Right-hander Yu Darvish will start Opening Day for the Texas Rangers against the Philadelphia Phillies, manager Ron Washington said.

Washington made that proclamation, as long as Darvish is healthy, after a fan asked about it at Rangers Fan Fest at Rangers Ballpark on Saturday.

"I think it's obvious," Washington said. "It's Darvish."

Darvish received an injection to relieve inflammation in his lower back after the season was over, but the club has received good reports and the 27-year-old is working out as normal this offseason in Japan, according to ESPN.com.

Darvish was 13-9 with a 2.83 ERA in 209 2/3 innings last season, and he led the league in fewest hits allowed per nine innings (6.22) and strikeouts (277).

Darvish was the runner-up in the AL Cy Young Award balloting last year.

Meanwhile, Rangers general manager Jon Daniels said the club will approach Darvish about a contract extension when the time is right.

"At some point, we'll sit down and talk with him just like we would on everybody," Daniels told ESPN.com. "He still has four years on his deal. I don't see a rush necessarily, but we'll address it at the right time.

"Right now, I'm focused on getting him in camp, getting him ready to make 33 starts this year."

According to ESPN.com, Darvish's contract has been a subject of conversation because of the seven-year, $155 million deal that fellow Japanese pitcher Masahiro Tanaka signed with the New York Yankees last week.

Darvish, who was posted under the old system after the 2011 season, received a six-year, $56 million contract -- with $4 million added if he's healthy in the final few years of the deal, according to ESPN.com -- after the Rangers paid $51.7 million to his Japanese team.
