Made his professional debut with the United League champion Rio Grande Valley WhiteWings, playing in nine games down the stretch and batting .313 with a .538 on base percentage. In the TSL Latham was 6 for 18 with four RBIs and six runs, but was second in the league in triples (two) and hit by pitched balls (four) while striking out only once. At NAIA Bryan College Latham set eight career offensive records. All-time Lions leader in games (212), slugging (.574), hits (246), doubles (60), home runs (33), total bases (413), RBIs (173), hit by pitched balls (57), second in on-base percentage (.442) and multi-hit games (65), third in walks (78), and fourth all-time in batting average (.342), and runs (138).
