Yamamoto, Helen #74

Taking over the title from Katie Clayton as worst pitcher ever, Yamamoto set record-worsts in pitching for the Daly City team – she packed a 9.35 ERA and 2.54 WHIP, and even worse, had a components ERA of 12.05. Despite this, she still pitched a substantial 26 innings of work, raising the team’s ERA from 2.83 to 2.94 all on her own.

In 2005, Yamamoto set records as the worst pitcher in the history of Daly City baseball. Her 9.35 ERA, 2.54 WHIP, 12.05 CERA, all set records, besting former mopup reliever Katie Clayton. In 2006 Yamamoto was better, but still not quite good enough – she improved her numbers to 6.00 ERA, 1.96 WHIP, and 7.14 CERA, once again worst on the team. Yamamoto did show signs of improvement during the season, however – through the month of June she had put together a spectacular stretch which chiseled her ERA down just under the 3.00 mark. From there, Yamamoto suffered perhaps one of the worst meltdowns in history, putting up ERA marks of 7.36, 11.57, and 11.25 in the following months, before a 1-appearance, 13.51 ERA, 6.00 WHIP performance in the playoffs.
