KANSAS CITY, Mo. — Felix Hernandez thought his fastball command was the key against Kansas City.
Scott Servais thought it was his ace's curveball.
Both gave the Royals fits Tuesday night.
The Mariners' star right-hander bounced back from a miserable start in San Francisco to pitch into the sixth inning, and Guillermo Heredia homered to lead a big offensive outburst as Seattle rebounded from a blowout loss to the Royals with an 8-3 victory that evened their series.
"He was attacking the strike zone, and we talked about getting his curveball going and he really did," Servais said. "Much more in control tonight and had good results."
Hernandez (2-1) allowed three runs, six hits and a walk in 5 2/3 innings, leaving primarily because his pitch count was driven up. His only big mistake came in the fourth, when Mike Moustakas turned on a 2-1 pitch and sent a two-run homer screaming into the right-field fountains.
But that was also just about the only offense the Royals could muster, one night after they piled up 10 runs to back a near-no-hit performance by Jakob Junis and their bullpen.
Eric Skoglund (0-1) was hardly as efficient or effective. The lanky left-hander allowed five runs, six hits and two walks in 4 2/3 innings. He was clearly rusty from a nearly monthlong layoff caused by rainouts and weather problems, hitting the first batter he faced and three in all.
"I felt better as the game went on," he said. "I made some mistake pitches early in the game that cost us, but as the game went on I felt better and the confidence is there."
As for not pitching in a game since an exhibition March 17?
"It is what it is, man. It's baseball. It's part of it," Skoglund said. "I'll just go out there and do everything I can to help the team win."
Royals pitchers have plunked six Seattle hitters through the first two games of the series.
"(Skoglund) looked like he was rusty but our guys were putting good swings on him," Servais said. "Up and down the lineup, we created a lot of traffic."
Jean Segura had three hits and drove in two runs, and Mitch Haniger and Kyle Seager also had two RBIs as the Mariners put together a pair of three-run innings to pull away.
"The whole offense was really good tonight," Hernandez said.
The Royals tried to rally in the sixth, when they loaded the bases against Dan Altavilla. But the Mariners' reliever struck out Paulo Orlando to preserve their 8-3 advantage, and James Pazos and closer Edwin Diaz wrapped up the last couple frames in tidy fashion.
"There are a lot of things we can build on off of tonight," Royals manager Ned Yost said.
