McCann's double tied the game after Bo Bigham, Tim Carver and Zack Cox all reached with no outs in the inning and the Black clinging to a 3-1 lead. Following a Matt Vinson groundout to first, McKinney cleared the bases with a blast over the 375-foot mark in left field to give the Cardinal a 6-3 lead.
"I think it came down to the bullpens and obviously the red team got hot and got a couple of big hits," Arkansas coach Dave Van Horn said. "They took advantage of a walk and a hit batter, and a two-strike single by Bo Bigham led off the inning. McKinney got ahead of the count and hit a missile out of the park and hit a no-doubter.
"It'd been a pretty boring game there for a while. The best part of the game early was the defensive play. There were some super plays; Bo Bigham made a big play up the middle and (Brett) Eibner made a nice diving play. The pitchers got after them a little bit and to see the offense bust through late like that was good."
Arkansas Black pulled within 6-4 in the bottom half of the eighth inning on a solo home run by freshman infielder Derrick Bleeker – his second in as many games.
But McCann put the game out of reach with his second 2-RBI double in as many innings to put the Cardinal team up 8-4 in the top of the ninth. McCann, who would later score on a double steal, finished the game 2-for-5 with four RBIs and two runs scored.
"He's really improved offensively," Van Horn said. "One of the biggest improvements on the team as far as individually has been his change at the plate. We saw that from day one (of fall camp). He drove in four runs today and got a couple of big hits and that's really going to help us come spring."
The Black team had taken an early 2-1 lead on a 2-RBI double by Travis Sample in the bottom of the first inning to counter a Bigham run in the top half of the inning. It was Sample's fourth RBI in two games in the series.
Zack Hall (1-0) picked up the win for the Cardinal team while Trent Daniel (0-1) was tagged with the loss. Daniel took the mound with the lead entering the eighth inning before giving up five runs – all earned.
Potential weekend starters Mike Bolsinger (Cardinal) and Drew Smyly (Black) got the starting nods with limited pitch counts. Bolsinger finished with four innings pitched, allowing two runs on three hits and struck out six batters.
Smyly went 3.1 innings, allowing one run on four hits and a walk, while striking out five. He was in line to get the win before the Cardinal rally.
"They did a good job," Van Horn said of his starters. "I thought Smyly worked quick and did a great job. I thought Bolsinger had good stuff but he needed to pick up the pace a little bit. He's fighting a little bit of a knee problem right now that's kind of bothering him, but they both threw well."
The series continues Sunday with a first pitch scheduled for 2 p.m. Freshman right-hander DJ Baxendale will get the start on the mound for the Black team while junior right-hander Sam Murphy will start for the Cardinal team.
"It's a pretty close series," Van Horn said. "It's tight and we're for sure going to go at least four; I like that. I hope it goes five to be honest."
