His elbow might be 'good to go', but having a ligament is not the same as a successful return from Tommy John! I am not very good with the advanced metrics, but the first thing I see is a very young lefthander who, in his only dominant season (2010), threw 40% sliders and (not surprisingly) blew out his elbow the following year. In addition, the slider accounted for the vast majority of his pitch value (slider 1.84, 2-seam 0.45, other fastball -0.5, change-up -1.5). Hey, this sounds familiar! I was becoming hopeful when I saw his 2012 stats, but became depressed when I saw that his 4 of his 6 end of the year starts were against the Twins, Indians, Red Sox and the Mariners. His final two starts, in a pennant race the A's did win, were against the Angels and Detroit and he got hammered (8 runs in 9 innings). Sounds really familiar! Finally, I see a pitcher whose BB/9 has gone from 1.76 in 2010 to 4.23 last year (OBTW, he walked 4 in those last 9 innings in 2012). That just seems like someone who either doesn't HAVE the stuff anymore, or doesn't TRUST it. It took Francisco Liriano 4 years, ~600 innings, and perhaps some bizarre "Rookie of the Year" mojo to bring his walk rate down to 3.5 (from >5 in 2011 and 2012). Is Anderson there yet? Will he be there in 2014 or 2015? If so, will he walk in 2016 just as we are ready to be competitive? I hate this... I started out not wanting to trade for another slider specialist, but now I have talked myself into it. Maybe Terry Ryan has talked himself into it as well, since in the news conference introducing Phil Hughes, he said something like "this situation is a lot like the Liriano situation last year, and maybe we can be on the other side of it this time"! Could it be a Freudian slip?
