The latest of these is the Nationals' Tanner Roark, the right-hander who made a splash late last season (7-1, 1.51 ERA) while showing comparable effectiveness both as a starter and in the bullpen.
Lefty hitters had been much more successful against Roark in his first five starts thus far in '14 (1.011 OPS going into today's game against the Padres), but he had an ace up his sleeve: he's been almost preternaturally effective at home in Nationals Park.
That continued today, when Roark retired the first 16 San Diego batters he faced en route to a three-hit complete game shutout--a first for him in each category.
