Gygistar got sick after posting a gate-to-wire victory in the Dwyer on July 7th at Belmont Park and has missed a work.
"He'd had a little bug. He's doing real well," Hennig said. "He's galloping now.
"His hair coat has got a little dull on me. I'm going to gallop him in the next couple of days and make a decision on working him this weekend. If he worked and he worked well, I'll make a decision then on where to go and what to do."
Hennig said Gygistar would miss the Jim Dandy, the prep for the $1 million Travers, if the work is postponed.
"Right now I'd say it's probably about a 25 percent chance of running," Hennig said.
If Gygistar doesn not make the Jim Dandy, Hennig said he will be pointed for the seven-furlong King's Bishop on Aug. 24.
Hennig's quartet of stakes-winning fillies are all headed to Saratoga stakes.
With Ability will be the first to go to the gate Sunday in the Go For Wand. With Ability won the Next Move at Aqueduct on March 29, and the SixtySails at Sportsmen's Park on April 28, and finished second to Spain in the Fleur de Lis on June 15.
Gold Mover, who handed champion Xtra Heat a rare defeat in the Princess Rooney Handicap at Calder on June 13, may run in the Honorable Miss on Aug. 2.
"I'm going to breeze her as early as Friday and then make a decision for sure," Hennig said.
"It would be back in three weeks off the race at Calder, but she seems to be really fresh and doing well. It doesn't seem like that trip knocked her out. We flew in and out of there so quick that I don't think the heat really had a chance to get toher. We got her up here right away so she still seems prettyfresh."
Hempstead winner Raging Fever is scheduled to breeze again this weekend as she prepares for the Ballerina on Aug. 25. Gold Fever may also run in the Ballerina.
Hennig said that Delaware Handicap winner Summer Colony has come out of the race OK and is likely to run next in the Personal Ensign on Aug. 23.Spa Notes: Kimmel Off to Good Start; Booklet May Run at Meet
The 134th season at Saratoga opened Wednesday under sunny skies. Long lines of fans were queued up outside the track before the gates opened at 11 a.m.
Heavy rain on Tuesday left the main track muddy and the turf course yielding. The first race of the meet was taken off the grass and run on the main track. The main track was upgraded to good.
Trainer John Kimmel got off to a good start, winning the first with Hydrogen ($6.50) and the third with 2-year-old first-times Silver Squire, who paid $63 to win.
Trainer John Ward said that multiple stakes winner Booklet may return to the races for the first time since the Preakness later in the meet. The Notebook colt arrived in Saratoga Wednesday.
"The spring racing just took a lot out of an immature horse," Ward said. "There's nothing seriously wrong with him, but he's just kind of coming out of that 'Road to the Derby' syndrome. Three hard races at Gulfstream and a race at Keeneland is tough to ask of any young horse. He's been back in training. He hasn't quite satisfied me forwhat he's looked like. It's immaturity. We've done all the different x-rays and scans and all that stuff. It's just immaturity.
"So he will visit the Spa and visit the Oklahoma training track, which is good and soft, and he's visit the Oklahoma grass some, too, because I think he might could possibly have a future on the turf. He would be one steaming miler."
