The Ravens have exercised the fifth-year option on starting left tackle Ronnie Stanley, a league source tells Field Yates of ESPN.com (on Twitter). With that, Stanley is now under contract through the 2020 season.

There was little doubt that the Ravens would pick up the fifth-year option on the 2016 first-round pick. Stanley has been a starter for the Ravens in all three of his NFL seasons and, last year, he graded out as the No. 17 ranked tackle in the league, according to Pro Football Focus.
The additional year will cost the Ravens $13MM in 2020 after his initial four-year deal wraps up. It’s not chump change, but it’s well worth it for the Ravens to lock down one of the best young tackles in the NFL.
The Ravens had until May 3 to make the call, but they didn’t need to take it down to the wire. Stanley’s $13MM sum will be guaranteed for injury only, so the club can easily get out of the deal if there’s an unexpected regression in his performance.
