1st Sept. Record: 6-5 - Home: 5-3 - Road: 1-2
No transactions or birthdays to report, so instead, let's go back through the historical record for the month of September, and see how the team has done historically after the rosters expand.
Best September: 1999 (19-7). The team came in with a 7.5 game lead at the top of the NL West, and didn't let up the rest of the way, stretching it to 14 games by the end of September. Arizona blew the opposition away, averaging 6.2 runs per game, and three players posted an OPS over 1.000: Jay Bell (1.009), Steve Finley (1.095) and Erubiel Durazo, who produced a line of .352/.439/.676 for a 1.115 OPS. On pitching, Randy Johnson went 3-0 with a 2.61 ERA in his five starts, striking out 49 over 38 innings. But Brian Anderson finished stronger. after moving into the rotation mid-month, he had a 2.39 ERA, and that excludes five shutout innings in the last game of the year on Oct 3
Worst September: 2004 (8-19). No great surprise here, though that poor record was still 3.5 games better than the team managed in July. It was pitching that was the problem here, the team allowing five runs or more in fifteen of the 27 contests, but the Diamondbacks had a record of 2-18 when conceding over three. From Sept.2-4, the opposition scored 35 times in three games, a tally surpassed only once since (36, from Aug 22-24, 2005). An honorable mention in this category goes to 2009, when Arizona went 8-18 in September, the only other time they have won less than ten games in the month.
Last September: 2011 (16-9). In first by six at the end of August, there was still work to be done, not least because they played their nearest rivals, the Giants, six times, and the rest of the division in all but three games. The Diamondbacks got it done, going 5-1 versus San Francisco, to clinch the championship with five contests to spare. Miguel Montero and Aaron Hill led the offense, both men hitting over .300 for the month, Miggy also leading the team with 14 RBI. On the pitching side, Ian Kennedy went 4-0 with a 2.08 ERA, and J.J. Putz finished strong, with 11 scoreless appearances, and 10 saves in 10 opportunities.
