Here is the 2018 Opening Day roster for the Eugene Emeralds. The roster is provisional and subject to change.
The Emeralds first game is Friday night at home versus Vancouver (the Blue Jays affiliate in the Northwest League)
The short-season "A" teams that play in the NWL (and in the NYP League back east) have a 35-man Reserve List limit - AND - a 35-man Active List limit (with 25 players designated "active" for each game, of which ten must be pitchers). However, because players selected in last month's MLB First-Year Player Draft (Rule 4 Draft) and any Rule 4 draft-eligible player signed as a Non-Drafted Free-Agent (NDFA) after the draft do not count against a minor league reserve list until next November 20th, once the 2018 draft picks start getting assigned to Eugene, there will be players on the Emeralds' active list who are not on the reserve list and (presuming there are players on the Eugene DL) there will be players on the Emeralds' reserve list who are not on the active list, effectively creating a general roster that exceeds 35 players.
