Khris Davis didn’t do anything different this winter. No new workout routine, no new diet.

“No, no, no, why would I change anything up?” the A’s DH said. “Come on! I’m at the top of my game right now. I wouldn’t change that up!”

Davis is a model of consistency. He has hit 42 or more homers in each of his three seasons with Oakland, including a major-league high 48 last year. And then there’s that batting average. He’s hit .247 four years in a row. He’s the first player ever to hit for the same average three years in a row, much less four.

“I like it - I did it to myself,” he said with a laugh. “I’m the only one who can hit .247 for four years. I pretty much have that force field around me.”

The one thing hanging over Davis’ head this season is his contract. The A’s have been talking about a long-term deal with him for more than a year, but nothing has yet to materialize. He will make $16.5 million this year, his final year of arbitration, and the team is more than likely to give him a qualifying offer after this season if he’s healthy. He’d assuredly accept because the figure should be over $18 million, so Davis is looking for at least a three-year deal with the A’s, as The Chronicle has previously reported.
