Curtis Mead's breakout Major League Baseball season has continued despite the Washington Nationals blowing an eight-run lead against San Francisco to fall to a 11-10 defeat.
The Adelaide product, traded to the Nationals from the Chicago White Sox in late March, lodged his 10th home run but it wasn't enough to stop a stunning fightback from the Giants.
Bryce Eldridge launched a walk-off grand slam with no outs in the bottom of the ninth inning, with the Giants rallying from a 9-1 deficit to score 10 runs over the final two innings to secure the shock win.
After Matt Chapman and Rafael Devers had homered as part of a five-run eighth that got the Giants back in the game at 9-6, the Nationals added an insurance run in the top of the ninth when Mead homered off left-hander Reiver Sanmartin, who was making his San Francisco debut.
Down four, Luis Arraez and Chapman led off the last of the ninth with back-to- back doubles, closing the gap to 10-7, before Gus Varland walked Devers to bring the potential tying run to the plate.
Jung Hoo Lee then greeted Mitchell Parker (2-3) with a single, loading the bases for Eldridge, who took two balls before lofting a towering drive to right that barely cleared the brick wall at Oracle Park for the game-winner.
Retiring six batters Sanmartin, who pitched the eighth and ninth innings, was credited with the win, which stopped the Nationals' three-game series sweep.
Meanwhile, Travis Bazzana's Cleveland Guardians also had a day to forget, the New York Yankees completing a three-game sweep with an 8-4 victory.
Jazz Chisholm Jr had a two-run triple and three RBIs and Trent Grisham scored three times, with the Yankees now 10-4 since May 24, boasting the second-best record in the American League behind the Tampa Bay Rays.
New York outscored the Guardians 18-11 during the series, posting their first sweep of Cleveland since April 2022 and stopping the Guardians' streak at 31 consecutive series.
Grisham tripled and provided the go-ahead run on Jose Caballero's sacrifice fly in the sixth inning, when the Yankees scored three times to go up 6-3.
New York blew the game open in the seventh, making it 8-3 on Caballero's single that scored Grisham and Chisholm's RBI fielder's choice.
Yankees starter Carlos Rodon improved his strong career numbers against Cleveland, striking out seven.
Bazzana scored a run in the fourth innings, but the second baseman also botched a grounder in the second innings, allowing Chisholm to score and build an early 3-1 lead.
