His first inning homer came on a 95 mph fastball on a 1-2 count. The third inning shot also came on a 1-2 count, but off of a 97 mph fastball. Allen said he was simply trying to put the ball in play, but the velocity on the pitches he saw helped carry the ball over the fence.
"I was just trying to have a productive plate appearance and put a good swing on the ball," Allen said. "Fortunately enough, I was able to get a pitch I could do that with, and I'm definitely happy with the results."
Primarily known for his speed, Allen has 11 triples, 121 stolen bases and 14 home runs in 312 Minor League games. His two home runs were a case of an extremely rare power surge.
In fact, he had never had a multi-home run game in the Minor Leagues before Friday, and the last time he had a game like this was a long time ago.
"The last time was maybe way back in Little League," Allen said. "You definitely try to appreciate days like this where things tend to go your way. I'm just grateful for this opportunity."
The left fielder was not done contributing after his first two at-bats, tacking on an RBI single in the top of the fourth inning for his fourth RBI. It was Allen's first four-RBI performance as a professional.
He had an opportunity to knock in another run in the top of the sixth inning, but he struck out to end the inning. In the eighth inning, he stepped into the box with a runner on second base and two outs, but grounded out to the first baseman to finish 3-for-5.
Last season, Allen had a .298 batting average and a .424 on-base percentage with 38 stolen bases in 92 games with Class A Advanced Lynchburg before being called up to Double-A Akron.
With Akron, he hit .290 with a .399 on-base percentage with 13 extra-base hits and 13 RBIs over 37 games.
His approach has been impressive thus far in the Arizona Fall League as he sports a .361 batting average and is tied for the Solar Sox lead in home runs (two) and is third on the team in RBIs (seven).
