In 2017 the Texas Rangers rewarded their second baseman with a large contract. He had finished a season batting .271 with 33 home runs and 88 RBIs.
Immediately his offensive production dropped. In 2017, although he hit 30 home runs, his batting average dropped to a career low of .204. The second season the average rose to .253 but the home runs dropped to 18. In years 3 and 4 his average plummeted to .205 and .167. Frustrated, the Rangers gave up and traded him to the Yankees. The trend continued with 15 home runs and a .202 average.
Five of the 6 seasons are complete; you can see the ship has been sinking the entire time.
