Brent Rooker hit a two-run home run off Dylan Coleman in the bottom of the ninth inning to give the Oakland Athletics a 6-4 win over the Kansas City Royals on Monday night in a matchup of teams with the worst records in the major leagues.

Zack Gelof, Jordan Diaz and Shea Langeliers also went deep for the MLB-worst Athletics (35-90), who snapped a three-game skid and won for the second time in 10 games.

The A’s led most of the game, but squandered a 4-2 lead in the eighth when the Royals scored twice off Lucas Erceg, tying the game.

Kansas City had another runner in scoring position when Michael Massey singled and appeared to steal second with two outs. Massey was initially ruled safe, but the call was overturned after video replay, ending the inning.

Ryan Noda, just activated off the disabled list, led off the ninth and was hit by a pitch from Coleman (0-2). Rooker then slammed a 2-0 slider into the seats in left field for his second game-ending homer of the season.

Bobby Witt Jr. hit his 25th home run for Kansas City. The Royals (40-87) have dropped six of seven.

Gelof broke a 1-1 tie when he crushed a first-pitch slider from Alec Marsh over the wall in center leading off the third. It was Gelof’s sixth home run this month and ninth in his first 32 games, making Oakland’s hard-hitting rookie the quickest player in franchise history to reach that mark.

After Witt’s solo home run off starter Paul Blackburn in the sixth trimmed Oakland’s lead to 3-2, Langeliers countered in the bottom of the frame with his 12th home run, a 456-foot drive.

Trevor May (4-4), the fifth – and last – pitcher used by the A’s, retired three batters and earned the win.
