Keaton Mitchell didn’t waste words. “22.4,” he wrote on X, followed by a yawning emoji.

It was a month ago Friday that the Ravens’ speedy running back reached that miles per hour number during a workout inside the field house at the team’s training facility in Owings Mills.

Through the first two weeks of practices on grass during organized team activities, he has looked the part, too, turning corners and burning angles of would-be tacklers.

Just how much better is the 23-year-old former undrafted free agent out of East Carolina 18 months removed from a devastating knee injury that he suffered in December 2023? His top speed shortly after he signed with Baltimore two years ago, he said, was 22.2 mph, so the answer is he’s even faster.

“He looks good,” coach John Harbaugh said Friday. “He looks way better than he did at the end of last season just as far as movement.

“I have hopes for him. I expect him to be really good.”

Though Mitchell returned to the field in Week 10 last season, he did not look the same. He ran with caution. He didn’t have the same level of acceleration that had raised eyebrows and turned heads his rookie season when he averaged 8.4 yards per carry and 10.3 yards per catch.
