Rickwood Field, the first concrete-and-steel ballpark in the minor leagues, opens in Birmingham with the hometown Barons scoring two runs in the bottom of the ninth in their exciting 3-2 walk-off victory over Montgomery. The Alabamian landmark, which will become the oldest surviving professional baseball park in the country, is well attended by the citizens of the booming iron-and-steel town, often drawing standing-room-only crowds in excess of 10,000 fans in the first decade of it existence.
The Cubs stroke nine straight hits , that includes six singles, two doubles and a home run, off reliever Erskine Mayer in the top of the ninth inning at the Baker Bowl. Chicago's late offensive barrage produces six runs, helping the team to coast to an easy 10-4 victory over the Phillies. (Many sites erroneously list this game as being played on August 19, with Grover Alexander giving up the big inning.)
Boston defeats the Cardinals in their debut at Braves Field, 3-1. The concrete and steel facility, which took only five months to construct, becomes the first ballpark to seat more than 40,000 fans.
Jimmy Powers, sports editor of the Sunday New York Daily News, causes a flap when he suggests the Yankees' poor play this season can be attributed to "a mass polio epidemic" contracted from Lou Gehrig.

The Indians' streak of not giving up a run is extended to 30 innings when Sam Zoldak tosses a nine-hit shutout against St. Louis. Cleveland right-fielder Allie Clark scores all of the Tribe's runs in the 3-0 victory played at Cleveland Stadium.
In their 13-4 victory at Crosley Field, the Reds hit eight home runs (Bob Thurman  Ted Kluszewski  Frank Robinson  and Wally Post  ) to tie a major league mark. The Braves add two more to set a National League mark for total homers for a nine inning game.
Long time baseball executive Branch Rickey is named president of the newly formed Continental League. The 77 year-old former Dodger general manager is currently serving as an advisor with the Pittsburgh Pirates.
In a Midwest League contest, Bob Sprout throws a seven-inning no-hitter, striking out 22 batters as the Decatur Commodores defeat the Waterloo Hawks, 3–0. The 18 year-old minor league southpaw will pitch in just one big league game appearing with the Angels in 1961.
Lew Burdette pitches a no-hitter, beating Gene Conley and the Phillies at County Stadium, 1-0. The Braves right-hander hits Tony Gonzalez with a one-out, fifth-inning pitch, preventing perfection, but still faces the minimum 27 batters by getting Lee Walls to ground into a double play.
The game against Baltimore is delayed twice when Indians' starting pitcher Pedro Ramos is asked to change his uniform, with the right-hander complying to the request by first changing his shirt, then returning to the Memorial Stadium locker room for a different jersey and hat. The umpires suspect the Cleveland right-hander is doctoring the baseball.
After hitting a ball on top of the pavilion at Sportsman's Park, Braves outfielder Hank Aaron is denied a homer when Chris Pelekoudas calls him out. The home plate umpire's decision is influenced by Cardinal catcher Tim McCarver, who is jumping up and down, insisting the eventual home champion had stepped out of the batter's box.
Tony Conigliaro's left cheekbone is shattered by a fastball thrown by Angels' hurler Jack Hamilton. The 22 year-old Red Sox slugger will miss the rest of 1967 and all next year, and will never come close to the Hall of Fame potential displayed during his first three seasons.
After playing in 414 games and accumulating over 1500 career at-bats, Larry Bowa hits his first major league home run, an inside-the-park round-tripper at Veterans Stadium.

Earl Averill, Bucky Harris, Billy Herman, 'Judy' Johnson and Ralph Kiner are inducted into the Hall of Fame.
In a 6-5 victory at Veterans Stadium, Giants' first baseman Willie McCovey hits his 505th home run off Larry Christenson, establishing him as the National League all-time left-handed home run leader.

