Comments on: Bonser Looks to Go Under the Knife http://www.fangraphs.com/blogs/index.php/bonser-looks-to-go-under-the-knife/ Daily baseball statistical analysis and commentary Mon, 13 Feb 2012 01:07:28 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: thrylos98 http://www.fangraphs.com/blogs/index.php/bonser-looks-to-go-under-the-knife/#comment-63847 thrylos98 Wed, 25 Feb 2009 03:10:13 +0000 http://www.fangraphs.com/blogs/?p=3224#comment-63847 I would not think that the situation is quite as dire as projected :) first of all, Bonser is getting an exploratory arthroscopic procedure done on his shoulder to figure out where the pain comes from because MRIs and X-rays cannot find anything. The good news with this is that there is probably no ligament or muscle damage (or even inflammation because a cortisone shot was ineffective) or bone spurs (those would have popped out in those exams). In decreasing severity, it could be scar tissue (that can be scraped by the scope), fluid build up, something funky, or good old arthritis (that's a bad thing; career ending.) That said, scopes are practically a weekly occurrence in football locker rooms and players who undergo such a procedure usually are back on the field within a week or two. Regarding how bad a blow this could be for the Twins. Perkins with all his inadequacies is ok for a 5th starter and projects to something like 1.9 wins above replacement. Bonser has great stuff and this would be the season that he would officially make an 100% transition to the pen and fight fot the set up job. In the organization's mind he is not a starter any more. Even in the worse case scenario that Bonser would be unavailable for this season, his 0.6-0.7 WAR in the pen would be easily replaced by Ayala, esp. if he rebounds. Duensing, Swarzak, Mulvey (even Humber) are waiting in the wings if Perkins falters. In the big schema of things this is not a big deal for this season.
