Editor's note: All stats are updated through Aug. 14.
By mid-August, the innings are piling up, and the arm is beginning to tire from hurling thousands of pitches. The sun shows no mercy for the pitcher laboring on the middle of the diamond.
Yet as the mercury rises, many pitchers are still able to reach back for something extra.
So who's been bringing the heat this summer? Check out which pitchers have been on fire since June 21, the first official day of summer (minimum of 40 innings pitched, except where indicated).
