Jurrjens was charged with 11 runs, 10 of them earned, in 4 2/3 innings in the G-Braves' 14-7 loss to the Buffalo Bisons at Coca-Cola Field. In his first three Minor League appearances, he had allowed five earned runs in 22 innings of work (a 2.04 ERA).
"I saw box score and I said, 'Oh [wow]!," Gonzalez said prior to Thursday night's series finale with the Marlins. "But then you get the summary update from the manager and the pitching coach. That's the internal report that we get on everybody. He was better than [it looked]."
Gwinnett pitching coach Marty Reed believes that while Jurrjens may have had something of an off night, he wasn't as bad as the Bisons' official score book indicated.
"Last night might have been the worst scoring job I've seen in the history of baseball," said Reed, who has been around baseball for 30 years and whose past pupils include 2011 National League Cy Young Award winner Clayton Kershaw, '11 NL Rookie of the Year Craig Kimbrel, Jonny Venters, Brandon Beachy and Mike Minor. "He gave up four earned runs in the first inning. The guy basically dropped a fly ball in right field, and they scored it an inside-the-park home run, which cost him four earned runs. To be honest, it was atrocious.
"He gave up some runs, don't get me wrong. But the line score -- 11 runs, 10 earned -- that wasn't even close to the way he pitched."
There also was a double-play grounder that was mishandled that would have ended an inning.
Gonzalez admitted that he was relieved after reading the summary report from G-Braves manager Dave Brundage and Reed. He said he learned long ago not to trust box scores.
"Sometimes you see 4-for-4 and then you see the game report, and it's three broken-bat singles and an infield single," Gonzalez said with a laugh.
While Jurrjens' ERA took a hit -- it's up to 5.06 -- his health is fine.
Reed doesn't believe in putting too much stock in numbers, regardless, pointing out that they sometimes can play tricks.
"There are times when the numbers look good and the stuff isn't as good as you think it should be," he said. "[Jurrjens'] first game out, I think he went seven innings and gave up one run. When you just watch the stuff, it wasn't seven innings worth of stuff to give up one run. Sometimes you make good plays behind him, too. But I think he's progressing. He's making strides. He's able to work on some of the things that he probably needed to work on while he was up there.
"He's working on his physical strength. He's getting himself in really great condition. Our strength and conditioning coach Matt Parvis is spending a lot of time with him, and he's putting in the work. He's able to work on his changeup and try to get a little bit more on his fastball. You can't work on some of those things in the big leagues."
One thing Jurrjens hasn't had to work on is his attitude. That has remained professional on the field, and happy-go-lucky off it.
"As I told [general manager] Frank Wren and [pitching coach] Roger McDowell, this guy could not be any better than what he has been," Reed said. "[He's been] nothing but exemplary. His work ethic's been great, he's done a lot of the things that he's not used to doing, all the different little things you do in the Minor Leagues that you don't do in the big leagues. Tedious jobs and things like that, with no problems what so ever.
"Anything I've asked him to do, he's done it and he's done it with a smile on his face. I've got nothing but great things to say about how he's handled it."
