event and took the lead in upper stretch. One Smokin' Lady, a 3-year-old daughter of Smoke Glacken, then gamely held off the late charge of Onearmedbandit. Ridden by Erick Rodriguez, Onearmedbandit was gaining on the outside in the field of six 3-year-old fillies. Southern Yankee set the early pace but faded in the stretch and finished third, three lengths behind the top two.

ETOBICOKE, Ontario - Trainer Josie Carroll may be suffering from an embarrassment of riches on the filly and mare front this season.

"I have a barnful of really nice fillies this year," said Carroll, just before entering Smart Surprise and Authenicat in Sunday's Grade 3, $150,000 Hendrie at 6 1/2 furlongs.

Serenading, who was entered in a 1 1/16-mile classified allowance race that failed to fill for two consecutive days before being scrapped, will be a going concern this year going long.
