The righthander will officially be added to the Travelers' roster on Sunday, one year to the day after he made his first professional start for the Ogden Owlz. He will arrive having amassed 164 strikeouts in 145 innings as a starter.
Arredondo, who works with a fastball in the mid-90s, a slider and a split-finger which he uses for his out pitch, has a 2.20 ERA, the best for a pitcher still in the Cal League and second overall. He will follow Greg Smith, who left Lancaster with a 1.63, to Double-A.
The 22-year-old Dominican had five relief appearances in a fill-in role for the Travelers last May. He allowed two earned runs in five innings, walking and striking out four batters each.
It is believed that Christopher Hunter will move to the bullpen to make room for Arredondo in the Travs' rotation. The club had an extra spot on their roster already, so no corresponding roster move is expected.
