Indication of stealing signs?
Don Mattingly accused the Cardinals of stealing signs. He said that they have a system that uses the 3rd base coach. He pointed out that with RISP the Cardinals batting average was .330 while hitting only .236 with no runners on base. The Twins hit .247 with no runners on base.
Seems like it would have to be an elaborate system over a whole season in order to get away with this. If the Cards hit the NL average with RISP they would score 100 less runs.
Notice any sign stealing going around the league?
