As long as Andre Ethier continues to play regularly, he shouldn't have any problems extending his recently signed five-year, $85-million contract by another year.

Ethier's deal includes a $17.5-million team option for a sixth year, in 2018. If the Dodgers decline the option, they would owe him a $2.5-million buyout fee.

But the sixth year in the deal will become guaranteed if Ethier makes 550 plate appearances in 2017 or a combined 1,110 plate appearances in 2016 and 2017, according to people familiar with the contract. If the option is picked up or vests, the total value of the contract would increase to $100 million.

Ethier has made more than 550 plate appearances every season since becoming an everyday outfielder for the Dodgers in 2008.

Last season, he missed almost all of September to undergo a knee operation, but still finished with 551 plate appearances. When Ethier played in a career-high 160 games in 2009, he made 685 plate appearances.
