SAN DIEGO -- Nationals left-hander Gio Gonzalez will get another rehab start for Class A Advanced Potomac on Wednesday, according to manager Matt Williams.
The team was not happy with Gonzalez's outing against Wilmington on Friday. In that game, Gonzalez allowed eight runs in 3 2/3 innings in an 11-10 victory. In his next outing, which will be against Carolina, the Nationals would like to see Gonzalez have better command of his pitches.
But, first, Gonzalez will have a bullpen session at Nationals Park on Monday.
"Arm strength is one thing, but he was all over [the place]," Williams said about Gonzalez's outing. "He didn't walk a bunch of guys. His command wasn't what he wanted it to be. [In his next start], we'll take him to five-ish innings and 80 pitches and see where he is at. We'll see if there is any improvement from his last time outing."
The plan for Gonzalez means that right-hander Blake Treinen will get another against start against the Giants on Thursday.
Gonzalez has been on the disabled list since May 18 with shoulder inflammation
Rendon listed as day to day
SAN DIEGO -- Nationals third baseman Anthony Rendon was not in Saturday's starting lineup against the Padres because of a sore right thumb. Kevin Frandsen started in his place, hitting second.
Manager Matt Williams said Rendon's thumb is better than it was Friday, when he left the game in the top of the sixth inning. He hurt it while committing an error two innings earlier on a ball hit off the bat of Carlos Quentin. X-rays on Rendon's thumb were negative.
"He is doing contrast treatment -- ice and heat--flushing some blood out of there," manager Matt Williams said. "It a little swollen. Pretty sore. We have a quick turnaround tomorrow. We have to see how it is. The good news is, there was no fracture. It's better than last night, not as much swelling as there was yesterday, but it's still sore."
