• Jeff Niemann (fractured right fibula) will continue his rehab assignment by reporting to Triple-A Durham to make two starts. If all goes well, the Rays could have an interesting problem in trying to figure out how to handle a full starting rotation. Niemann made his second rehab start for Class A Charlotte on Tuesday night and allowed four runs on six hits in 3 1/3 innings.

• Desmond Jennings entered Wednesday's contest against the Mariners with a seven-game hitting streak. During that span he has hit .519, scoring 11 runs while collecting four doubles, a home run and three RBIs.

• The Rays lead the American League in ERA, strikeouts and opponent's batting average. They are 12-4 with a 1.58 ERA in their last 16 games, and 16-8 with a 1.58 ERA in their last 24.
