Bott, a 22-year-old left-hander, was 7-7 with a 3.16 ERA, and a remarkable 143 strikeouts and only 38 walks last year at Single-A. He will report to the Dodgers' Double-A Jacksonville club.
Looper, a 27-year-old right-hander, was designated for assignment the day after his acquisition because the Dodgers needed a spot on the 40-man roster for outfielder Milton Bradley.
The club had 10 days in which to trade Looper, release him or place him on waivers with the intent of outrighting him to the minor leagues.
