The Silver Slugger, like all baseball awards, likely doesn't go by any advanced metrics. So we're talking average, on base %, slugging, and dingers here. Certainly nothing more advanced than OPS. Historically, hitting lots of dingers and having high batting averages have been heavily favored. Dozier has the HR side covered, but Altuve looks more valuable as a hitter with his shiny batting average and higher OPS. As this is decided by voting, remember it's also a popularity contest. So if you plan to start a nasty rumor about Jose Altuve, now's the time.
