Driver Doug McNair and trainer Joe Pereira teamed up to kick off the fifth annual Slots Cup Series with a pair of popular winners on Tuesday at Western Fair Raceway.

Making their London debuts, Mach Three sophomore pacers Machal Angelo and Addwater won the first two $15,000 divisions of the opening leg for the duo while four-year-old Royal Mattjesty gelding Royal Outlook captured the other split for driver Trevor Henry and conditioner Dan Creighton.

Post three starter Machal Angelo ($3.20) took control of the six-horse field in the opener and posted a :27.2 first quarter before being confronted by second choice Talldarknhandsome and Jason Brewer. The first over attacker edged out in front through middle panels of :56.4 and 1:25.1 and nearly cleared, but Machal Angelo put him away into the stretch and held off the pocket-pulling Pisti and Henry for the 1:56.4 half-length victory. Distinctiv Richie, with Ryan Holliday aboard, rallied off second over cover to show.

Addwater ($4.20) was a gate-to-wire winner in the seven-horse second split. The inside starter established the lead off the gate and cruised through fractions of :27.4, :57.4, and 1:26.4 en route to a 1:55.4 score. Longshot Rustlin Cam and Robert Sparling Jr. followed over five lengths behind off a pocket trip while Jettison and Henry came in third.

Both McNair-Pereira winners are owned by The Merks Stable of New York.

Later on the card, Royal Outlook ($2.70) advanced first over from fourth after the :27-second opening quarter and engaged in a back and forth battle for the lead with Life Signature, driven by McNair, through middle panels of :56 and 1:24 before wearing him down and going on to score by two lengths in 1:54.1. Life Signature held second while the Bruce Richardson-driven Windsong Harley finished third in the seven-horse field. Danterra Racing Stable of Strathroy, Ont. owns the London regular, who has yet to miss the board in 15 starts this year (10 wins).
