Manager Dave Roberts said Sunday that Anderson will likely begin the season as a piggyback bulk arm when needed, Fabian Ardaya of The Athletic reports.

Anderson was in the mix for a starting role during spring training, but it appears as though Tony Gonsolin will win the team's fifth rotation spot while Andrew Heaney serves as a fill-in starter with Trevor Bauer (not injury related) on administrative leave. Anderson served exclusively as a starter with the Pirates and Mariners last year and posted a 4.53 ERA and 1.25 WHIP in 167 innings. However, his fantasy value will take a hit if he ultimately serves as a long reliever this year.
