He may be more likely to stick around if the Phillies can get on a roll.Visiting Philadelphia tries to win back-to-back games for the first time in nearly three weeks Sunday afternoon in the series finale with the Colorado Rockies.The Phillies (38-51), who had been outscored 70-40 in dropping 11 of 12 since posting consecutive wins June 25 and 26, broke out in a big way during Saturday's 8-5 victory at Coors Field. Carlos Ruiz hit a three-run homer and Chase Utley had three hits and two RBIs for Philadelphia, which went 5 for 7 with runners in scoring position."We were talking at the All-Star game and saying that we have to pick it up in the second half," said Ruiz, who joined closer Jonathan Papelbon at Tuesday's All-Star game. "We know we've been struggling and this was a big moment for us, a big win for us."Sitting 14 games behind NL East-leading Washington, Philadelphia will soon need to decide what to do with Hamels (10-4, 3.20 ERA). The left-hander, who's been in talks with the Phillies about signing an extension, also remains a candidate to be traded."I'm not the one up in the front office. That's not what I signed up for. So I don't stress over that," he told MLB's official website."What I've been trying to do, day in and day out, is just play baseball. I understand the nature of the business. I really do. It's only going to be speculated because of the situation that we're in. In this day and age, with guys getting traded a lot more, and free agency obviously coming up, I think it's just the business side."Hamels hasn't been very sharp on the road, compiling a 5.46 ERA over his last four outings. In his final start before the break, Hamels gave up four runs in seven innings of a 6-5 loss to the New York Mets at Citi Field on July 5.Hamels, who matched career worsts with seven earned runs and 11 hits allowed over 3 2/3 innings of a 10-3 loss at Colorado on April 10, 2009, has since gone 2-0 with a 2.05 ERA over three starts in this series. He limited the Rockies to two runs and six hits in eight innings of a 7-2 victory June 19.Marco Scutaro is 3 for 18 lifetime against Hamels while Dexter Fowler is 1 for 10. Michael Cuddyer is 0 for 7.Losers of 11 of 15 at home, the Rockies (34-53) try to get back on track behind Drew Pomeranz (1-3, 3.06). Sent down to Triple-A Colorado Springs after going 0-2 with a 4.70 ERA over his first five starts, Pomeranz hasn't allowed an earned run in two outings spanning 12 1/3 innings since getting recalled July 1.The highly-touted left-hander outdueled Stephen Strasburg during a 5-1 win at Washington on July 6, allowing one hit and striking out six over 6 1/3 scoreless innings."I see not only a different pitcher right now, but I also see a different person, and that's just as important as the physical aspects that we talk about at length," manager Jim Tracy said. "The person is completely different from the guy we were dealing with in spring training ... he has a different demeanor, his business-like approach has changed."Pomeranz has never faced the Phillies.
