The Walk Off: Cubs continue crushing every team in their path

Welcome to The Walk Off, the nightly MLB recap from Big League Stew. Here we'll look at the top performers of the night, show you a must-see highlight and rundown the scoreboard. First, we start with a game you need to know about.

Everyone knew the Chicago Cubs were going to be very good this season. That's why way more pundits than usual were in agreement when predicting a World Series champion, with 44-percent actually picking the Cubs to win it all. That's also why Las Vegas continues making the Cubs the odds on favorite to end their historic championship drought.

As we've learned over the years, sometimes expectations don't match results. But in the case of the Cubs, the results are somehow surpassing the expectations. On Wednesday, they became the first team in MLB to reach 20 wins when they defeated the Pirates 6-2. The victory also completed a three-game sweep at PNC Park and ran their division lead to a league-best six games

The Cubs are not fooling around. Even with slugger Kyle Schwarber lost for the season. Even with Jason Heyward banged up and off to a slow start. Even with 16 of their first 26 games away from Wrigley Field, they are dominating everybody.

On Wednesday, they only won by four runs. But it was never in doubt with Jon Lester refusing to fold and Chicago's offense making Pittsburgh pay for every mistake. Three of the Cubs' six runs were unearned, but they all counted. That's just what the Cubs do. They wear teams out and they make teams play near perfect baseball just to have a chance. That puts a lot of pressure on the opposition, and more times than not their opponents have crumbled.

It's scary to think how good the Cubs are right now, and it's scarier to think how good they'll be if all of their players start clicking at once.

TOP PERFORMERS

Corey Kluber: Cleveland's ace was rock solid on Wednesday, going the distance in the Indians 4-0 victory against the Tigers. Kluber battled some traffic, allowing five hits and walking two. But he made good pitches when he needed to. That includes the seven strikeouts he racked up. The complete game was Kluber's eighth, all coming since 2014. The shutout was his second.

Steven Matz: Sometimes Matz can be the forgotten man in discussions about New York's dominant rotation. He made himself the center of the conversation on Wednesday, pitching 7 2/3 scoreless innings in the Mets 8-0 win over the Braves. Matz allowed just two hits while striking out eight and lowering his ERA to 2.83. Lucas Duda also homered twice as the Mets won for the 10th time in 12 games.

Daniel Murphy: After a forgettable World Series against Kansas City last fall, Daniel Murphy did his best to put it behind him in this series against the Royals. After homering in Tuesday's loss, Murphy paced a Nationals 13-2 victory on Wednesday with four hits, four runs scored and three RBIs. Murphy's big hits included his fourth home run of the season and his 10th double, which knocked in two.

The Astros: It was a team effort in their 16-4 dismantling of the Twins. Six different players drove in at least two runs. Among them were Jose Altuve, Carlos Correa and Jason Castro, all of whom homered as well. In total, Houston collected 14 hits and seven walks en route to a much-needed and much-enjoyed victory.

MUST-SEE HIGHLIGHT

The Mariners hit three home runs in Wednesday's 9-8 win against the A's. The most impressive, by far, was this moonshot of a two-run blast from Nelson Cruz. That ball landed in the rarely reached center field seats in Oakland. More importantly, the runs were needed on an afternoon where Felix Hernandez struggled, allowing eight runs (four earned) in four innings.

THE REST OF THE SCOREBOARD

Reds 7, Giants 4: The rough start for San Francisco's Jake Peavy continued here. The 34-year-old right-hander allowed seven earned runs in six innings, raising his ERA to 9.00 through six starts.

Angels 7, Brewers 3: Mike Trout homered, tripled and knocked in two as the Angels avoided a sweep in Milwaukee.

Rockies 2, Padres 0: With Jorge De La Rosa on the DL, Tyler Chatwood is emerging as Colorado's ace. He tossed eight scorless innings to earn his fourth win and lower his ERA to 2.15.

Yankees 7, Orioles 0: The Yankees snapped a six-game losing streak thanks to a strong effort from CC Sabathia. The veteran left-hander tossed seven scoreless innings.

Blue Jays 4, Rangers 3: Make that two straight walkoff wins for the Jays. This time Russell Martin came through with a bases-loaded single in the ninth.

Marlins 4, Diamondbacks 3: In a game highlighted by a selfie, Miami gets a big win. Giancarlo Stanton clubbed a two-run homer.

Rays 8, Dodgers 5: After being buried by Dodgers homers on Tuesday, the Rays battled back with four of their own in Wednesday's win.

Red Sox 5, White Sox 2: 'Big Papi' David Ortiz homered and drove in three as Boston evened the three-game series.

Cardinals 5, Phillies 4: St. Louis overcame a four-fun deficit with a three-run fifth inning and a two-run ninth inning. Matt Holliday played hero, lacing a walk-off single.
