There really aren't many cheap doubles in this game, most are obviously hit hard. BABIP accounts for doubles and triples putting too much emphasis on where the defense isn't compared to how hard he hit the ball, that's my beef with BABIP. '05 was a fluke year as well for HRs, of course you're using HRs in the discussions of BABIP. SLG% doesn't isolate singles or HRs from DBs and TRs. I'm more likely to consider a single not dependent on how hard a batter hit a ball compared to where he placed the single. I can't say the same thing for doubles, obviously no matter how hard you hit the ball, many times it will be hit at someone. But, over time the odds will favor the skill of a hitter (higher line drive %) compared to the essence of using BABIP (luck). If a hitter has similar BB/K, HR, and single ratios but the jump in his BABIP was caused by XBHs while having a higher LD%, I'm more inclined to use luck (BABIP) as the reason compared to he just hit the ball better than he ever had. That doesn't equate to him being able to do so again as well as him not being the answer to the Cubs 2 biggest problems on offense with limited chances to improve it.
