53-25 projects to 110-52 over a full season, a near record pace which is remarkable when you consider that they get NOTHING out of right field, that Crawford hit about .200 for the first two months of the season and got injured once he started hitting, that they lost their shortstop Lowrie to injury, and every starting pitcher has missed starts, with one lost for the season and with most of us wishing another one was also. And Papelbon's ERA is still over 4 runs per 9 innings pitched!!
Among the pleasant surprises is the fact that the offensive output at catcher is actually somewhat above the league average, currently projecting to 20 homers, 80 RBI and 76 runs scored.
