Arizona Diamondbacks Gameday Thread, #41: 5/12 @ Rangers

The last trip through the rotation for the Diamondbacks has been really good:

By that 5-game rolling average game score, it’s the best we’ve seen since a run around the All Star Break in 2022:

If we restrict to 5-game stretches with 5 different starters, it’s the best since September 2019:

So yeah, it’s been a while since we’ve had it this good. But this is still a far cry from the best in Diamondbacks history — the current stretch is only tied for 58th all-time. Here’s the best ever:

The good news is that there’s still quite a lot of room for Zac Gallen to improve on his last start, which had a Game Score of only 47. Doing so would give us an even better 5-game average. A score of better than 60 would surpass the 2022 streak; 69 or better would surpass 2018. Although it would take a career-best-tying 89 (reached against the Cubs on September 8, 2023) for him to pull the overall average into a tie for the franchise record. But any improvement on his last start would bring the rolling average up in the franchise rankings.
