Happ to start series opener vs. Cubs

Philadelphia (61-48) at Chicago (58-51), 8:05 p.m. ET

PHILADELPHIA -- After tossing a four-hit shutout in his previous start, Phillies rookie lefty J.A. Happ will take the ball in Tuesday night's series opener against the Cubs at Wrigley Field.

Pedro Martinez, who was also a candidate to start Tuesday, will make his Phillies debut Wednesday. The 37-year-old right-hander struck out 11 in a six-inning rehab start for Double-A Reading last Wednesday.

For the past week, Philadelphia has avoided making -- or at least announcing -- tough choices regarding its starting staff. The club has six quality starting pitchers. Cole Hamels, Cliff Lee, Joe Blanton and Happ have four spots locked up. Manuel had said that Martinez will get multiple chances to showcase his starting abilities, with the first one coming Wednesday. But Manuel also has conveyed tremendous respect for Jamie Moyer, who has a team-high 10 wins this season, and 256 for his career.

Philadelphia could go with a six-man rotation or some other unconventional setup. General manager Ruben Amaro Jr. said that is possible. But that could mean fewer innings for the team's top arms, and pitching coach Rich Dubee said he does not like the idea.

Pitching matchup
PHI: LHP J.A. Happ (8-2, 2.74 ERA)
Happ has been contributing all season. His last outing was his best as he struck out a career-high 10 while shutting out the Rockies on four hits in a 7-0 Phillies victory.

CHC: RHP Rich Harden (7-7, 4.41 ERA)
Harden is healthy and has found a groove lately. Over his past five starts, the flamethrower is 2-1 with a 1.80 ERA. More impressively, over that span he has 41 strikeouts and nine walks in 30 innings. He fanned 20 over his past two outings, even though he won neither. Harden has dominated the Phillies over his career, striking out 22 and allowing just two earned runs over 20 innings (0.90 ERA).

The Phillies were last swept by the Marlins from July 26-29, 2004. ... Sunday's game was the 50th sellout of the season for Philadelphia, tying last year's club record. ... The 19 hits the Phils allowed Sunday were a season high.
