PITTSBURGH _ After feeling no discomfort for the first time in two months after his latest throwing session, Yu Darvish admitted to some of frustration over the uncertainty surrounding when he can rejoin the Cubs.
"As much as it's a mystery to you guys, it's more of a mystery to myself because I'm the one trying to process and grind through," Darvish said.
Darvish did lend some insight into his rehabilitation from the right triceps tendinitis that has prevented him from pitching for the Cubs since May 20.
Darvish believes he will throw a two-inning, 40-pitch bullpen session sometime this weekend if his body responds well to Tuesday's bullpen session, in which he threw his full array of pitches during a 35-pitch outing without any discomfort.
"It's hard to compare, but I'm certain it won't take as long as it took in spring training to build up (strength)," Darvish said. "It's a starting point. Everything from this point on will go positively."
Darvish admitted he still needed to work on command of all his pitches, including his fastball.
"But it's a starting point," Darvish said. "I'm really excited. There was no pain."
The prognosis for third baseman Kris Bryant (left shoulder) and closer Brandon Morrow (right biceps), however, remains cloudy. Bryant has yet to swing a bat, and Morrow hasn't resumed playing catch.
Reliever Anthony Bass (right back shoulder) threw a bullpen session Tuesday. He is scheduled to throw another bullpen session this weekend with the hope he will start a minor-league rehab assignment shortly after.
