Winning streak: Roy Oswalt returns from the disabled list and looks to extend the Phillies' winning streak to 10. To reach double digits, Philadelphia will have to top Tim Lincecum. Lincecum set the tone last postseason against the Phillies, topping Roy Halladay in Game 1 of the NLCS, before losing Game 5 in a rematch against Halladay. A little more than a week ago, Lincecum threw six shutout innings in a victory in Philadelphia in a 4-1 Giants victory over Kyle Kendrick. Philadelphia's Roy Oswalt is making his first start since June 23, spending the last six weeks on the disabled list with lower back inflammation and two bulging disks. Phillies at Giants, 4:05 p.m. ET
Losing streak: On the other side of Pennsylvania, the state's other team is looking to avoid a 10-game streak of its own. Pittsburgh has lost its last nine and 11 of its last 12. The Pirates now trail the Brewers by nine games and any shot at making the playoffs seems remote at best. The team may now have to change its focus from the postseason to ending the streak of 18 consecutive losing seasons. The Pirates stand at 54-58, so that's a more realistic goal than the playoffs at this point. All-Star Kevin Correia (12-9, 4.71 ERA) starts for the Pirates opposite San Diego's Mat Latos (5-11, 3.94). Padres at Pirates, 1:35 p.m. ET
Hitting streaks: Braves second baseman Dan Uggla extended his hitting streak to 27 games on Saturday, going 3 for 5 with his 24th homer of the season on Saturday in a loss to the Mets, but he's not alone on the Braves' streaking list -- rookie first baseman Freddie Freeman singled in the third inning to extend his hitting streak to 20 games. Uggla's homer was his 12th during the streak and has seen his average rise from .173 to .220 during the streak. He's 2 for 8 against Sunday's Mets starter Dillon Gee. Freeman is 1 for 5 against Gee. Braves at Mets, 1:10 p.m. ETFor more baseball news, rumors and analysis, follow @cbssportsmlb on Twitter or subscribe to the RSS feed.
