The Phillies are having trouble scoring runs so the biggest burden has fallen on the pitchers, especially the starters. One of the keys is the starting depth Vance Worley provides the Phillies. He is projected to be a key cog in the Phillies plans as they wait for Utley and Howard to return. Is his elbow soreness something his owners should be worried about? Also, a look at Scott Rolen and David Robertson of the Yankees.

Alex Presley (OF, PIT) entered the season as a popular sleeper in many fantasy leagues after a mini-breakout campaign in 2011, but he hit only .220 in his first 118 AB. He has especially struggled over the past three weeks, going only three for 44 since April 29. His problems have been largely of his own making, as he's given back all of the skills growth that fueled last season's breakout.

Rafael Soriano (RHP, NYY) successfully converted a save opportunity May 10, when David Robertson (RHP, NYY) was unavailable after pitching the previous two days. Robertson was still expected to get the next opportunity, but Soriano got the call in the ninth on May 14, and again got the job done. As it turns out, Robertson was unavailable then as well, due to a strained oblique that is expected to sideline him for about three weeks. Those who have stashed Soriano away could be rewarded, as he is in line for saves now, and there's no guarantee Robertson reclaims the job when healthy.
