Steven mentions that his sister Hayley was giving the coach a Rod Carew in the parking lot. Rod Carew was a Major League Baseball player for the Minnesota Twins and California Angels in the 1970s and 1980s. In addition to being the only major leaguer to ever be born in a train, he was one of the most prolific hitters of his generation. It should be noted that Steve is using R"od Carew" as rhyming slang for "screw".
That'd be kinda funny, but would those OTHER characters even recognize each other? She didn't do much beyond working the case of the dead girls at the dock and messing around with McNulty and the kids at home.
