The veteran lefty reliever, who signed a Minor League deal shortly before camp, moved the deadline of his opt-out clause from Friday to Saturday.
Though Reyes -- given his track record -- knows he will probably be on somebody's roster come Opening Day, he would like it to be the Red Sox.

"I don't know if it's going to make a difference or not, but they don't have the decision made yet," Reyes said. "They asked me for that extra day, and I said, 'Yeah.'"
There are two spots available in Boston's bullpen, and Reyes is competing with fellow lefties Hideki Okajima, Rich Hill and Andrew Miller, as well as righties Alfredo Aceves, Matt Albers and Scott Atchison.
"It's hard to tell," said Reyes. "You don't know what they're going to decide to do, but I think I'm putting myself in a position where I have a real chance. I did everything I could -- everything they asked me to do -- and I don't think I can do anything different or better than what I've been doing. Now, it's up to them and who they're going to take north."
Reyes is scheduled to pitch on Friday night against the Blue Jays. In eight Grapefruit League outings, Reyes has a 1.13 ERA. Over eight innings, he has registered eight strikeouts.
Even for a player who has been around as long as Reyes -- who will turn 34 on April 19 -- the unsettling final few days of camp uncertainty are tough.
"It's hard in the way that I want to play for a contending team, and I want to play for these guys," Reyes said. "These guys have a really good chance to get a shot in the playoffs and the World Series. That's one of the things I was looking for when I signed. Other than that, I want to play in the Major Leagues. If not here, then somewhere else."
In 669 Major League games, Reyes is 35-35 with a 4.18 ERA. He has pitched for the Dodgers, Reds, Rockies, Rangers, Pirates, D-backs, Royals, Padres, Twins and Cardinals.
