Seattle Mariners Weather

For a few years now, T-Mobile Park has been the most pitcher-friendly park in all the bigs. Partially due to the constant humidity and marine layer at sea level, the ball just doesn't carry that well in Seattle. Toss in the fact that there's relatively less outfield real estate than most other parks, batters tend to overswing a bunch. Either way, it's always tough on batters in April and May. It plays a lot more fair at mid-season and the balance of summer.
