The Philadelphia Phillies and pitcher Cole Hamels' representatives expect to ramp up the pace of contract talks this week as they approach what a source said is a "sensitive" stage of negotiations.

The two sides took a brief hiatus over the weekend, as Hamels pitched against San Francisco on Saturday in Philadelphia and agent John Boggs was traveling. But people familiar with the situation said time is of the essence as the Phillies try to reach an agreement with the three-time All-Star. With only eight days left until the July 31 non-waiver trade deadline, the Phillies need to save themselves a window to re-engage with potential trade partners if they can't reach a deal with Hamels.

The Phillies have offered Hamels a six-year contract in the neighborhood of the $127.5 million extension that Matt Cain received from San Francisco in early April, according to sources, but Hamels has several items to consider as he contemplates whether to sign with the club.
