The Chicago Cubs got some help to record a wild win over the Philadelphia Phillies in MLB, while Max Scherzer dominated.
A throwing error by the Phillies allowed the Cubs to clinch a 5-4 walk-off victory as Albert Almora Jr. came home to score in the 13th inning and send Wrigley Field into a frenzy.
After the Milwaukee Brewers' 5-4 win at the St Louis Cardinals, the Cubs (16-12) hold a game-and-a-half lead in the National League (NL) Central.
Scherzer led the way for the Washington Nationals, helping his team to a 4-2 win against the Arizona Diamondbacks.
The Cincinnati Reds claimed a 4-2 win over the Pittsburgh Pirates, the Oakland Athletics beat the Minnesota Twins 8-5 and the Texas Rangers were 10-4 victors against the Houston Astros.
The Kansas City Royals were downed 8-3 by the Chicago White Sox, the Colorado Rockies needed 11 innings to get past the San Diego Padres 3-2 and the Baltimore Orioles beat the Boston Red Sox 8-3.
The Tampa Bay Rays had a 5-1 win over the Miami Marlins and the Seattle Mariners cruised past the Los Angeles Angels 11-3.
Rain washed out the Cleveland Indians-Detroit Tigers and New York Mets-Atlanta Braves games.
Nationals pitcher Scherzer was dominant on the hill against the Diamondbacks. Scherzer struck out 11 and allowed just one run and two hits with two walks over seven innings. He also went two-for-three at the plate with an RBI single in the second inning to open the scoring.
Orioles star Manny Machado crushed a 466-foot home run that left Fenway Park.
MERRIFIELD, ROYALS STRUGGLING
Royals second baseman Whit Merrifield went 0-for-four with three strikeouts as Kansas City's leadoff hitter. Merrifield saw his average drop to .222 this season as the Royals have struggled mightily, going 9-18 so far and just 2-11 in the American League Central.
YANKEES AT CUBS
The Yankees (17-9) make a rare trip to Wrigley Field as Michael Pineda (3-1, 3.14 ERA) gets the start while the Cubs will turn to Kyle Hendricks (2-1, 4.18). The two teams have played just 13 times during the regular season, the last time coming in May 2014 when they split a pair of games at Wrigley Field. Former Cubs Aroldis Chapman and Adam Warren, now with the Yankees, will receive their World Series rings Friday.
