Making the final preparations for what will be his 20th Major League season, Colon scattered four hits and two earned runs over three innings. The 43-year-old right-hander surrendered consecutive singles to Gary Sanchez and Bird in the first inning, then retired eight straight before Sanchez doubled ahead of Bird's homer.
Pineda allowed three runs and six hits over five innings before the Braves constructed their decisive sixth against Dellin Betances and Jonathan Holder, who combined to allow five unearned runs.
Betances allowed two-out singles to the only batters he faced -- Brandon Phillips and Adonis Garcia -- and Holder issued a pair of walks before surrendering Jace Peterson's three-run double, a hit that eluded Dustin Fowler in shallow center field.
