PHILADELPHIA -- Thursday afternoon will be the home debut of Phillies left-hander Cliff Lee, the Trade Deadline acquisition the team hopes will make them back-to-back World Series champions.

As far as the proceedings at Citizens Bank Park are concerned, Rockies right-hander Aaron Cook is just the other guy.

Actually, Cook deserves some billing, based on his recent accomplishments. Cook has earned seven straight wins. Before Jorge De La Rosa gave up seven runs and 10 hits in five innings in a loss to the Phillies on Tuesday night, Cook and he were tied for the longest active winning streak among Major League starters.

But the Rockies didn't make the headlines that come with acquiring a starter at the Deadline, so Lee is the headliner. That's fine with Cook, who is part of a rotation that the Rockies feel is good enough to press for a playoff spot.

"We've got five guys in our starting rotation right now that we can throw out there against anybody," Cook said. "We feel comfortable that we can win the game. That's nice to have. We don't care about the notoriety. We don't care about the national attention. We just want to go out there and win games."

Cook has been a major part of that. Cook's streak has been over 11 starts, during which he has posted a 2.97 ERA over 72 2/3 innings. Cook has stayed in the strike zone throughout his run, with 45 strikeouts against 16 walks.

Rockies manager Jim Tracy is confidently sending Cook to the mound. Tracy said he respects Lee, and the Rockies have some familiarity after having faced him in Spring Training.

"You don't win Cy Young Awards by mistake," Tracy said. "He's a very competitive opponent. We must be mindful of that.

"Your starter has to be equal to the task."

Pitching matchup
COL: RHP Aaron Cook (10-3, 3.88 ERA)
Cook was solid for most of his 6 2/3 innings in Friday night's Rockies victory over the Reds, but he didn't figure in the decision. His biggest problem, besides the consecutive home runs by Joey Votto and Brandon Phillips in the sixth, was the Rockies didn't find their offensive stride until late in the game. Cook gave up seven hits, but forced 10 ground-ball outs. He'll need to keep the ball low against the dangerous Phillies at Citizens Bank Park, a similar bandbox to Cincinnati's Great American Ball Park.

PHI: LHP Cliff Lee (8-9, 3.02 ERA)
Lee couldn't have had a much better debut for the Phillies on Friday against the Giants at AT&T Park. He threw a complete game. He allowed one run, four hits and two walks in a 5-1 victory. He struck out six. Oh, he also went 2-for-4 with a double -- the first extra-base hit of his career. He worked efficiently and effectively, and made the Phillies feel pretty good about acquiring him July 29 from the Indians for prospects Carlos Carrasco, Lou Marson, Jason Donald and Jason Knapp.
