September call-ups aren’t what they used to be. MLB teams can add only two players to their active roster starting today, not the dozen or so — a lot of them rookies — that many used to bring up for the final month. That’s a shame in a way. A lot of careers were launched by young players who got a chance as a September addition. A handful of Mississippi products have debuted on Sept. 1 over the years. To wit: Luther Hackman, the big right-hander out of Columbus, started and went six innings, allowing five runs, for Colorado in 1999. The next year, former Mississippi State star Matt Ginter debuted for the Chicago White Sox with a scoreless inning. Nettleton’s Bill Hall got the call in 2002 from Milwaukee and went 0-for-1 as a pinch hitter. Fred Lewis, the Mississippi Gulf Coast Community College product from Hattiesburg, smacked an RBI double (off Rich Hill) as a pinch hitter for San Francisco. And in 2010, Itawamba CC alum Desmond Jennings started in center field and went 0-for-3 for Tampa Bay. … Among today’s call-ups is 31-year-old Billy Hamilton, the former Taylorsville High standout who was added by Minnesota. The Twins are the 11th different big league club he has signed with since 2018, his third this year. Hamilton, an intriguing September call-up by Cincinnati back in 2013, is a .239 career hitter, but he can steals bases — he’s the all-time Mississippi-born leader — and play center field with the best of ’em.
