Where were these races? And are there any times posted for them?
Sorry for the delay, I was away this weekend.
Anyway, the first two year old to win in 1911 was 'Royal Tea', who ran 3f in .36 at Juarez, Mexico. That was the beginning of a busy year for Royal Tea - he went on to make twenty-seven starts in 1911, winning eight of them. I don't have lifetime charts for him (there's a gap in my resource material between 1911 -1920
The next day at Moncrief Park in Jacksonville, FL, 'Colonel Cook' ran 2f in .23 2/5. He won four of twenty-one races at two. Can't find anything further on him.
The New California Jockey Club meet at Oakland also was offering baby races that January, at 3f. The appropriately named 'Oakland' won the first on those on Jan. 2, setting a new track record of .34 4/5 ('cantering', according to the chart). He made a measly 14 starts at two, winning six, but again, I don't have anything for him beyond that.
