Joe Ortiz made the Rangers' club out of Spring Training and pitched reasonably well in a couple of stints with the team by not walking anyone, but failing to miss any bats as well. He should be back with the big league team once the AAA season ends and MLB rosters expand to 40. When looking at a GIF of his delivery, the first thing you notice is his odd size:
Cory Burns was traded to the Rangers in the off-season by the Padres for Wilfredo Boscan. Burns has very limited time in the big leagues with both clubs, but has been downright dominant in the PCL the last two years (FIPs under 2.00 both times). Burns has a weird turn in his delivery that he has to get rid of with runners on base. He still didn't hold runners on at all:
Ben Rowen makes the uniqueness of Burns seem trivial with his submarine delivery. Rowen has not pitched in the Majors, unlike the two above, but he has been dominant in AA and AAA:
Especially considering it was Spring Training and a small sample size, we should be cautious paying attention to pitch locations for Rowen. MLBAM thought Rowen's fastball was a changeup, so I changed it to a fastball. It was the only pitch he could get down in his Spring Training outings.
