The Marlins have acquired righty Andre Rienzo from the White Sox in exchange for lefty Dan Jennings, Miami announced.
Jennings, not to be confused with the Miami GM of the same name, owns a career 2.43 ERA with 7.6 K/9 and 4.0 BB/9 across the last three years. The left-hander will celebrate his 28th birthday not long after Opening Day.
Rienzo, 26, has made 21 starts and seven relief appearances for the White Sox over the last two years. In that time, he has posted a 5.89 ERA with 6.6 K/9 and 4.5 BB/9.
