The Cubs have played 112 games this year, meaning they have exactly 50 left to play.
They have just 1 walk-off win, on Christopher Morel's 10th-inning sacrifice fly that beat the Brewers, 4-3, on June 1, in their 50th game of the season.
Each of the 29 other big league teams has at least 2 walk-off wins.
4 teams have 2: the Angels, Athletics, Rangers and Rockies.
The Yankees have 11, 3 more than anyone else. The Orioles, Padres and Twins have 8.
The average of all teams other than the Cubs is 4.6.
According to my research, the Cubs have 950 total walk-offs in regular-season National League games: 100 before the Modern Era, 850 since it began in 1901, including 746 at Wrigley Field.
They had none in 1876 and 1877, then 1 in 1878-79, 1881, 1885 and 1893-94.
They have had just 1 only once since the last of those years: in 1955, when the Cubs finished 72-81-1.
That lone walk-off came in their 110th game, the second on a doubleheader at home against the Pirates, on Wednesday, Aug. 3.
After splitting 2 games vs. the Reds on the Fourth of July, the Cubs had been 44-36 and in second place -- though 12.5 games behind the league-leading Dodgers (55-22).
Then the Cubs began one of their all-too-frequent swoons. They lost 2 games to end their homestand, then dropped 9 in a row at St. Louis, New York, Philadelphia and Brooklyn.
After a win over the Dodgers on July 20, they immediately lost 6 more, including 4 straight at Pittsburgh.
They swept the Giants in a doubleheader at home on July 27, but a loss the following relegated the Cubs to sixth place, at 48-54.
Back-to-back losses to the Phillies came next, but the Cubs managed to split the series by winning both ends of a doubleheader on the final day of July.
On Monday, Aug. 1, only 3,194 were on hand to watch the Cubs (50-56) host the last-place Pirates (38-68).
Dale Long gave Pittsburgh a 4-2 lead by smacking a 2-run homer in the sixth inning. The visitors added a run in the ninth on a single, a bunt and another single. That proved decisive when the Cubs got a 2-run homer from Randy Jackson in the bottom but could not score again.
There were just 1,788 in the seats when the teams met again on Tuesday.
The Pirates jumped on Cubs starter Bob Rush for 3 runs in the first.
The Cubs pulled even with a run in their half of the inning, then 2 more on a single by Rush in the second.
With 2 out and a runner on first in the fifth, Rush surrendered a tie-breaking triple.
In the bottom half, Rush drew a leadoff walk. After misplays on consecutive bunts, the bases were loaded. The next batter struck out, but Ernie Banks walloped a grand slam, his fourth of the season.
The Cubs scored twice more before the inning ended, the last run on a bases-loaded walk to Rush. He wound up going the distance, allowing 8 hits and walking 3 as the Cubs won, 12-4.
GAME 1 COLLAPSE
Maybe it was the resounding victory the previous day.
Maybe it was the chance to see 2 games for the price of one.
Whatever the reason, the doubleheader on Wednesday lured 8,805 to Wrigley Field.
In Game 1, Banks homered leading off the second.
The Pirates tied the score in the fourth, on a double by Roberto Clemente and a single by Frank Thomas.
Randy Jackson opened the Cubs' seventh with a single and was bunted to second. After a strikeout, pitcher Jim Davis singled in Jackson, giving the Cubs the lead again, 2-1.
Davis gave up a leadoff single in the eighth, then retired 3 in a row.
The first batter in the ninth singled, too. Davis coaxed a fly out, then yielded a single.
Manager Stan Hack summoned Hal Jeffcoat from the bullpen to face pinch hitter Jerry Lynch, who slammed a double that scored both runners.
The inning ended in bizarre fashion: an intentional walk, a forceout at second, then Lynch out trying to steal home.
The Cubs managed only 2 strikeouts and weak pop fly in their half, saddling them with a 3-4 loss.
The Pirates drew first blood in Game 2, scoring in the second on a walk, a groundout and a 2-out single off Sam Jones.
The Cubs needed only 2 batters to tie the game, as Jim King and Randy Jackson hit back-to-back triples.
An intentional walk and line drive double play left Jackson on third with 2 out. He trotted home when Jones singled.
The next inning, Gene Baker singled and was bunted to second. A single by Banks put runners on the corners, and a double by King drove home both of them: Cubs 4, Pirates 1.
