Braves’ fireballer Brandon Beachy establishes the modern franchise record for strikeouts in a season by a rookie pitcher when he whiffs eight batters in 4.1 innings, bringing his to total to 160. Irv Young struck out 156 in 1905 when the team played in Boston and were known as the Beaneaters.

After missing fifty contests for a PED infraction in April 2008 while playing for the Giants, Eliezer Alfonzo becomes the first player to be suspended twice under the MLB drug program. The Colorado catcher will appeal the 100-game suspension, having the ban overturned for procedural reasons when his urine sample is not handled in the manner outlined in baseball’s agreement with the players.

Dillon Gee becomes the first Mets rookie to win 13 games in a season in 27 years when New York defeats Washington, 6-3. In 1984, Dwight Gooden compiled a 17-9 record as a freshman in 31 starts for the team.

In a pregame ceremony before a nationally televised game with Boston, the Yankees celebrate the 50th anniversary of Roger Maris’s record-breaking 61st home run. The festivities include New York captain Derek Jeter carrying to home plate the bat that the Rajah used to hit the Tracy Stallard pitch on October 1, 1961, and Sal Durante, the 19 year-old fan who caught the historic homer in the right field stands, bringing the ball onto the field.

It took him eight tries since he recorded his last win on July 24th, but 45-year-old Red Sox knuckleballer Tim Wakefield, the major leagues’ active win leader, finally records victory number 200. He pitches 6 innings and leaves with a 6 – 5 lead over the Blue Jays, then his teammates get to work padding that cushion, as the game ends 18 – 6. In the 9th inning, P Junichi Tazawa makes his return to the majors two years after an injury interrupted a promising major league debut.

Justin Verlander and the Detroit Tigers continue to steamroll over opponents. Verlander picks up his 23rd win – the first pitcher to reach that total since Barry Zito in 2002 – when he pitches 7 shutout innings over the White Sox, for a 5 – 0 win. Verlander has won his last 11 starts, something no one has done for the Bengals since Hal Newhouser in 1946. The win is also Detroit’s 11th straight this month.

After getting the first two outs on strikeouts, Mariano Rivera records his 600th career save when catcher Russell Martin throws out Ichiro Suzuki trying to steal second base for the final out of the game. The 41 year-old Yankee closer is one save shy of tying Trevor Hoffman’s major league career record.

2011 – The Diamondbacks continue to roll, defeating the Dodgers, 7 – 2, for their 17th win in their last 20 games. They are now tied with the Brewers for the second-best record in the National League. Joe Saunders picks up the win over Ted Lilly. J.J. Putz registers his 39th save in an excellent comeback season after Bryan Shaw loads the bases with two outs in the 9th.

The Mets’ request to wear caps honoring police, firefighters, and other first responders for their September 11th game against Chicago is denied by Major League Baseball. The hats, which were worn during the pregame ceremony of remembrance, will be autographed and sold on Mets.com, with the proceeds to be given to charities through the Mets’ foundation.
