Here are the most compelling matchups, stories, and personalities in Major League Baseball for the coming weekend.

10. Reality Cometh for One (BAL-CLE)

Now for this weekend’s metaphorical boxing match between two of the luckiest teams in baseball. In one corner, we have the Baltimore Orioles — 48-44, in a really good division, with a run differential of -55. In this corner, you've got the Cleveland Indians, standing 47-45 in a pretty good division, with a run differential of -36. Stick with me while I analyze these teams with some complex baseball terminology: They are total flukes. In games decided by two runs or less, the Orioles are 32-14 (first in baseball), and the Indians are 25-16 (good for fourth). But do they have great starting pitching? Nope. Do they have great bullpen pitching? Baltimore is pretty solid, but Cleveland is near the bottom. What about run-scoring from the seventh inning on? Again, average to below average for both. Average with RISP and two outs? Mediocre. All this means that both teams have been very, very lucky to stay above, and that both are due for bad times. If you get excited by regression, then you'll be riveted by this series, where cold, hard, statistical truth will dig its icy claws into temporary luck.

In case you were out living a life of leisure, here's what you missed in sports over the weekend.

• Sources report that the NFL Players Association had the tapes of Gregg Williams's violent bounty speech before they became public. Instead of outing him publicly for targeting players, though, the NFLPA used the audio to make two sick techno tracks: "Kill the Head and the Body Will Die," and "A Mind Troubled by Doubt." Both tracks are scheduled to be released by NFL Films in mid-August on the album Bounty Sheriff.
