I am telling you now it DIDN"T in MLVB 15 they fixed it that year it did however in MLB 14 I have owned every MLB game the last 6 years and 14 and 16 are the only 2 years the CPU decides to steal bases on it's own
the trick is to hold L2 the entire at bat it stops the CPU from taking off at critical stages in the game and wasting outs, which btw base stealing this year is alot harder and 3 out of 4 times you seem to get caught, when in reality it should be 3 out of 4 times you can steal base as the leagues % is about 70%
