MLB.com and others are all saying Mazzaro starts for the Royals tonight, but Betfair have Mendoza down.
Do they ever change these (when the lineups are confirmed, perhaps?) or do they just let the markets run and then void every bet anyway. Does this happen often on here? Frustrating as I fancy TEX on the -1.5 against Mazzaro tonight, but no point putting the bet down with the market as it is.
