Toronto Blue Jays star Vladimir Guerrero Jr treated his home fans to a 3-2 walk-off win against the New York Yankees in extra innings.
Guerrero, 23, is considered one of the best young hitters in the sport, and he was one of only three players in the game to tally more than one hit on Monday.
After a Gleyber Torres sacrifice-fly and an Isiah Kiner-Falefa solo home run gave the Yankees a 2-0 lead heading into the fourth inning, singles to Bo Bichette and Guerrero set the table for Teoscar Hernandez's game-tying two-run double.
That 2-2 score would hold for the rest of regulation as both bullpens delivered five consecutive scoreless innings, and the Blue Jays had no interest in dealing with AL MVP favourite Aaron Judge in the 10th frame.
With runners on first and second base and two outs, the Blue Jays opted to intentionally walk Judge as he remains one home run away from the Yankees' and American League single-season record of 61, set 61 years ago by Roger Maris in 1961. The next batter, Anthony Rizzo, would harmlessly ground-out with bases loaded.
New York could have walked Guerrero with two outs and a runner on second base, but chose to pitch to him, and were punished with a walk-off single.
The win trimmed the Yankees' lead in the AL East to seven-and-a-half games, although the Blue Jays will likely make the playoffs regardless as they lead the race for the AL Wildcard spots.
Braves rookie pitches a shutout
The Atlanta Braves appear to have unearthed another stud rookie pitcher, with 23-year-old Bryce Elder pitching a complete game shutout in his side's 8-0 win against the Washington Nationals.
In just the eighth start of his career, Elder made it through all nine innings in 106 pitches, allowing six hits and one walk with six strikeouts. His emergence is a bonus for the Braves, who already have both contenders for National League Rookie of the Year in starting pitcher Spencer Strider and center-fielder Michael Harris II.
Albeit a small sample size, Elder now boasts an ERA of 2.76, and he has rattled off four consecutive quality starts, including a 10-strikeout outing against the Miami Marlins.
Santander hits two homers in high-scoring Orioles win
Anthony Santander hit two of the Baltimore Orioles' four home runs in a 14-8 win against the Boston Red Sox, with the two sides combining for 29 hits.
Of the 18 starters from both sides, only three players failed to get a hit in the game, while Santander, Cedric Mullins, Austin Hays, Rougned Odor and Kyle Stowers all collected at least two each for the Orioles.
Star 21-year-old prospect Gunnar Henderson also had a strong day for Baltimore, hitting a two-run home run and drawing three walks.
