Moore allowed three runs on five hits in eight innings to piggyback off his strong performance in his MLB debut against Detroit on June 22, in which he surrendered three runs on six hits in seven innings. But the Mariners managed just four hits and finished 0-for-4 with runners in scoring position.
The most impressive facet of Moore's performance on Monday was his in-game adjustments to an aggressive Royals lineup. After attempting to pump in first-pitch fastballs for strikes early, he worked backward in his approach and tried to keep the Kansas City hitters off balance with a healthy dose of off-speed pitches early in the count.
"He made some adjustments," Servais said. "Sometimes when Plan A isn't working, you've quickly got to shift and go to plan B. And he did. He got more of his secondary pitches. He got the curveball, slider working. He's got a very good changeup, he went to that as well, to get them off the fastball a little bit."
And the results were positive, as he retired 18 of his last 20 batters after giving up two runs on three hits to the first six batters faced.
"I'm really impressed with how he kept his composure," Servais said. "[He] just keeps going after them, attacking, and his ability to make adjustments is huge for a young pitcher and it's going to serve him well in the future."
