How the D-backs’ Season Fell Apart
On Sunday, the Rockies shut out the Diamondbacks 2-0, thus completing a three-game sweep in Arizona that put the home team out of its misery as far as the 2018 season is concerned. The Diamondbacks spent 125 days with at least a share of first place in the NL West this year, more than any other team, and when they weren’t in first they were at least in Wild Card contention. And then the calendar flipped to September, and they made like Wile E. Coyote:

From August 31 to September 23, the Diamondbacks lost 17 out of 22 games — that’s a half-game worse than the Orioles, who have already lost 111 games overall — producing a playoff odds graph that, as I suggested last week, looks more like the sharp spires of Utah’s Bryce Canyon than the signature expanses of Arizona’s Grand Canyon. (As a Utah native who has never hiked the latter, I may be biased here.)

Anyway, ouch. The collapse has to rate as one of the more gruesome in recent history, though it isn’t as though the team frittered away a seemingly insurmountable lead or was a powerhouse to begin with. The Diamondbacks’ largest lead in the NL West was six games, and that was as of May 1, when they had just beaten the Dodgers for the second straight night to open a four-game series and climbed to an NL-best 21-8. They have the NL’s fifth-worst record since then, despite outscoring the opposition:

That May 1 win was just one of eight the Diamondbacks notched that month en route to an 8-19 record. They rebounded to go 19-9 in June, but spent the next two months meandering around .500, going 13-13 in July and 14-12 in August. Even so, they were in either first or second place in the NL West for all but one day of that two-month span of mediocrity.
