BALTIMORE — Dylan Bundy set a dubious modern-day record, yielding four homers and leaving without getting an out, part of a 10-run first inning that propelled the Kansas City Royals past the hapless Baltimore Orioles 15-7 Tuesday night.

Bundy (1-5) was lifted after allowing five hits and two walks to the only seven batters he faced. That was more than enough damage to send the Orioles to their season-high seventh straight defeat and 19th in 22 games.

Jon Jay started the onslaught with a leadoff single before Jorge Soler, Mike Moustakas and Salvador Perez homered in succession.

Two walks and a home run by Alex Gordon followed, ending Bundy’s night after just 28 pitches. It marked the first time in the current era (1908-present) that a pitcher gave up four home runs during an outing in which he did not retire a batter, according to baseball-reference.com.

After compiling a 1.42 ERA after his first five starts, Bundy has given up 19 earned runs over his last three games to boost his ERA to 5.31.

Following Bundy’s departure, the Royals did not let up.

Alcides Escobar greeted Mike Wright with a single, the eighth straight batter to reach base.
