I agree that Grich and Sandberg are closer than most people think. But I think OPS+ does control for ballparks.
See this:

On-base Plus Slugging Plus (OPS+)
Definition
OPS+ takes a player's on-base plus slugging percentage and normalizes the number across the entire league. It accounts for external factors like ballparks. It then adjusts so a score of 100 is league average, and 150 is 50 percent better than the league average.
For example, Miguel Cabrera's .895 OPS in 2014 was 50 percent better than the MLB average after being adjusted for league and park factors. As a result, his OPS+ was 150.
The formula
100 x (OBP/lgOBP + SLG/lgSLG - 1)
Why it's useful:
OPS does not tell you how much a player was affected by factors such as his home ballpark's dimensions or altitude. OPS+ attempts to adjust for those factors to give you a context-neutral number.
