Greg Deichmann's power is what intrigued the A's so much ahead of the 2017 MLB Draft. The left-handed-hitting outfielder hit 19 homers as a junior at LSU and 11 the season before, prompting Oakland to grab him in the second round of the draft two years ago.
This year in the Arizona Fall League, Deichmann's power returned.
Deichmann, 24, led all of the AFL with nine home runs over 23 games for the Mesa Solar Sox. He hit .256 with a .347 on-base percentage and .634 slugging percentage, good for an impressive .982 on-base percentage.

While Deichmann has light-tower power, his first long ball of the fall that had just enough juice to clear the wall is what truly stood out to him.
"It was a cutter that I hit to left-center," Deichmann said to MiLB.com's Sam Dykstra. "It was a reminder to me that I'm locked in. When I can go the other way with authority, I know I'm right. And it also showed me that I can do that type of homer in this league."
Deichmann started off his minor league career strong, belting eight homers with a .915 OPS in 46 games at Class A Short Season Vermont after the A's selected him in 2017 draft, but took a tumble a year later. As he dealt with hand injuries, the powerful outfielder struggled mightily in the hitter-friendly California League.

Over 47 games with the Stockton Ports, Deichmann batted a lowly .199 with six homers.
"It wasn't until the offseason that I could get my swing right, and really, it wasn't even until spring training when I started to find it again," Deichmann said to Dykstra. "It was about three months of the year lost in Stockton, and I had to jump back into the spring at a full go without many at-bats (166), all broken up."

Despite the down year, the A's still promoted Deichmann to Double-A Midland last season. He didn't exactly dominate with a .219 batting average and .675 OPS, but Deichmann did play a career-high 80 games -- though he missed two months with a Grade 3 AC joint sprain -- and hit a career-high 11 homers.
A fully healthy Deichmann will be a name to watch next year as he showed in the AFL. His key is staying on the field, and when he does, get ready for a souvenir in the outfield bleachers.
