SEATTLE (AP) -- Austin Jackson hit a bases-loaded single in the 10th inning to give the Seattle Mariners a 6-5 victory over the Baltimore Orioles on Tuesday night, marking the first time since baseball expanded to 30 clubs that all 15 home teams won on the same day.
Nelson Cruz and Mark Trumbo homered for the Mariners. Cruz extended his hitting streak to a career-high 21 games, matching Troy Tulowitzki for the longest streak in the majors this season, but exited before the seventh with neck spasms.
Jackson's single off reliever T.J. McFarland (0-2) down the right-field line scored Logan Morrison from third and finished off the major league schedule for the night.
The last time home teams went undefeated on a day with more than one game was an 8-0 record on Aug. 28, 2008 - although road squads were 7-0 on April, 2, 2013, according to STATS.
Arizona and Tampa Bay joined the majors in 1998, bringing the total to 30 teams.
STATS said previously the best performance by home teams had been 11-0, accomplished six times - three in the 1800s. The most recent occasion was Sept. 16, 1989.
Morrison led off the 10th with a bloop double down the left-field line. Brad Miller followed with a single that put runners at the corners.
Fernando Rodney (5-4) pitched a perfect inning for the win.
Adam Jones and Chris Davis hit back-to-back homers to tie the game in the eighth. Jones' two-run shot chased reliever Tom Wilhelmsen. Davis greeted Joe Beimel with a towering drive to right that made it 5-all.
Seattle had a 4-2 lead after the first thanks to two homers. Cruz hit a solo shot with two outs and Trumbo added a three-run drive later in the inning.
Kyle Seager added another run for Seattle with a second-inning sacrifice fly to score Miller, who doubled leading off the inning and moved to third on Jackson's single.
The Orioles took a 2-0 lead in the top of the first on a two-run single by Jonathan Schoop.
Baltimore loaded the bases with two outs before Schoop's hit, but Mariners starter Taijuan Walker quickly rebounded and later retired 11 straight.
Walker allowed two runs in six innings. He struck out six and walked one.
Chris Tillman gave up five runs and eight hits over 2 1-3 innings in an unusually rough outing against the Mariners. The former Seattle second-round draft pick entered 6-0 with a 2.09 ERA in seven career appearances against his former club.
Tillman was struck on the back of his right arm by a line drive off the bat of Robinson Cano in the first inning. After a brief delay and a few warmup pitches, Tillman was cleared by a trainer to continue.
Mariners: LHP Charlie Furbush (biceps) is not quite ready to begin a rehab assignment and will throw another bullpen Saturday with the team in Boston. The reliever has no structural damage, but does feel a slight pinching sensation when he throws.
Orioles: RHP Chaz Roe is expected to get a cortisone shot for his shoulder inflammation, but is still on track to return from the disabled list Aug. 25, manager Buck Showalter said.
Mariners: RHP Hisashi Iwakuma pitches Wednesday afternoon against Baltimore as the Mariners close out a six-game homestand.
Orioles: Baltimore wraps up a nine-game road swing, sending Kevin Gausman to the mound looking to improve his 2-3 record and 4.56 ERA.
