Prior to the start of the season the Astros acquired outfielder Billy Hatcher from the Cubs for Jerry Mumphrey. Lainer also made a change in the pitching staff, going with a three-man rotation to start the season. This allowed Lanier to keep his three starters (Nolan Ryan, Bob Knepper, and Mike Scott) sharp and to slowly work in rookie hurler Jim Deshaies. Bill Doran and Glenn Davis held down the right side of the field but Lainer rotated the left side. Denny Walling and Craig Reynolds faced the right-handed pitchers while Phil Garner and Dickie Thon batted against left-handers. Lainer knew the Astros had talent and he put it to work.
