There appear to be two marquee series this weekend. In a three-game set beginning late this afternoon, Tennessee (No. 3/5 in the two national polls) visits Florida (4/6). The Saturday and Sunday games will be televised on the ESPN family of networks.
Over in Columbia, Missouri, No. 8/9 Mizzou hosts No. 3/4 Texas in a two-game series, Saturday and Sunday. The latter game will be on ESPN.
In most years, a three-game series between Arizona and UCLA would qualify as "marquee." This year, however, both teams have fallen out of the Top 10, so the Friday-through-Sunday series in Westwood can probably best be seen as an opportunity for one of the teams to jump-start its season.
Other Pac 10 series include: No.1 Arizona State at Washington, Cal at Oregon State, and Stanford at Oregon. All six of these teams, except Oregon State, are nationally ranked.
