A's propensity for scoring in the 9th Inning

Does anyone know if there's a site that shows team scoring by inning? I'm wondering what % of the A's runs come in the 9th and how that ranks against the rest of league. Additionally, are the A's most likely to score a run in the 9th versus any other inning? It seems like the A's score a fair amount of runs in the 9th inning. While these haven't translated to victories in most cases, these guys seem to play differently in the 9th than in any other inning; they seem more focused.
