A man posing as ex-MLB star Tim Lincecum scammed a Baltimore Ravens player out of autographed gear ... and he almost got it away with it if it weren't for the NFL'ers agent -- this according to cops.
Here's the deal ... authorities in Monroe County, Penn. say former NFL 1st-round pick Hayden Hurst contacted them last month to report he had been scammed.
Cops say Hurst told them that on or around May 19, 2019 -- he was contacted by a Twitter account he believed belonged to former SF Giants superstar pitcher Lincecum.
