Giants assure NL West lead after beating Dodgers, Blue Jays stunning return

The San Francisco Giants reclaimed the National League (NL) West lead with a dramatic 3-2 walk-off victory over rivals and World Series champions the Los Angeles Dodgers.

Sole possession of top spot was on the line as the Giants and Dodgers clashed in a heavyweight MLB showdown in San Francisco on Friday.

The score was deadlocked at 2-2 until a bizarre walk-off throwing error lifted the Giants past the Dodgers in the 11th inning.

With the bases loaded in the 11th and two outs, Buster Posey appeared to have hit an inning-ending groundout, but Trea Turner's throw went wide of Will Smith, whose toe came off the bag.

Posey was initially ruled safe, and it stayed that way despite a lengthy Dodgers (85-50) review – the Giants (86-49) moving back to the top of the NL West again.

Comeback of the year?

The Toronto Blue Jays emerged from the jaws of defeat in stunning fashion, somehow conquering the Oakland Athletics 11-10. Toronto – chasing the last Wild Card spot – trailed 8-2 entering the eighth inning at home to fellow playoff hopefuls the A's. Lourdes Gurriel Jr. hit a game-tying grand slam after a two-out rally. Mark Canha's two-run homer restored Oakland's advantage in the top of the ninth, but Marcus Semien delivered an incredible walk-off three-run homer in the bottom of the inning. Gurriel became just the third Blue Jays player ever to hit three grand s lams in a season after Edwin Encarnacion (2015) and Darrin Fletcher (2000).

The Detroit Tigers lit up the Cincinnati Reds 15-5 behind Dustin Garneau's two-run homer and solo shot, plus Robbie Grossman's three-run blast.

Kyle Schwarber hit a lead-off homer in the opening inning to fuel the Boston Red Sox's 8-5 victory at home to the Cleveland Indians. Hunter Renfroe added a three-run homer for the Red Sox, who have won three straight games.

Keuchel's woes continue

Dallas Keuchel struggled again as the Chicago White Sox went down 7-2 to the Kansas City Royals. Keuchel allowed six runs in three innings – the 2015 American League (AL) Cy Young winner has a 7.26 ERA through his past 11 starts. He gave up five earned runs, seven hits and two walks with just one strikeout against the Royals.

Arenado homers twice as Wainwright and Molina celebrate milestone

St Louis Cardinals star Nolan Arenado recorded his 21st multi-homer game since entering the majors in 2013 – tied for the second most alongside Bryce Harper in the NL in that span, behind Giancarlo Stanton (22). The Cardinals crushed the NL Central-leading Milwaukee Brewers 15-4. Cardinals team-mates Adam Wainwright and Yadier Molina started together for the 300th time – the fourth most prolific battery in history.

Friday's results 

With both teams vying for a Wild Card berth, the Blue Jays (71-62) and Athletics (74-61) will continue their series on Saturday. Jose Berrios will start for the Blue Jays as the A's counter with Paul Blackburn.
