Dylan Carlson led off two innings on Wednesday night and homered both times.
The second-ranked Cardinals prospect went 3-for-4 with a pair of solo dingers -- his first career multi-homer effort -- in Double-A Springfield's 5-2 win over Amarillo at Hodgetown.

The switch-hitting right fielder opened the game against Sod Poodles left-hander Nick Margevicius, who made 12 big league starts this season, and sent a line drive off the batter's eye in center field for his 15th homer of the season.
Batting second in the third inning, Carlson lined a 2-2 pitch to center for a single. Leading off the fifth, MLB.com's No. 88 overall prospect sent a 1-1 offering just to the right of dead center for another solo shot. Margevicius finally retired Carlson in the seventh, when he grounded sharply to second.

"It's definitely been a buildup," he told MiLB.com's Sam Dykstra. "It's been a process all throughout the Minors. I'm real grateful for all the struggles I've had because I don't think I would be here without them."
