MESA, Ariz. -- Andrew Cashner threw three scoreless innings against the Cubs on Monday at Sloan Park, and then walked to the visiting clubhouse with manager Bud Black and a trainer, which certainly raised some alarms among fans.
"He's fine, baseball-wise. He threw the ball well," Black said. "There's a personal matter back in Texas I had to inform him of. So that's why I went in with Cash."
Cashner was gone by the time the Padres defeated the Cubs, 6-3.
Black said he wasn't sure if Cashner would be at the team's Spring Training facility for workouts on Tuesday morning.
Cashner needed 33 pitches to get through three hitless innings of work.
"He felt great, you saw the [good] velocity," Black said. "A couple good changeups, threw the slider a few times, but overall, I thought he kept the ball down with movement, [had a] good delivery, repeated his delivery.
"Very efficient innings, coming back on three days' rest. He's felt good all spring."
Cashner (1-0) struck out the first two batters he faced, then got Anthony Rizzo -- the player for whom he was traded in January 2012 -- to fly out to left field to end the first inning.
He issued a two-out walk to Mike Olt in the second inning but struck out David Ross for the final out of the frame. The third inning was a relative breeze as well, two groundouts and a flyout.
The outing was Cashner's longest of the spring, following the one inning he tossed on Thursday against the Mariners in Peoria.
