At the start of the 2016 season, Davis was rewarded for his power production with a 7 year $161 million contract. What followed was a historic level of offensive failure. It started fine in 2016 with minor drop offs. He hit 38 home runs with 84 RBIs. The batting average dropped to .221 with 219 strikeouts. He has never hit over 30 home runs again. 2017, he hit 26 home runs with 61 RBIs. His batting average was .215 and he struck out 195 times at a rate of 37.2% of the time.
In the following three years he has never batted higher than .179. HIs home runs dropped to 16, 12 and 0 in the shortened 2020 season. Strikeouts have stayed very high and his OBP has crashed to .243, .276 and finally .164. In 2018 and 2019, Davis set a major league record by batting 54 consecutive times without a hit. His production collapsed so drastically that in 2020, he only played in 16 games with no home runs and 1 RBI. In 2021, Davis was put on the 60 day disabled list with a lower back strain. On May 19, it was announced that he would miss the whole season.
On August 12, 2021, he announced his retirement. Five seasons: he averaged 152 strikeouts per year for $161 million.
