Prince Fielder’s NL-leading 46th home run establishes a Brewers franchise record. The Milwaukee first baseman’s third inning round-tripper off Reds’ hurler Kirk Saarloos breaks the team’s home-run mark set by Gorman Thomas (1979) and Richie Sexson (2001, 2003).

Although it’s nowhere near the amount 1998’s Mark McGwire’s single season home run record ball commanded, Giants slugger Barry Bonds’ career No. 756 home run baseball sells for more than experts predicted. The ball thrown by Nationals pitcher Mike Bacsik on August 7, which was auctioned by Matt Murphy, the fan who caught the historic homer, is won by an unidentified bidder for $752,467.

Ten year-old Bosox fan Griffin Whitman is disappointed when Yankees outfielder Shelley Duncan, when asked for an autograph, writes in the boy’s spiral-bound notebook, “RED SOX SUCK!” before signing his name. The 27 year-old flychaser, whose dad is the respected pitching coach of the Cardinals, is surprised by the negative reaction of the family.

After 13 years on the job, Terry Ryan announces his resignation as Twins general manager will be effective at the end of the month. The 53 year-old, who will serve as the team’s senior advisor to the GM, saw his team win the AL Central last season for the fourth time since 2001.

At Safeco Field, A’s backstop Kurt Suzuki and DH Dan Johnson both hit grand slams in the team’s 9-3 victory over Seattle. The Oakland catcher’s bases-loaded homer comes in the top off the second inning off Horacio Ramirez, with his teammate accomplishing the same feat with two outs in the ninth off Ryan Rowland-Smith.

2007 – Troy Tulowitzki homers off of Kyle Lohse. It is his 20th home run of the season and gives him the record for National League rookie shortstops. Ernie Banks had held the record with 19 for 53 years.

Hitting his 20th home run of the season, Troy Tulowitzki of the Rockies breaks Ernie Banks’ National League rookie record for most home runs by a shortstop in a single season. The Cubs Hall of Famer, who compiled a total of 512 homers, hit 19 dingers as a freshman in 1954.

Todd Helton hits his 35th double of the season, this one against Joe Thatcher, in a 4 – 2 Rockies win. It makes him the first major leaguer ever to hit 35 or more doubles 10 years in a row; even the legendary Tris Speakerhad only had 9 such seasons in a row.

In the first inning at Detroit’s Comerica Park, Curtis Granderson steals his 20th base of the season to become only the third major leaguer to belong to the 20-20-20-20 club. The Tigers center fielder joins Frank Schulte (1911 – Cubs) and Willie Mays (1957 – Giants) as the only players to record 20 home runs, 20 triples, and 20 doubles, as well as swiping 20 bases in a season.

2007 – Alex Rodriguez continues to lead the Yankees in their playoff hopes. He homers twice off Brian Bannister. The first of the homers is his 49th of the year and breaks the record for homers by a third baseman. Previously, Mike Schmidt (48 in 1980) and Rodriguez (2005) had shared the record. The Yankees win, 11 – 5. Rodriguez already holds the single-season record for shortstops, giving him the highwater mark at two positions.
