Eaton was recently pulled off his minor league rehab assignment due to renewed discomfort in his elbow. Towers said an MRI showed fluid around his ulnar collateral ligament, but no new damage was found. As of now, he's expected to rest for 2-3 weeks before restarting his rehab program, but he'll get Andrews' opinion just to be on the safe side.

Eaton suffered a sprained UCL in March and has been dealing with renewed discomfort. The outfielder will spend the next 2-3 weeks doing strength and conditioning work before attempting to resume a throwing program. He can be ruled out until at least late June. It's a disappointing setback for one of 2013's biggest fantasy darlings.

Prado is still hitting for a better average this month and he did in April, but that's not saying much. He's gone 12 straight games without scoring a run. He has two runs scored and four RBI in 20 games overall for the month. And not only is his season OBP a lousy .283, but he's been caught on three of his four steal attempts. Good thing the Diamondbacks gave him that four-year, $40 million deal before some team could blow them out of the water this winter.

Bad news. Eaton, who was diagnosed with a sprained ulnar collateral ligament in March, began playing in rehab games earlier this month and felt well enough to return to center field last week. However, the pain has returned. The worst-case scenario would be season-ending Tommy John surgery, but it's not clear if that's a consideration yet. But it's obviously a concern.

The struggling backstop is getting a rest with the early start time. Wil Nieves will make the start behind the plate.

The seldom-used 35-year-old has slashed .280/.321/.280 through 28 plate appearances. Nieves, who entered 2013 a .229/.274/.301 career hitter over nine major league seasons, will continue to play sparingly behind starter Miguel Montero.

That will be two weeks after Hill was hoping to get the go-ahead to resume baseball activities, as his fractured hand is healing much slower than expected. The original timetable had him possibly returning by late May, but he probably won't be activated until well into June now.
