There was reason to be optimistic about the Diamondbacks' starting rotation before the season began. They added Eduardo Rodriguez, and in a surprise late coup, swooped in and snatched Jordan Montgomery on a short-term contract. Add the proven presences of Zac Gallen and Merrill Kelly, plus post-season breakout star Brandon Pfaadt, and things looked rosier for the rotation than for a very long time. Fangraphs projected them as the 8th-best set of starting pitchers in all baseball. That was an improvement of six places on the 2023 set, who reached the World Series - and was before the signing of Montgomery.
