OMG = One More Guy
I am guessing that it stands for One More Guy, who would be #11 on Mayo’s Top 10 list of Brewers Prospects.
Consider then, 2010, as his coming out party. Dykstra finished second in the organization with his .312 batting average. He also had a .416 on-base percentage while his 27 steals placed him fourth in the system. He got better as the season in the Midwest League wore on, too, hitting .329 with a .443 OBP and 19 steals in the second half of the season. He’s looking more and more like a sparkplug, top-of-the-order type.
