Mariners pitching coach Mel Stottlemyre Jr. credits Taijuan Walker’s success to embracing mechanical changes | The Seattle Times

“At that point, he decided it was time to make some adjustments and changes,” Stottlemyre said.

The following day the two were out early before the game, playing catch and working on the changes that features a different leg kick and more hip turn to help him use his legs more and drive down the slope of the mound. It’s been a daily routine since then. They’ve spent hours together going over the changes. They were inseparable on the field, in the weight room and in front the video monitors.

“These are drastic,” Stottlemyre said. “These are not easy. It’s the tail end of the season on a club that’s possibly in a pennant run and to go out and try to recreate a delivery is not easy to do. It’s a testament to the work that he did – the dry work, the video work, watching other guys do it. He’s been relentless with the work and in our bullpens just trying to put it all together. I’m so proud of him.”
