KANSAS CITY, Mo. (AP) — Edwin Encarnacion homered twice during an eight-run sixth inning, two of five homers for the hot-hitting Seattle Mariners during a 13-5 victory over the Kansas City Royals on Monday night.

The Mariners have scored five or more runs in 11 of their first 12 games and have 32 homers in that span, the most ever by a team a dozen games into the season. The St. Louis Cardinals had 31 in 2000, according to STATS.

Encarnacion is the first Mariner to homer twice in an inning since Bret Boone and Mike Cameron both did it May 2, 2002 against the White Sox. Cameron tied a major league record with four homers in that game. The last player with a multihomer inning was Mark Trumbo of the Angels on April 15, 2016 at Texas.

It’s the second time in his career that Encarnacion has homered twice in an inning, also accomplishing it on July 26, 2013 with Toronto. He’s the fifth player to homer twice in an inning more than once, joining Alex Rodriguez, Jeff King, Andre Dawson and Willie McCovey, per STATS.

The Mariners improved to 10-2, the first team in the majors with double-digit victories.

Roenis Elias (1-0) pitched three scoreless, hitless innings in relief, helping Seattle cover when Felix Hernandez left after one inning with an illness.

Homer Bailey (0-1) allowed seven runs in five-plus innings.

Whit Merrifield led off the first inning with an infield single, extending his hitting streak to 29 games dating to last season. Merrifield’s streak is one shy of George Brett’s club record, set when he hit .390 in 1980.

Daniel Vogelbach connected leading off the second to give the Mariners a home run in their 12th straight game, a club record. They became the fourth AL team to do that since 1908.

Jay Bruce and Dylan Moore also went deep for Seattle.
