The Twins have retained Rule 5 pick Scott Diamond by working out a trade with the Braves, tweets MLB.com's Rhett Bollinger. The Twins are sending righty relief prospect Billy Bullock to the Braves in the deal. Diamond was assigned outright to Triple-A, according to the Twins.
Diamond, a 24-year-old southpaw, posted a 3.46 ERA, 7.0 K/9, 3.1 BB/9, and 0.3 HR/9 in 158 2/3 innings across 27 starts at Double and Triple-A last year. Baseball America ranked him 29th among Twins prospects, noting that his ceiling is as a fourth or fifth starter.
Bullock, 23, put up a 3.53 ERA, 12.8 K/9, 5.2 BB/9, and 0.6 HR/9 in 74 relief innings for the Twins' High-A and Double-A clubs last year. BA ranked Bullock 15th among Twins prospects, praising his repertoire but questioning his command. Having swapped their #15 prospect for their 29th best, the Twins clearly don't agree with Baseball America's rankings in this case.
