While Rockies’ starter Chad Bettis is dealing with a blister on his finger that landed him on the disabled list at the major-league level, down at Triple-A Albuquerque, reliever Zac Rosscup is fully healed — and pitching with promise — coming off a left middle-finger wart that sidelined him for the first third of the season.
Since being reactivated June 13, the left-hander has posted a 1.23 ERA and 0.95 WHIP in nine appearances out of the Isotopes’ bullpen as he’s regained the feel for his slider that the wart took away.
“The slider has really come around and has the effect that it used to, in terms of being that wipe-out pitch that he has in his back pocket,” Rockies farm director Zach Wilson said.
