The sender? Good friend and former teammate, Rays pitcher James Shields.
"If it was him, I'd feel the same way," Jackson said. "He's a good friend of mine and I would feel just as happy for him."
Jackson said he spent time with his parents for part of Friday night, following the record-breaking no-hit performance and then stayed out with friends "until around 3:30 a.m." Jackson said: "[I] got more sleep than I thought I would and woke up earlier than I thought I would.
"It was definitely a fun night, though, and well worth it."
Jackson, who did close to 15 separate interviews from Friday until Saturday, said the no-hitter still doesn't seem real.
"I watched a few highlights and it's all just surreal," Jackson said. "I'm just looking at it and saying, 'Really, really?'"
For Arizona shortstop Stephen Drew, who was on the other side of a no-hitter when the D-backs were held hitless by Florida's Anibal Sanchez on Sept. 6, 2006, it was special to play behind a teammate accomplishing the feat.
"It was one of those things where you don't really start thinking about it until it gets late in the game," said Drew, who ended the game with a throw to first on a grounder by the Rays' Jason Bartlett. "You just start positioning yourself in a way where hits can't get through. It was a special feeling to be a part of something like that."
Drew said he feels sore but "is OK" after twisting his left knee a bit on a single in the sixth inning of Friday's game.
"It's just sore and I'll just need to rest it a bit," said Drew, who wasn't in the lineup to start Saturday's game.
D-backs manager A.J. Hinch said that Drew has been "nursing a little bit of a sore knee" and "has been getting treatment" over the past week or so but should be fine.
"He's out of the lineup in favor of Tony [Abreu] more so because [Rays left-hander David Price] is pitching," Hinch said.
Hinch also said that catcher Miguel Montero has some back soreness and would rest a few days as well.
