This is a case where looking at the overall numbers doesn't really indicate what's happening today. Sano's first ten games of the season: 46 PA, 16 SO, .237/.348/.711/1.058 Sano's 11-20th games of the season: 40 PA, 15 SO, .243/.300/.432/.732 Sano's 21-26th games of the season: 26 PA, 16 SO, .130/.231/.391/.622 That's not a slump, that's a massive hole in approach that is being exploited by pitchers.
