Quote:
Yahoo! Sports, citing sources, reported Wednesday that MLB will test a rule change in the rookie-level Gulf Coast League and the Arizona League this summer that will automatically place a runner on second base at the start of extra innings.
A similar rule has been used internationally and will be in place for next month's World Baseball Classic.
