Nathan was unavailable the past few days due to elbow soreness, but is available Monday, Matthew B. Mowery of the Oakland Press reports. Nathan may have been unavailable the past few days, but the team was never in a situation where they needed him. The 39-year-old has struggled in the closer role for the Tigers this season, posting a 5.04 ERA and 1.54 WHIP while blowing six saves. His K/IP ratio has also dipped below one for the first time in three seasons (0.98). At any rate, he will likely continue as the Tigers' closer for the remainder of this season, and is under contract for another, so it will be interesting to see what the team decides to do with him in the offseason.
