Martin was unavailable for the first two games of the series against the Padres due to an upper respiratory infection, Evan Grant of the Dallas Morning News reports. Martin was not at the park Saturday and may be held out for Sunday's series finale.
Martin is one of three pitchers that manager Jeff Banister indicated could get save opportunities, Dic Humphrey of MLB.com reports. The working assumption after closer Keone Kela was traded was that Jose Leclerc would be the primary closer, but the manager sent a different message Thursday. Banister said he feels he has three one-inning pitchers -- Martin, Leclerc and Cory Gearrin -- and refused to name a specific closer. He wants to retain the flexibility to utilize any of the trio when save opportunities are presented. The Rangers have not had a save situation since trading away Kela.
Martin (groin) will start a rehab assignment with Triple-A Round Rock on Sunday, TR Sullivan of MLB.com reports. Martin was able to throw a 20-pitch batting practice session Thursday, which was the final obstacle before heading out on a short rehab stint. The Rangers haven't formally announced how many appearances Martin will require in the minors, but it's expected that he will need multiple outings since he's been on the shelf for three weeks.
Martin was put on the 10-day disabled list due a left groin strain prior to Thursday's game. Martin was recalled from the minors before tossing an inning against the Astros on Wednesday. It appears as though he suffered this injury during that one-inning outing, which marks the second time he's landed on the DL in as many months. He previously spent 10 days on the shelf with a hamstring injury. He will be eligible to return July 15. In a corresponding move, Ricardo Rodriguez was called up from Triple-A Round Rock.
Martin was recalled from Triple-A Round Rock on Wednesday. The Rangers sent Martin packing just Tuesday, but he will return right away as an injury replacement for Tony Barnette (shoulder). Martin has posted a respectable 4.13 ERA in 24 innings with Texas this season, and his FIP is more than a run lower at 3.07. He currently leads the team with 10 holds -- Alex Claudio, Jose Leclerc and Jake Diekman all have nine.
