Smoak had nothing to turn around, though, is the point. From the beginning of the season (March 29th) until June 3rd, he put up a 136 wRC+. From June 5th until June 27th, he put up a futile 47 wRC+. However, since June 29th, he's contributed a 210 wRC+ (not including tonight's assault).
For almost the entire season, minus one awful stretch that lasted for only three weeks, Smoak's been well above average. He is especially hot right now, though.
