More or less as expected in terms of positions. Daulton Varsho is in center field, and - albeit largely due to the lack of better alternatives - Drew Ellis is your starting third baseman. Seth Beer is the first DH for the Diamondbacks since that position became a permanent addition to games in National League parks. Ketel Marte is back at second base. And for the second Opening Day in a row, we don’t have Nick Ahmed at shortstop (Josh Rojas played there in the first game last year). This will be the third consecutive Opening Day where the team faces San Diego, and Arizona has also started off the season with a loss each of the past three seasons, their last win being a 2018 8-2 win over the Rockies.
