BOSTON -- As much as almost any hitter in baseball, San Francisco Giants outfielder Angel Pagan has faced Drew Pomeranz at every stage of the lefty's winding career -- in 2012, when he was a fledgling starter for the Colorado Rockies; in 2015, when he was sent to the bullpen by the Oakland Athletics; this season, when he emerged as an All-Star with the San Diego Padres.
But as Pomeranz makes his Boston Red Sox debut Wednesday night at Fenway Park, not even Pagan knows what to expect.
