Matt Cain played all 13 of his seasons and 342 Games with the San Francisco Giants, a rarity in this day and age.  Cain made the starting rotation immediately and while he lost a lot of games early in his career, he hardly had a lot of run support and actually led the NL in Games Started in a season where he went 8 and 14 (2008).  He had an inverse record of 14 and 8 in 2009 and went to what would be his first of three All Star Games.  In those three seasons he had an ERA under 3.00 and he would assist the Giants win the World Series in 2010 and 2012 (he also threw a perfect game that year) and also won a third in 2014 though he was not a factor on the post season.  Cain retired with a losing record (104-118) but again that was not a reflection of his ability but lack of support early in his career.  Cain will always be known for the leadership he brought to San Francisco, which is why the team always held on to him.
