No, not only baseball. I also wager on ncaab, ncaaf, nfl, nba and NHL. I do post plays here and there but my bread and butter is baseball. I have done okay with these sports minus NHL and nba in making some money, but not with my own plays. I follow select guys I have come across here and there and with some plays my buddies are on. Still trying to figure out the NBA... very hard sport to cap imo. The books really try and throw you off with really crooked lines some days. Just have to be able to find them and then win them.
