Brian's been pretty good out of the rotation, much like last year. He bounced back to gut through seven and a third following a rough start his last time out, and in total has amassed 24.1 innings in four starts. In that stretch, opponents are hitting just .269/.306/.376. That's not bad.
He likes to work away, and tends to try and get right-handed hitters to chase outside a bit more. Against lefties Duensing loves his slider and, just like Liriano, only throws the changeup about 1% of the time. With his curve almost more of a "show me" pitch, against lefties he's almost exclusively fastball-slider.
Cahill is having an absolutely brilliant season. Largely because it's friggin' impossible to pick up a hit against the 22-year old right hander. All four of his pitches have been a plus this year, especially his fastball. It's been an absolutely sick pitch, which isn't bad for a guy who will average about 90 mph.
He induces a lot of ground balls, which help him limit extra base hits for the lucky souls who do get one to find grass. Looking at his results, he's great at finishing off hitters, he's great at retiring the first batter of the inning, 40% of his innings are 1-2-3, more two-strike at-bats turn into outs than most, and he's very good at turning hitter's counts into outs.
