MLB and the MLBPA are making progress on a rule change for how players can slide into second base, according to ESPN's Buster Olney.
"Although the union wants to improve safety for middle infielders, it does not want to eliminate players' aggressiveness on slides or the ability to break up a double play," sources told Olney. "However, there is a desire on both sides to eliminate slides on which a baserunner goes beyond the effort to reach second to make contact with middle infielders."
In Game 2 of last year's NLDS, Dodgers 2B Chase Utley essentially tackled Ruben Tejada at second base in an effort to break up a potential double play. Utley was initially called out, but a replay review ruled him safe because Tejada never touched second base.
