Injury News: Fernando Martinez to DL, J.D. Martinez recalled from Oklahoma City

Injuries are changing Houston's Opening Day roster, as Fernando Martinez was placed on the 15-day disabled list thanks to a strained back. To take his place on the 25-man roster, the Astros recalled J.D. Martinez from Triple-A, giving them five outfielders on the roster again.

In other injury news, pitcher Alex White underwent an MRI on his shoulder after a troubling velocity drop recently. Here's the quote from Brian T. Smith's story:

White said Saturday he’s "always" dealt with minor triceps tendinitis. The issue stayed with him during Grapefruit League action this spring and "progressively got worse." His 6.86 ERA and 33 allowed hits in 16 2/3 innings may be partly attributed to triceps pain. He’s dealing with a velocity drop and was recently informed his four-seam fastball was only hitting 86 mph.

"There’s something wrong," White said. "That’s not normal."

White got roughed up in Friday's game, but if it was due to an injury, that's more understandable. If White joins F-Mart on the DL, there's a good chance that Edgar Gonzalez will be recalled from Triple-A to fill the role of the long relief man.

UPDATE: According to Smith, Alex White has been placed on the 60-day disabled list thanks to elbow soreness. Edgar Gonzalez has indeed been recalled from Triple-A to take his place
