Not literally, but the Cardinals did take Cox with the 25th pick of the first round of Monday night's Major League Baseball Draft.
Asked when he found out, Cox - batting what would be a school record .427 with nine homers and 49 RBIs - said he had some help from the Arkansas fans in the middle of the contest.
"I guess when the people in the stands started yelling it at me from the dugout," Cox said after the game. "I came out of the game with a little rib injury and I heard people in the back (behind the dugout) yelling 'Cox is a Cardinal.'"
"Like I tell everybody, if I wanted to sign for money, I would have signed out of high school because I got enough money to where it was there - I would have been fine," Cox said. "But I just knew this (Arkansas) was a special place and I needed to come and add some things that would have limited me if I had went straight out of high school.
"I think coming here and learning from everybody and adjusting to the college game has been instrumental to what will hopefully be success in pro ball," Cox added.
Cox, who the Cards apparently will eye for both second and third base, thinks he has more options this time around when it comes to pro ball.
"If I had went straight out of high school, I probably would have went straight to the outfield," Cox said. "They probably wouldn't even have given me a chance to play third. I came here and I improved and hopefully I will get a chance to play third. Wherever I play, it doesn't really matter, but just adjusting to the pitching has been very key."
Although he knew the Cardinals were interested, Cox was also aware that he was projected as a top 10 pick.
"I had heard literally thousands of rumors going on," Cox said. "Just like anything else, I had to put that on the backburner and focus on playing. I still have a lot of unfinished business here at Arkansas. I have a lot of goals that I haven't accomplished yet. I want to win a national championship. There are a lot of things I want to do."
Arkansas head coach Dave Van Horn was obviously thrilled to have Cox around and now happy he is being rewarded for his patience.
"Zack turned down a lot of money to come here and he did us a big favor by coming," Van Horn said. "He has been fun to watch. I am looking forward to watching him in the big leagues in a couple of years."
He will get to see a possible future teammate in the Super Regional this weekend when the Razorbacks (43-19) take on No. 1 Arizona State (50-8).
That's because the Cardinals - who will be playing the Arizona Diamondbacks in Phoenix this weekend - also took Sun Devils pitcher Seth Blair (11-0, 3.20), the Pac-10 pitcher of the year.
"I haven't necessarily been a Cardinals fan, I grew up a White Sox fan, but I am a Cardinals fan now," Cox said.
As for not going in the top 10, Cox said "God has a plan."
The pick of Cox was met with praise from ESPN MLB insider Keith Law.
"Cox to STL – steal of the night so far," Law noted of a player who was projected by most to go in the top 10 picks.
It also drew praise from Cardinals vice president of amateur scouting and player development Jeff Luhnow, who was excited about taking the sophomore, draft eligible because he has turned 21.
"He's got a tremendous swing," Luhnow told Matthew Leach of StlCardinals.com "He's a baseball guy. He's been a baseball rat his entire life. He puts everything he has into the game, and it shows. He hit well over .400 this year in good competition. He hit well over .300 [in the Cape Cod League] this summer.
"This kid is going to probably be a fast mover through the Minor Leagues, because his bat is pretty close to being Major League-ready," Luhnow added. "We've seen him hit with wood. We've seen him hit with aluminum. We've seen him hit good pitching. He can hit a breaking ball. He can hit a fastball. There's not a lot this guy can't do with the bat."
Cox is "elite college bat" and the "best college bat in the country," Luhnow also noted St. Louis beat writers."
Cox "wants to sign," Luhnow also was quoted as saying. "We want to sign him. That's a good place to start."
Cox, who is trying to break the UA record batting average of .425 by Jeremy Jackson, was 2-for-3 during Monday's game before leaving with a sore back.
His two hits gave him a season total of 97, tying him with Matt Erickson's school record set in 1996.
Cox is battling a rib injury and has been for the last few weeks.
"It's not a bad injury, it is just in a bad spot," Cox said. "Every twist and turn you do in baseball, it kind of pinches a nerve on it. I don't think it is a serious injury, it is just something that I am going to have to battle and play through."
He had been the DH Saturday and Sunday, but asked to play in the field on Monday night - and then had to take himself out.
"It was fine hitting, but I felt like defensively I might hurt us out in the field because I couldn't move like I wanted to and throw like I wanted to," Cox said.
Van Horn knows his star has problems dialing it back a notch.
"It really doesn't bother him to swing, it bothers him to run," Van Horn said. "I told him to quit running so fast, slow down. But he flipped that ball down the left field line...and it's habit. He runs as hard as he could. He just bothers him when he starts running hard. He is breathing hard and just needs a few more days."
Arkansas signee Justin O'Conner was drafted 31st by the Tampa Bay Rays.
O'Conner is a pitcher/catcher that was the Indiana Gatorade Player of the Year and was doubtful to play because for the Razorbacks because of his likely high draft status.
He was ranked as the No. 29 high school senior prospect in the country by Baseball America.
