To say Corey Callahan had a good night at the office Tuesday at Dover Downs would be a gross understatement.

Callahan nabbed seven wins on the 15-race card, and it was a pacer named Nullity (1:56.1) that got the ball rolling for the productive reinsman in Race 2. He also lit the lamp with Devil May Care (1:54.3 – Race 6), Sweet Robbie (1:53.4 – Race 9), Shine N Shimmer (1:51.1 – Race 10), Shark Princess (1:53.4 – Race 11), Mach A Wish (1:54 – Race 12) and Robintheatm (2:00.1 – Race 15).

The seven-win performance lifted Callahan’s 2015 win total to 561 while his career total soared to 4,532. He’s racked up in excess of $8.6 million this season and more than $62 million to date.

The program also featured a set of $20,000 divisions of the Delaware Standardbred Breeders Fund for two-year-old trotting colts and geldings.

Chipoffthewall was a wire-to-wire winner in the opening division for driver Tony Morgan and trainer Syl King, Jr. The son of Master Lavec-Off The Wall led the field through fractions of :29, 1:01 and 1:31 before using a :28.2 kicker to win by 6-1/2 lengths over Mondello. Politicized rounded out the top three finishers.

Sent off as the 1-9 favourite, Chipoffthewall won for the fourth time this season for owner Glen Zimmerman of New Holland, PA. The rookie has banked more than $40,000 in his career.

Popcorn Machine turned a second-over trip into a comfortable score in the second division. Jim Morand got away fourth with the gelding while Bosston Malibu fired to the top and chopped out panels of :28.4, 1:00 and 1:32. Chrome Master made a first-over bid in the backstretch and Popcorn Machine was able to slip out and catch that foe’s cover. Morand flipped off cover late and his charge only needed a :31.3 closing panel to win by 1-1/2 lengths over Bosston Malibu in 2:04.1. Even-money favourite Seafood Scrappy recovered from an early miscue to salvage a third-place finish.

Scott Warnick trains the son of Giant Hit-Blackdenimtrousers for Deborah Warnick of Locust Hill, VA. It was a maiden-breaking score for the youngster who upped his lifetime earnings to $22,663 with the win.
