Arroyo, 38, is recovering from Tommy John surgery last July. The operation shortened his first season with the Diamondbacks to 14 starts, as Arroyo went 7–4 with a 4.08 ERA. He had signed a two-year contract worth $23.5 million with Arizona, including a $9.5 million buyout for this season and a $4.5 million buyout for 2016.
Arroyo, who was on the Diamondbacks’ 60-day disabled list, was one of the more durable pitches in baseball before the surgery; in every season from 2005 to 2013, he made at least 32 starts and pitched at least 199 innings.
An All-Star in 2006, Arroyo has posted a career 145–131 record with a 4.19 ERA over 15 seasons.
The Braves also acquired minor-league prospect, righthander Touki Toussaint. The pitcher, who turned 19 on Saturday, was the Diamondbacks’ first-round draft pick in 2014 and was the franchise’s No. 5 prospect according to Baseball America.
In exchange for Arroyo and Toussaint, the Diamondbacks received infielder Phil Gosselin. The 26-year-old Gosselin batted .325 with two RBIs and two runs scored over 20 games before having thumb surgery in May. He is expected to return before the All-Star break.
