San Francisco 49ers defensive lineman Arik Armstead continues his breakout season.

The former Oregon Ducks’ star posted a sack for the second consecutive game during the 49ers’ 9-0 win over Washington on Sunday. Armstead sacked Washington quarterback Case Keenum for a 9-yard loss on a third-and-5 play in the third quarter. Watch

Armstead’s sack increased his total to 3.5 sacks on the season, marking a new career-high.

Armstead’s sack and the 49ers’ stop was important. Washington had intercepted a Jimmy Garoppolo pass on the previous series. Armstead’s sack and stop snuffed out any possible momentum for Washington.

Armstead has already reached a career-high in sacks and he’s on track to set a career-high for total tackles this year. Armstead, the 49ers’ first-round pick (No. 17) in the 2015 NFL draft, is in the final year of his contract. If he continues to play at a high level, he’s going to get a big payday, whether it’s from the 49ers or somewhere else.
