TENNIS-US OPEN

Zverev and Bencic advance to quarterfinals

NEW YORK (AP) — Alexander Zverev is into the U.S. Open quarterfinals with his 15th straight victory. The No. 4 seed from Germany beat 13th-seeded Jannik Sinner 6-4, 6-4, 7-6 (7).

Zverev started his winning streak at the Olympics, where he beat top-ranked Novak Djokovic in the semifinals en route to the gold medal.

Djokovic is in action later Monday.

Meanwhile, Belinda Bencic is back into the quarterfinals of the U.S. Open. The Olympic gold medalist from Switzerland beat Iga Swiatek 7-6 (12), 6-3 to make the last eight in Flushing Meadows for the third time.

The 11th-seeded Bencic pulled out the lengthy first-set tiebreaker, then took the second set in 43 minutes — only about 20 more than the tiebreaker lasted.

Bencic was a semifinalist at the U.S. Open in 2019, the last time she played. She also reached the quarterfinals in her debut in 2014.

Two Dolphins on COVID list

MIAMI GARDENS, Fla. (AP) — The Miami Dolphins have placed presumed starting left tackle Austin Jackson and backup tight end Adam Shaheen on the COVID-19 reserve list. It calls into doubt their availability for the team’s opener at New England. Cornerback Jamal Perry was elevated to the active roster as a COVID-19 replacement. This is the second time that Shaheen has been on the list. He also missed some time last month because of contact tracing and said he would not be vaccinated.

Elsewhere in the NFL:

— The Chiefs remained without All-Pro safety Tyrann Mathieu after his positive test for COVID-19 as the two-time defending AFC champions began preparing Monday for their season opener against Cleveland. Chiefs coach Andy Reid said that Mathieu remained in the league’s protocol. He was vaccinated, so that means Mathieu has yet to return two negative tests taken 24 hours apart.

— Panthers starting right guard John Miller has been placed on the COVID-19 reserve list and will miss Carolina’s season opener on Sunday against the New York Jets. Panthers coach Matt Rhule said Miller will be out 10 days, which according to league rules would indicate that he was an unvaccinated player who tested positive. Rhule said Dennis Daley will start in his place. A six-year NFL veteran, Miller started 14 games last season for the Panthers.

— New York Jets wide receiver Jamison Crowder is recovering from symptoms of COVID-19 and his status for the opening game at Carolina remains uncertain. Coach Robert Saleh said Monday that Crowder is vaccinated against the virus, but the receiver’s availability for the season opener will depend on how he feels and tests.

— San Francisco 49ers rookie quarterback Trey Lance showed signs of progress in returning from a finger injury but there are still questions about whether he will be able to play in the season opener. Lance no longer needed a splint on the index finger on his throwing hand after suffering a small chip fracture in the exhibition finale on Aug. 29. But during the open portion of practice for reporters, Lance didn’t make any throws.

— Curtis Samuel took part in Washington’s Labor Day practice and looks like a candidate to play in the season opener against the Los Angeles Chargers after missing training camp. Samuel spent time on the NFL’s COVID-19 list and has been hampered by a groin injury since offseason workouts. Coach Ron Rivera says Samuel was a limited participant and the staff does not believe the receiver needs to take part in a full practice to play Sunday.
