Mark it down. Corey Dickerson, the former Meridian Community College star from McComb and Brookhaven Academy, belted his first career home run today for Colorado. He’ll hit more. He’s got serious thump — the left-handed hitting outfielder has 78 homers in his four minor league seasons — plus he gets to play home games in Coors Field, where the Rockies slugged four bombs today in a 6-5 win over Milwaukee. Dickerson was recalled for his second big league stint a couple of days ago when Colorado put former Ole Miss pitcher Drew Pomeranz on the disabled list. … Former Pillow Academy standout Louis Coleman has not allowed a run in 10 2/3 innings for resurgent Kansas City, now a .500 team. … Trade rumors continue to swirl about Meridian CC alum Cliff Lee, who was pulled from a scheduled start for fading Philadelphia on Saturday. Reports say St. Louis, Cleveland and Boston are among the most likely destinations for the veteran lefty, who is having a strong year (10-4, 3.05 ERA). … Isn’t it ironic that Atlanta finds itself looking for pitching help at a time when so many of its onetime prospects — and ex-Mississippi Braves standouts — are starting for other clubs: Randall Delgado in Arizona, Charlie Morton in Pittsburgh, Scott Diamond in Minnesota, Tommy Hanson in Anaheim and Todd Redmond in Toronto. (In addition, Matt Harrison is on the DL in Texas and Houston has plans to work Paul Clemens into its rotation soon.) … Ole Miss alum Bobby Wahl, picked in the fifth round by Oakland, has a 3.12 ERA in 8 2/3 innings of work in the low minors. The A’s are said to be very high on Wahl.
