Farrell made the decision to go with Porcello, last season's American League Cy Young Award winner, before Price sustained a left forearm injury that is all but certain to keep him off the 25-man roster for the start of the season.
"Yeah, I mean, those guys are incredible starting pitchers," said Porcello, who will face the Pirates on April 3 at Fenway Park. "To get the ball, I don't think it's slighting them or anything like that. It's a huge honor to have it. I think it's tradition for the pitchers, when you get the ball Opening Day, it tends to be a big deal. So I'm grateful for that opportunity and it's definitely an honor, especially with the talented rotation that we have."
Porcello earned the honor by having a breakthrough season in 2016, going 22-4 with a 3.15 ERA.
"I'm treating like I'm going to treat my other hopefully 33, 34 or however many starts it is," Porcello said. "You know it's Game 1, I've got Pittsburgh and I'll be ready to go. It's not anything different. I don't think it would make sense to put more emphasis on your first start of the year as opposed to your 10th or 15th. I'm going to prepare like I always do and take everything in stride, and do what I know how to do."
