Jorgensen, 26, a native of Kingwood, Texas, played in the Marlins' doubleheader at Colorado on Monday, starting Game 2 of the twin bill.
The Marlins promoted Jorgensen from triple-A Albuquerque on Sunday and optioned right-handed pitcher Randy Messenger to Albuquerque. To make room for Jorgensen on the 40-man roster, right-handed pitcher Logan Kensing, who was on the 15-day DL, was transferred to the 60-day DL.
Jorgensen appeared in 51 games with Albuquerque this season, batting .193 (26-for-135) with two home runs and 11 RBI. He was acquired by the Marlins in a six-player trade with the Chicago Cubs on March 27, 2002, that included Dontrelle Willis coming to the Marlins and Antonio Alfonseca and Matt Clement going to the Cubs.
Jorgensen helped lead LSU to the 2000 NCAA championship, appearing in 44 games (29 starts) behind the plate. He batted .302 (35-for-116) with 13 doubles, one triple, four homers and 23 RBI. Jorgensen also threw out 16 of 33 base runners attempting to steal.
Two other former Tigers made their major league debuts in 2005 – infielder Aaron Hill of the Toronto Blue Jays and infielder Mike Fontenot of the Chicago Cubs.
Other ex-LSU players who have seen MLB action this season include pitchers Paul Byrd (Los Angeles Angels), Russ Springer (Houston Astros), Randy Keisler (Cincinnati Reds) and Brian Tallet (Cleveland Indians); infielders Todd Walker (Chicago Cubs) and Russ Johnson (New York Yankees); and outfielders Brad Hawpe (Colorado Rockies) and Todd Linden (San Francisco Giants).
LSU has produced 50 major league baseball players in its history, including 36 since 1985.
