The IPT’s North American 8-Ball Open is shaping up to be the Philippines 8-Ball Smackdown.

The Filipino contingent flew their flag high and often on Monday — the second day of the history-making, $2 million event — as six Pinoy shooters scored perfect 4-0 records in round-robin play: Efren Reyes, Alex Pagulayan, Francisco Bustamante, Marlon Manalo, Dennis Orcollo and Ronato Alcano.

Joining the ranks of the undefeated was Brit snooker and 9-ball superstar Allison Fisher, who steamed through a fairly soft bracket to qualify for the next round of play. However, she was one of only two women of the 15 female tour members to score a winning record, and one of only four to advance. The U.K.’s Sarah Ellerby had the other winning record, 3-1.

Top female pros making early exits Monday included Ireland’s Karen Corr, who went 1-3 in a particularly tough draw; the U.K.’s Kelly Fisher, 1-3; Helena Thornfeldt of Sweden, 0-4; and American Monica Webb, 0-4.

Play on Monday centered on the second set of 100 competitors in the 200-player field, divied up into 20 groups of five. The top three in each group advanced to today’s round, featuring the remaining 120 players, parsed into 20 groups of six.

The 80 eliminated players from the first round will settle for $2,000 each. The winner of the event will pocket a record $350,000.

Here’s a brief wrap-up of Monday’s highlights:

• One of the biggest surprises of the Open so far is the number of players who qualified for the event — those not among the 150 regular IPT tour members — who are posting undefeated records. These surprise contenders from Monday’s play include Dutchman Rico Diks; England’s Karl Boyes; and Anthony Ginn of Australia.

• Keith Bennett, a 27-year-old house pro at Breaktime Billiards in Wilmington, N.C., who made it into the Open as alternate after Hall-of-Famer Jim Rempe bowed out, posted a 4-0 record in the first-round on Monday.

• The four women to advance to Tuesday’s matches in the round-of-120 were Allison Fisher, 4-0; the U.K.’s Sarah Ellerby, 3-1; Hall-of-Famer Loree Jon Jones (U.S.), 2-2; and Austria’s Gerda Hofstatter, who managed to limp into the next round with a 1-3 record when her games-won percentage topped two other players in her group with the same record (Ed Kelly and Jim Weast, both of the U.S.; Hofstatter’s games-won percentage was in fact just 1 percent higher than Weast’s).

• Beyond the Filipinos, who were expected to do well, several favorites sent messages to the field that they were not to be underestimated. Also posting 4-0 records were well-regarded Americans Johnny Archer and Shannon Daulton, and Germany’s Oliver Ortmann.
