The news isn’t surprising as GM Ross Atkins said after the season that manager Charlie Montoyo’s entire staff would be invited to return for 2021, but no official announcement finalizing the group has come yet.
Martinez, who revealed the news through the Pro Hitting Baseball facility he runs in Knoxville, is the first known extension. Some coaches were already signed through the upcoming season.
Martinez was hired as hitting coach in November 2018, replacing the fired Brook Jacoby. Last year, he worked closely with Dante Bichette, hired as a major-league coach just before the season after spending both spring training and summer camp with the club.
“We were right on the same page” from the outset, Bichette said back in August. “Me and him are like inseparable. We go eat together, we talk hitting, he'll send me a video of a hitter at two o'clock in the morning, man. He's really a studied guy. He knows the numbers a lot better than I do, the new analytics and all that. So he helps me with that. He helps me with swings. I help him with approach. We're teaching each other. It's really been fun.”
