Looking at the team, there are several things to like about the 2013 Red Sox. Very good starting pitching, serviceable bullpen (which was was seriously depleted due to injuries before the all star break) with a hidden gem as a closer, a better than expected defense and a grinder offense.
Offensively the team is ranked 2nd in runs scored, rbi's, slugging percentage, etc. with the biggest stat of having taken 900 more pitches than the next team.
Looking at the schedule with 25 games left, if the Red Sox could win every series 2 out of 3, atleast split the 4 game series with the Yankees next weekend, they should not have a problem getting to 95 wins.
I don't think the Yankes will catch the Red Sox for the divisional crown, but after the mid september series in boston, their remaining series include: Toronto, San Fran, and Houston. I think that stretch right there might push the Yankees towards the 2nd wild card spot.
As for some talk on the boards about resting some of the players, in the month of September, there are 4 off days, with a projected clinching of the division on/around the Colorado series. I wouldn't rest the regulars until then.
