Monmouth Park has canceled its Saturday races due to extreme temperatures. Monmouth also canceled its Friday card due to the heat wave.\r\nOther East Coast tracks to cancel Saturday are Delaware Park, Parx Racing, Suffolk Downs, and Penn National.\r\nSaturday&rsquo;s Monmouth card will be rescheduled for sometime later in the season. The meet runs through Sunday, Nov. 5.\r\n&ldquo;Unfortunately the heat hasn&rsquo;t broken,&rdquo; said Robert Kulina, vice president and general manager of Monmouth Park. &ldquo;While we remained hopeful that we would be able to continue racing today, the extreme heat simply made that impossible.&rdquo;\r\nLive racing is scheduled to resume at Monmouth Park on Sunday. The facility remained open for simulcasting Saturday.
