Cooper Flagg dominates with 29 points, Dallas adds to winless Miami's misery with 113-109 victory

MIAMI (AP) — Cooper Flagg had 29 points and 11 assists, plus blocked a shot that would have given Miami the lead in the final moments, and the Dallas Mavericks sent the reeling Heat to 0-4 with a 113-109 win on Monday night.

PJ Washington added 20 points, Kyrie Irving scored 18 and Walter Clayton Jr. had 15 for Dallas. Flagg had 12 of his points in the fourth, and his block of a 3-point try by Andrew Wiggins with 31 seconds left preserved a two-point Mavs lead.

The 19-year-old Flagg also had six rebounds, four steals and two blocks. Before Monday, the youngest player to have that many points, assists, rebounds, steals and blocks in game — since blocks started being charted — was 22-year-old Chris Webber in 1995.

Giannis Antetokounmpo had his first triple-double since joining the Heat, finishing with 29 points, 15 rebounds and 11 assists. Davion Mitchell scored 21 for Miami.

The Heat are 0-4 for the fifth time in team history, the first since 2008-09.

Miami started slowly, getting down 19-11 midway through the opening quarter — then outscoring Dallas 37-17 over the next 12 minutes to take a 12-point lead, its biggest so far this season.

It didn't last.

Dallas was up 53-52 at the half. The back-and-forth continued in the third, with Miami going up 10 not long after halftime but settling for an 84-83 lead going into the final 12 minutes.

Dallas took the lead back midway through the fourth and kept it, on a night where Miami missed 11 of 25 free throws.

It was the first meeting between first-year Dallas coach Dusty May and Miami coach Erik Spoelstra. May coached nearby Florida Atlantic to the 2023 Final Four and his son, Jack, worked in Miami's video room before joining his father's Dallas staff.

“He’s a heck of a coach," Spoelstra said of May, who led Michigan to the 2026 NCAA title. “There's no doubt about it.”

Mavericks: Host Oklahoma City on Wednesday.

ALBUQUERQUE (AP) — A major hospital network in New Mexico raced to fix a cybersecurity issue on Monday that forced it to send ambulances to other hospitals and left the state without an emergency department capable of treating the most serious injuries.

The University of New Mexico Health System told people not to show up at its main hospital in Albuquerque and canceled appointments at its more than 30 clinics. It said it was working to resolve the issue, the extent and nature of which was not immediately clear.

The hospital network conducts about 900,000 outpatient visits and receives 100,000 emergency room visits each year, according to its website. It operates the state’s only Level 1 trauma center.

Presbyterian Healthcare Services and Lovelace Health System, two other major healthcare providers in New Mexico, said they were coordinating with the UNM Health System, including taking additional patients.

The UNM Health System said in a statement that its hospitals and clinics began resuming operations in phases later in the day.

Multiple UNM Health System employees said they heard messages across their computers while working late Monday morning that claimed to have stolen student and employee data and patient information.

A spokesperson for the health system wouldn't comment, saying that the incident remains an active law enforcement investigation. FBI spokesperson Margot Cravens in Albuquerque said the agency was “assisting our partner” but declined further comment.

The Associated Press left emails and phone messages seeking comment from the Bernalillo County Sheriff’s Office and the Albuquerque Police Department.

The incident comes amid growing concern about the security of digital systems that underpin essential services, from banking to medical care.

Incidents affecting hospitals, including demands for ransom, have been going on for a decade, said Josephine Wolff, a professor of cybersecurity policy at Tufts University.

Breaching a system to play a message on computers is pretty unusual, Wolff said. Monday's incident, she said, shows "how much work we still have to do to get better at defending ourselves.”

On Monday afternoon, at the main entrance to its Albuquerque hospital, employees in turquoise staff shirts sat on chairs that blocked the waiting room and told patients their appointments might be canceled.

At a medical center in the Albuquerque suburb of Rio Rancho, two security guards at the entrance told patients arriving for appointments to reschedule.

UNM's Health Sciences Center, the state's largest academic medical center, canceled classes Monday and Tuesday. Employees in its hospital and medical group were expected back at work Tuesday.