At the Astrodome, Pete Rose becomes the all-time leader in plate appearances when he steps up to the plate for the 13,941st time. The Phillies first baseman surpasses Cardinal legend Stan Musial, who had established the mark in 1963.
In the second longest game in franchise history, the Cubs lose to the Dodgers, 2-1. The Wrigley Field contest, which is played over two days, takes a Dusty Baker sacrifice fly and 21 innings to complete.
Bucky Dent replaces Dallas Green (5th place, 56-65) as the Yankee manager. It is the 17th time the team has changed skippers during George Steinbrenner's 17-year tenure as the club's owner.
The Orioles' Cal Ripken passes Steve Garvey for the third-longest consecutive games streak by playing in his 1,208th straight game.
With his third-inning single off Jim Clancy, Jerome Walton extends his consecutive-game hitting streak to 28 games in a 6-5 loss to Houston at the Astrodome. The 24 year-old freshman outfielder ties a modern Cubs' record established by Ron Santo in 1966.
In spite of a Braves' rally in the ninth, Tom Henke records his 300th career save when the Cardinals edge Atlanta, 4-3. The Kansas City native becomes the seventh pitcher in major league history to reach this milestone.
Greg Maddux wins his 200th career game as the Braves beat the Giants, 8-4. All of Atlanta's nine hits in the game were doubles.
After beating out a potential double play ball to prolong a five-run ninth inning rally which ties the game, Angel flycatcher Darin Erstad makes a 10th inning game-saving catch and follows it with a game-winning homer in the 11th to beat the Yankees, 9-8.
Tim Salmon becomes the franchise leader in home runs with his fourth-inning solo shot off Roger Clemens in the Angels' eventual 9-8 extra-inning victory over New York at Yankee Stadium. The Anaheim DH's 223rd career round-tripper surpasses the total of Brian Downing, who had established the Halo mark in 1990.
In a pregame ceremony, Tommy Agee is inducted posthumously into the Mets Hall of Fame. The Mets' center fielder (1968-72) is best remembered for his two great catches in Game 3 of the 1969 World Series.
The Spokane Indians (Texas Rangers) edge the Tri-City Dust Devils (Colorado Rockies) 2-1 in 23 innings. The Northwest League game, which lasted 6 hours, 37 minutes, was scoreless for 19 innings and suspended in a 1-1 tie in the 21st inning the previous night.
At Fenway Park, the Yankees beat the Red Sox in the night cap to complete a day-night doubleheader sweep. The 14-11 slugfest, in which the Al East Division rivals bang out a total of 34 hits, takes 4 hours and 45 minutes to play, making it the longest nine-inning game in big league history. A team scores in nine of the 18 half-innings.
Mike Lieberthal passes Red Dooin to become the Phillies’ all-time leader in games as a catcher. The former Philadelphia backstop, who caught 1,124 games from 1902-14, is given credit for being the first catcher to wear shinguards (1906) and as player-manager (1914) tried but failed to convince owner William Barker to buy three promising players from Baltimore’s International League franchise, which included a pitcher named Babe Ruth.
Jered Weaver, blanking the Mariners for seven innings at Angel Stadium, joins Whitey Ford (Yankees, 1950) to become only the second American League rookie to begin a career with nine straight victories as a starter. The 23 year-old Angel hurler will need to win his next four games to match mark established by Hooks Wiltse, who started his freshman season in 1904 with 13 consecutive wins.
Alfonso Soriano becomes the third player in big league history to compile four seasons of 30 homers and 30 stolen bases. With his second inning swipe of second base in a 6-4 victory over the Phillies, the Nationals outfielder joins Barry and Bobby Bonds in accomplishing the feat for the fourth time.
Micah Owings, with two home runs, a double and a single, compiles 11 total bases in the Diamondbacks' 12-6 victory over the Braves, the most for a hurler since Braves right-hander Jim Tobin had 12 with his three homers in 1942. In addition to driving in six runs and scoring four times, the Arizona rookie tosses seven innings of three-hit ball to win his sixth game of the season.
The front-running Braves acquire slugger Derrek Lee from the Cubs for three minor league pitchers. As a ten-year veteran, who had played at least five years with the same team, the 34 year-old first baseman rejected a trade to the Angels last month because he thought LA had too much of a deficit to make up in the AL West race.
Mike Jacobs becomes the first professional baseball player to be suspended for testing positive for human growth hormone. The 30 year-old Rockies minor league first baseman, who has played for the Mets, Marlins and and Royals, is handed a 50-game suspension for his involvement with HGH.
Adam Dunn becomes the 50th major leaguer to hit 400 career runs when he goes deep in the eighth inning with a two-run blast off Tim Collins in a White Sox loss to Kansas City at Kauffman Stadium.
