• 1:10 p.m. ET: The Nationals keep hovering in the NL wild-card race, and now they'll be running out their ace, Livan Hernandez, in the series finale against the Mets and Jae Seo, who is having a very strong season, at 7-2 and a 1.98 ERA.
• 2:10 p.m. ET: Mark Buehrle looks to pick up win No. 16, against the Kansas City Royals, and Zack Greinke looks to avoid loss No. 17. Mike Sweeney is The Most Likely Guy To Go Deep, because he has five homers in 48 career at-bats against Buehrle, with a .354 average. And with all logic pointing to a White Sox victory, the Royals are The Reverse Lock of the Day.
• 7:05 p.m. ET: Oakland's season is on the line this weekend in Boston, where the Red Sox almost never lose. Joe Blanton pitches the first game of this four-game set, The Must-Win Game of the Night, against Curt Schilling.
• 7:05 p.m. ET: The Phillies play the last game of their 10-game home stand, and could wrap it up with a sweep of the Atlanta Braves. Ace Brett Myers is on the mound against Jorge Sosa, who is coming off a strong start -- eight scoreless innings last weekend against the Nationals. This is The Must-Watch Game of the Night.
• 7:15 p.m. ET: The Yankees finish the season series with their archnemesis, the dreaded Tampa Bay Devil Rays, and they can be thankful they have their most effective pitcher, Aaron Small, on the mound. And let's just note that there are at least two very strange factoids in that previous sentence. Seth McClung pitches for the Devil Rays, and at the very least, he has the advantage of unfamiliarity working for him: The Yankees' roster has a total of nine career at-bats against McClung in the big leagues.
• 8:05 p.m. ET: This is the last chance for the Marlins and Astros to do battle in the wild-card head-to-head, and a couple of lefties go at it. The Young: Florida's Jason Vargas. The Old: Houston's Andy Pettitte. Florida is a half-game ahead of Houston and is tied with the Phillies.
• 10:05 p.m. ET: The Angels need some relief. They need some tonic. They need a victory. And lo and behold, their wish has been granted: They are set to begin a four-game set with Detroit, which has been averaging about one win a week lately. Bartolo Colon pitches against Mike Maroth.
