Moustakas was 2-for-4 with a solo home run and a two-run single in Thursday night's 4-3 win over the Yankees. In the top of the ninth inning, he also made a spectacular play on a ground ball hit by Alex Rodriguez to end the game.
The night was an example of what's becoming a trend for the young third baseman. In his last 10 games coming into Friday night, Moustakas was hitting .432 with two home runs and eight RBIs, and he had gone hitless only once.
And Thursday night's spectacular play wasn't the first this season. Moustakas has made several gems at the hot corner, and the many that have come at home have elicited the same response from the crowd.
Royals manager Ned Yost said Moustakas has worked hard to improve his defense from last season.
"It's definitely improved, but it's improved for a reason, because he's worked extremely hard at it," Yost said. "He spent the whole winter getting himself in great shape and started working from Day 1 in Spring Training. It's a progression that still happens day to day here."
Moustakas is far from reaching the popularity of fellow third baseman George Brett -- the Hall of Famer who will be honored on Saturday with a Mini Pine Tar Bat promotional giveaway to the first 20,000 fans -- but Moustakas has one thing Brett never did.
