A Poem for Mark Prior

Mark Prior is making a comeback. Here is a poem in commemoration.

Mark again,
  a rising and daring,
  a burning without exhaustion,
  a heat with dangerous form,
  not like the fire without an end,
    but the coals, under the ashes and warm.

A mark from before,
  a promise unkept,
  a hero unkempt.
  A man seen only in white and red and blue —
  the same still, but now in red and blue and white,
    all shades different, but not askew.

Our prior notation,
  a classic tale,
  a useful trope.
  Kerry Wood ended with a K.
  Bartolo Colon just kept going.
    And now what will remain?
