Rob Whalen

Drafted in the 12th round of the 2012 draft, Whalen spent the first four years of his career with the Mets' Rookie and Single-A affiliates before being traded to the Braves in 2015. He features a fastball that sits in the low 90s and a hard-moving slider that generates a fair amount of groundballs. He spent the first four months of 2016 between Double-A Mississippi and Triple-A Gwinnett where he posted a combined 2.40 ERA, 1,19 WHIP and 112:44 K:BB over 21 starts. He joined the Braves' starting rotation in August and made five starts before being shut down with a shoulder injury. In his five starts, the rookie posted a 6.57 ERA and 25:12 K:BB over 24.2 innings. He was likely due for some positive regression, as he held a low 51 percent strand rate. Traded to Seattle for first-round pick Alex Jackson in November, Whalen has a chance to make the major league roster as a bullpen arm or emergency starter in 2017.
