In the above link regarding the DFA, it was noted that Hernandez wants to keep pitching:
Hernandez, who signed with the Braves after being released by the Astros in March, does not plan to retire. He had never previously worked as a reliever before signing with Atlanta.
Hernandez wasn’t great in his 19 relief appearances for the Braves, posting a 4.94 ERA and 1.548 WHIP in 31 innings, in which he allowed 40 hits. He wasn’t great last year as a starter for the Nationals, either; his 86 ERA+ was decidedly below average.
Yet, there are teams out there pretty desperate for starting pitching (hello, Blue Jays?), and so it seems likely that Livan Hernandez, who is (at least) 37 years old and who was a teammate of Andre Dawson when he made his MLB debut with the Marlins in 1996, will find work somewhere.
