SAN FRANCISCO -- Nationals left-hander Gio Gonzalez, on the disabled list with left shoulder inflammation, will pitch in his second rehab game for Class A Advanced Potomac on Thursday. Manager Matt Williams said that if things go well, Gonzalez will be back with the Major League team next week.
In his last start for Potomac, Gonzalez was hit hard, allowing eight runs in 3 2/3 innings, and the Nationals declined to bring him back to the big leagues.
With Gonzalez expected to come back, the Nationals most likely will send Blake Treinen back to Triple-A Syracuse. Treinen has been outstanding during his brief time with the Nationals, allowing five earned runs in 25 1/3 innings. He is scheduled to start against the Giants on Thursday afternoon.
Williams admitted it would tough to send Treinen down.
"It's never easy, but he is still in the learning process as far as starting pitching goes," Williams said. "... But it's never easy to send somebody out, especially when [he has] contributed to your team's winning and has done the job that he has done for us."
