Boston Red Sox outfielder Jackie Bradley Jr. has always run hot and cold. Now, he's working with the same hitting coach as J.D. Martinez to avoid falling into his famous cold streaks.

According to WEEI.com's Rob Bradford, Bradley began working with Craig Wallenbrock, who has worked with J.D. Martinez as a hitting coach.

Martinez is already considered a positive resource for hitting advice with the team. But around the All-Star Break, Martinez invited Bradley to start working directly with Wallenbrock, Bradford reports. Now that the season is over, Bradley has gone all-in and begun working out in Los Angeles to get the most out of his new approach to hitting.

The early results? Bradley is starting to realize how rough his current approach to the plate actually is.

"This is the first time I heard any of this stuff," said Bradley told Bradford. "What I've been taught my whole life is completely wrong. It's scary to say that, but it's wrong. I feel fortunate enough to make it this far doing it wrong."

Wallenbrock has already worked wonders with Martinez, who was told that his swing "was the worst they'd seen from a major leaguer" when he started working with the coach.

Martinez was 26 when he started working with Wallenbrock. He's since gone on to evolve into one of the top hitters in baseball. Now, the hope is that Bradley can make a similar leap with new coaching.

At the very least, his manager is looking forward to the results.

"This is going to be good," Alex Cora told Bradford. "He felt it and he understands who he is now and I don't think the whole -- like the roller coaster Jackie Bradley will happen again. He understands who he is. And with that offensive approach over 162 games, we'll see what happens."

The early results from Bradley's now coaching have been apparent. Bradley's 2018 batting average had dipped below .200 for much of May and had barely risen above by the time the All-Star Break came around. After that, though, Bradley's average steadily improved, finishing out with a .236 mark.

His progress really began to show in the postseason. His average sat at .200, but his power strokes against the Houston Astros wound up earning him ALCS MVP honors.
