Rangers and Tigers get weekend sets going with a four-gamer beginning on Thursday

Mark Melancon (RHP, BOS) lived a nightmare against the Texas Rangers on Tuesday night, allowing a walk, a double, and three home runs without recording an out. For the season, Melancon has now allowed 11 ER in only two innings, for a 49.50 ERA. He has taken two losses and was removed from the set-up role in the season's first week. Melancon has options remaining, and on Wednesday he was sent to AAA-Pawtucket in an effort to let him straighten out his mechanics and clear his head. How does his demotion affect the Red Sox pen?

After spending Opening Day on the bench, Juan Pierre (OF, PHI) has since started five of the six games in which the Phillies have faced a right-handed starting pitcher. Just two years ago, Pierre swiped 68 bases and had an SBO of 43%, though those numbers dipped dramatically last year. He was successful on just 27 of his 44 stolen base attempts (61%), and had a 27% SBO. It's unrealistic to expect a full rebound for Pierre, now 34 years old, but he could still be a strong speed source, and has already stolen two bases this year.

Under-the-radar Andy Dirks (DH, DET) has taken advantage of his early opportunities in Motown. Can he continue to make an impact? We also take a look at some ailing pitchers in LAA and MIN, some scuffling OF in CIN, and a few significant injury updates.

There is never a good time to suffer an injury to a starting pitcher because of the lack of replacement options, but early in the season you do have a few more choices. Thus getting the jump on the potential injury situation is important. Here is a look at a handful of starters and their early season struggles. Are they struggling early on due to some sort of hidden injury or just early season rust?
