Throwing 44 pitches over three scoreless innings on Thursday, J.T. Ginn has taken the first official step of his pro career. The ex-Mississippi State standout from Brandon made his long-awaited debut for the Low-A St. Lucie Mets. He yielded two hits, two walks and an HBP while registering one strikeout against Fort Myers. It was Ginn’s first appearance in an actual game since February of 2020 with MSU. He had Tommy John surgery shortly thereafter. The New York Mets picked him in the second round of last summer’s draft; they figure to be very cautious this year with their No. 6-ranked prospect. At MSU, right-hander Ginn posted a 3.22 ERA and 109 strikeouts in 89 1/3 innings, most of those in 2019 when he was the SEC and national freshman of the year. He features power stuff: an upper 90s fastball, a nasty sinker and a hard slider. Elsewhere on minor league mounds: Former Southern Miss standout Kirk McCarty improved to 4-0 with a strong seven-inning outing for Triple-A Columbus in the Cleveland system. The 5-foot-8 lefty, who has a 4.04 ERA in six starts, allowed five hits and two runs with seven K’s to beat Indianapolis. He is in his fourth pro season. … Ole Miss product Chris Ellis saw his ERA jump to 9.26 in four starts for Triple-A Durham in Tampa Bay’s chain. The well-traveled Ellis, 28, was touched for two hits, two walks and two runs in just one inning; he escaped with a no-decision. Durham’s game against Norfolk was called in the eighth inning after Bulls pitcher Tyler Zombro was hit in the head by a line drive. He was hospitalized and in stable condition at last report.
