Wild card showdown, part 3: Have you heard the Rays are pressing the Red Sox for the American League wild card? And they're playing each other right now? Oh, maybe you have. Yeah, it's been covered to death, it seems, but it's still as big of a series as there is right now. Boston's win on Friday means the Rays won't leave town any closer than two games behind the Red Sox. Lefty Jon Lester takes the mound for the Red Sox, and with another victory, Boston could exhale -- at least a little. Lester was roughed up by the Rays in his last outing, as Tampa Bay recorded eight hits and four runs against him in just four innings of work. That broke a streak of five starts of allowing just one earned run or less. He's 1-2 with a 4.00 ERA in three starts against the Rays this season. Tampa Bay's Jeff Niemann's only faced the Red Sox once this season, allowing just two hits in eight shutout innings while striking out 10 on July 17. However, the Red Sox won that game, 1-0. Rays at Red Sox, 4:10 p.m. ET
Division title in sight: Both the Cardinals and the Phillies are still alive in the playoff hunt, but while the Cardinals need a lot of help, the Phillies have already clinched a playoff berth and with a win would clinch the National League East title. Of course, with a magic number of one, the Phillies could clinch the division before Roy Oswalt makes a pitch if the Braves lose their 4:10 pm. game against R.A. Dickey and the Mets at Turner Field. The Cards would welcome that as St. Louis trails Atlanta by just 3.5 games in the National League wild card race. Cardinals at Phillies, 7:05 p.m. ET
Strasmas time again: With a combined 138-160 record, there would normally be very little reason to take notice of a September game between the Marlins and Nationals. But this isn't just any game, it's a Strasmas outing, as Stephen Strasburg makes his third start of the season. In eight total innings this season, Strasburg has allowed one run and struck out eight, allowing five hits. He has not walked a batter yet. Strasburg's last start went just three innings after throwing 31 pitches. With an extra day of rest, hopefully we'll get to see him go a little longer this time. He's scheduled to make at least one more start -- Sept. 23 against Atlanta -- and could pitch in the Nationals' last game of the season, Sept. 28 at Florida. Marlins at Nationals, 7:05 p.m. ETFor more baseball news, rumors and analysis, follow @cbssportsmlb on Twitter or subscribe to the RSS feed.
