There are three significant baseball milestones waiting to occur and all of them could happen tonight.  But regardless of whether any or all of them do come to pass, the most entertaining highlights may come from the stands rather than the field.

For starters, the Mets' Tom Glavine will go for career win No. 300 when he pitches against the Brewers in Milwaukee. He would be just the 23rd pitcher (and many believe perhaps the last) in major league history to reach that magic number.

The Yankee's Alex Rodriguez is on the cusp of hitting his 500th career home run and become the youngest player, 32, to join that exclusive club. The Yanks play the Chicago White Sox in the Bronx.

But the most notable impending event, of course, is Barry Bonds' attempt to tie Hank Aaron's all-time home run mark of No. 755.  With San Francisco on the road, Bonds will be contending with decidedly inhospitable crowds starting with Dodger Stadium tonight.  And such a circumstance means that fans will be exercising their imaginations as they express their indignity that Bonds -- obviously under the ever-present cloud of suspected steroids use -- is about to rewrite the record books.

For the next few days anyway, some of the most entertaining sports writing in the land may be done with crayons on cardboard.

For the record, commissioner Bud Selig will be there but Aaron will not.
