Yost thinks Royals 'making great progress' with Brett, Grifol as coaches

It’s been almost one month since George Brett and Pedro Grifol were hired as/ the new hitting coaches — the move was made on May 30 — and manager Ned Yost said he couldn’t be happier.

“I think it’s gone great — I think Georgie has done a great job, I think him and Pedro both have done a great job,” Yost said. “They’re tireless workers, they’re on top of everything, I think we’re making great progress in a lot of areas.”

The Royals are 14-9 since the move. They are averaging 3.9 runs per game, which is down from the 4.0 runs per game they were averaging before previous hitting coaches Andre David and Jack Maloof were reassigned.

However, third baseman Mike Moustakas and first baseman Eric Hosmer — two young players the team hoped Brett and Grifol would have the most impact on — have seen slight upticks in their production since the change.

As of Sunday, Moustakas’ batting average was .237 in 18 games since the change, compared to .187 in 43 games. Hosmer was batting .318 with two home runs and 14 RBIs in 22 games since the change, compared to a .262 batting average with one home run and 13 RBIs in 48 games.
