Doyle spent a little over a week on the free agent market. The right-hander was designated for assignment as the corresponding move when the Rockies acquired Cal Quantrill from the Guardians. Colorado non-tendered him directly from DFA limbo, meaning Doyle never landed on waivers (as is otherwise the case for players who are DFA and not traded).
That sent him to free agency for the first time. A third-round pick of Colorado in 2017, Doyle made a very brief MLB debut at the end of the shortened season. The Rox outrighted him from the 40-man roster a year later but reselected his contract this past July.
The Virginia product logged his most extensive major league action out of the Rox’s bullpen in the second half. He appeared in 15 games, working 23 2/3 innings. Doyle struggled to a 6.85 ERA with a subpar 17.5% strikeout percentage and a hefty 12.6% walk rate. Things were much better in Triple-A, where he turned in a 3.41 ERA over 37 innings despite working in a brutal home environment for pitchers in Albuquerque. Doyle punched out a solid 26.6% of batters faced at the top minor league level, albeit with a still concerning 11.7% walk rate.
There aren’t likely to be many season-opening opportunities in the Atlanta bullpen. The Braves have spots committed to Raisel Iglesias, A.J. Minter, Joe Jiménez, Pierce Johnson, Reynaldo López, Tyler Matzek and Aaron Bummer. Even if López works out of the starting rotation, as the organization has suggested is possible, there’d only be around two vacancies available if everyone is healthy. Dylan Lee or Daysbel Hernández could have first crack at those jobs. Doyle figures to open the year at Triple-A Gwinnett as a depth option.