The score was the same when Jones yielded a double to the first batter in the seventh. A fly ball and a groundout enabled the runner to score: 4-2.
Jones then hit a batter, walked the next and served up an RBI single: 4-3.
Lefty Harry Perkowski took over from Jones and gave up a single to pinch hitter Jack Shepard: 4-4.
A forceout ended the inning.
MANY RUNNERS, NO RUNS
The Cubs had runners on first and second with 1 out in their half. The rally died when Frank Baumholtz popped up and Ernie Banks hit into a forceout.
The Pirates did the same in the top of the eighth. Perkowski struck out pinch hitter Roberto Clemente and got the next batter to ground out.
The Cubs stranded a man on second in the eighth and left one on first in the ninth.
In the 10th, Banks singled and so did King, but Banks was thrown out trying to reach third. King advanced to second, prompting an intentional walk. A fly ball and a groundout kept the game going.
Clemente, who had stayed in the game, singled off Perkowski to begin the Pirates' 11th. A forceout and a double play followed.
The Cubs got a 1-out single in their half. A forceout and a popup came next.
The 12th was Perkowski's sixth inning on the mound. He made quick work of the Pirates: ground ball, fly ball, ground ball.
Vern Law began his sixth inning by getting Banks to ground out. King, up next, rapped his fourth hit and second double.
Law walked Jackson intentionally and got a fly ball for the second out.
That brought up Harry Chiti. The 22-year-old catcher, in his first full season, had gone into the today batting .239, then had gone 0 for 5, leaving 6 runners on base.
But this time he lined a ball over the head of the center fielder. King raced home and the Cubs won, 5-4, after 3 hours and 17 minutes, at 7:30 p.m.
The game was the 120th of Chiti's career.
The walk-off was his first.
He never had another, in 109 more games as a Cub and 273 with the Athletics, Tigers and Mets.
His career slash line was .238/.294/.365, for an OPS of .659 and an OPS+ of just 77.
Perkowski's pitching line in the walk-off win was 5.1 innings, 0 runs, 4 hits, 1 walk and 1 strikeout.
It was the 32-year-old's 18th appearance in his first season as a Cub. He had spent 7 years with the Reds, for whom he had gone 12-10 and 12-11 as a starters in 1952 and 1953.
After Perkowski had slumped to 2-8, with a 6.11 ERA, in 1954, he had been traded to the Cubs, with Jim Bolger and Ted Tappe for Johnny Klippstein and Jim Willis.
Perkowski had been battered in 3 starts as a Cub in April and May: 17 runs, 13 earned, in 9.1 innings.
After his performance in the walk-off win, he was given another start, 8 days later. He lasted only 3 innings, in which he surrendered 4 runs, all earned, on 6 hits.
He pitched in 6 more games before the season ended, all in relief, including 5.2 shutout innings against the Cardinals on Sept. 3.
He yielded 3 runs on 2 hits and 3 walks in 2 innings on Sept. 9, then no runs and no hits in 2.1 innings on Sept. 11.
On Sept. 18, at home against the Reds, Perkowski entered the game with 2 outs and the bases loaded.
The first batter he faced singled, scoring 2 runs.
The second singles, scoring a third.
The third singled, scoring a fourth.
Perkowski then exited, never to pitch in another big league game.
He spent 1956-58 with Cubs farm teams in Los Angeles, Tulsa, Memphis and Fort Worth, then 2 more years in Denver, which affiliated with the Tigers in 1960, Perkowski's final year.
He was 38 when he retired.
His Major League record was 33-40, with a 4.37 ERA. In 10 minor league seasons, he was 117-63.
FEW WALK-OFFS IN LATER SEASONS
Since 1955, the Cubs have finished just 1 season with as few as 2 walk-off wins: 1997.
On Aug. 3, in their 112th game of the year, they beat the Dodgers, 4-3, thanks to Sammy Sosa's 2-out, 2-run homer in the 12th inning.
Then On Aug. 28, in Game No. 134, they beat the Marlins, 4-3, on Shawon Dunston's 2-out RBI single in the 10th.
The Cubs had 3 walk-off wins in the 60-game 2020 season. They also had 3 in 1943, 2006, 2010 and 2013.
The most walk-off wins the Cubs had in a season was 14, in 1930.
They had 13 in 2015, 12 in 1915 and 1932, 8 in 11 seasons and 10 in 7, for a total of 19 with double digits.
The 13 in 2015 were their most since they had 11 in 1996.
