O'Day had his contract selected by Atlanta on Sunday.

EDGE Analysis

The 39-year-old was in camp as a non-roster invitee, and he apparently showed enough to warrant Atlanta adding him to the 40-man roster ahead of Opening Day. O'Day had a 3.38 ERA, 1.22 WHIP and 11:4 K:BB over 10.2 innings last year and should operate in middle relief.
