Let’s clear out the notebook from this weekend’s disappointing series against the Twins:

* – The Red Sox have allowed two “go ahead” home runs while one strike from victory (i.e. leading in the game) this season. The other was Alex Avila’s two-run walk off shot given up by Mark Melancon in the 11th inning on April 8 in Detroit. Other than the two allowed by the Red Sox, there have only been two other such homers hit this season in major league baseball. There were no such home runs in the majors during all of last season.

Note this: Joe Mauer’s blast on Saturday was the first such homer this year when the hitter was on the road. Since 1988 (the first year that ball/strike counts were tracked), the Red Sox have now allowed four such home runs at Fenway, the most in the majors. Prior to Saturday, the last was given up by Keith Foulke in 2005.

Note this too: The last Twins player to hit such a dramatic home run was Kirby Puckett, who hit a 3-run walk off shot while down, 6-4, on a 2-2 count against Seattle in 1995.

* – On Sunday, Vicente Padilla became just the fifth Red Sox reliever ever to allow two home runs and not record an out, joining Mark Melancon (April 17), Manny Delcarmen (2009), Rob Murphy (1990), and Calvin Schiraldi (1987).

Note this: The Red Sox became just the ninth team to have two pitchers suffer such outings in the same season. Only one, the 2010 Cubs, have had three such relief outings in one year.

* – Through their first five August games, the Red Sox have allowed an inning of four or more runs in three of them and in 10 different games since the beginning of July. Only Cleveland (with 11) had more games allowing a big inning in that span. During the entire month of June, Boston allowed just one four run inning, tied for the fewest big innings allowed by any team in a single month (Dodgers in May and Giants in July).

* – Boston held Minnesota scoreless in the first inning on Sunday, extending their streak to six games without allowing a first inning run, tying their longest such streak of the season. Only two teams’ longest such streak this season is shorter than Boston’s: Colorado (4) and Minnesota (5).

Note this: Back in 2009, the Dodgers did not allow a first inning run in 30 consecutive games. They gave up one on July 30 and then another one on September 1. Over that entire 162-game season, the Dodgers allowed 54 first inning runs. Boston allowed 54 such runs this season in a 44-game stretch from June 10 through July 30.

* – From July 25 through Sunday, Red Sox relievers allowed eight home runs in 31 innings pitched. Prior to that, they allowed eight home runs in their previous 152 1/3 innings pitched (May 28 through July 24).

* – The Red Sox have now won five of the last six games in which Adrian Gonzalez has hit a home run, dating back to June 24. Prior to that, Boston had lost nine straight in which Gonzalez had homered (from last September 7 through June 8). That’s tied for the longest such streak in the majors since at least 2008.

Note this: In his career (since 2009), Arizona’s Gerardo Parra has homered in 21 different games. The Diamondbacks lost the first game in which he homered, and lost the most recent game in which he homered (June 19). In between, Arizona won all 19 games when Parra went yard.
