Both of these events occurred on August 2, 1965.
Harmon Killebrew suffers a dislocated left elbow in a collision with Baltimore’s Russ Snyder in the 6th inning while playing first base at Met Stadium. The Twins slugger ends up missng 48 games. Killebrew was leading the AL in homers with 22 and RBI with 70.
Twins pitching Ace Camilo Pascual had surgery on his pitching arm in Washington D.C. and the surgery was deemed a success but how long he would be out was unknown. It turned out that Pascual missed 39 games and returned to the mound for the Twins on September 6. Pascual’s ailment was originally diagnosed as a possible tumor or Lipoma, a fatty growth but it turned out to be a torn muscle.
The Killebrew and Pascual articles are on page 18 and the recap of the Twins versus Orioles game can be found on page 19. Actually it is kind of fun to read the entire paper and read about the news back then and see some of the old ads.
