Baseball America has learned that two prospects on the High School Top 100 (subscriber-only) list have suffered injuries recently that will require surgery. Outfielder/lefthander Slade Heathcott of Texas High in Texarkana, Texas, was injured in a football game in October and had surgery for a torn anterior cruciate ligament in his left knee. Dr. James Andrews in Birmingham, Ala., performed the procedure Tuesday, according to Louisiana State, to whom Heathcott has committed. Outfielder Todd Glaesmann of Midway High in Hewitt, Texas, was also injured playing football. He’s expected to have surgery on his ulnar collateral ligament in his left thumb.

Heathcott, No. 28 on the High School Top 100, brings pure athleticism to the field and hits for both average and power. He stands at 6-foot-2, 190 pounds. On the mound he works with an 88-91 mph fastball and mixes in a curveball and changeup. Heathcott also wound up at No. 45 on our overall Top 100 for the 2009 draft.

Glaesmann, No. 55 on High School Top 100, is a righthanded-hitting corner outfielder. His father confirmed in a phone call that Glaesmann tore a ligament in his thumb and would have surgery after the football season. He is still playing football and has his thumb wrapped in tape for each game. He is a quarterback and wide receiver, but the injury is on his non-throwing hand. After the surgery, Glaesmann is expected to be in a cast for six weeks, and then rehab could take up to another six weeks. He has also swung a bat recently with the injury and has felt comfortable without any pain.

Glaesmann has a loose, projectable, 6-foot-4, 200-pound frame. Committed to Texas A&M, Glaesmann shows a strong arm, but could benefit from a higher arm slot. He has an impressive natural swing that needs to be a little shorter, but adjustments could turn him into a very good hitting prospect. Glaesmann checked in at No. 100 on the overall Top 100.
