Houston Astros second baseman Jose Altuve batted .485 (48-for-99) in the month of July. Of all batters with a minimum of 80 at-bats in the month of July in in a season in MLB history, Altuve’s .485 average is the sixth highest all-time. The others: Ty Cobb (.521 in 1918), George Brett (.494 in 1980), Ty Cobb (.489 in 1922), Tris Speaker (.489 in 1923) and Rogers Hornsby (.488 in 1923).
Since 2000, there have been six players (now seven with Altuve) who batted .430 or above in the month of July (again, minimum of 80 at-bats in the month to qualify for the list). The six:
Andrew McCutcheon (.446 in 2012)
Larry Walker (.438 in 2002)
Johnny Damon (.436 in 2000)
Gerardo Parra (.435 in 2015)
Delmon Young (.434 in 2010)
Ichiro Suzuki (.432 in 2004)
A quick note about Parra… he hit .435 in July, 2015 with the Brewers. After finishing with that average for the month, he was promptly traded on August 1 to the Baltimore Orioles for current Brewers pitcher Zach Davies.
