Wood to be clean shaven for first MLB start

ATLANTA -- Alex Wood appeared calm on the eve of his first Major League start, which will be in the first game of Tuesday's doubleheader against the Mets. With the benefit of six relief appearances in the Majors already under his belt, Wood has been able to adjust to the bright lights at a comfortable pace.

"That's the biggest thing is getting your feet wet a little bit," Wood said. "It takes all the weight off your shoulders, and once you're there and you know you can do it, it's exciting because it'll be my first start, but at the same time, it's nothing compared to how it was when I made my debut."

But before the left-hander makes his first start in over three weeks, he will have to shave for the first time in roughly two weeks.

Under the supervision of the more veteran members of the Braves' bullpen, Wood started working on a beard a few days after he was called up on May 30. With his return to the starting role he served in throughout college and the Minors comes a return to his typical clean-shaven look.

"That's definitely coming off," reliever David Carpenter said on Monday with a motion toward Wood's beard. "If you're going to have that GS [games started] column with a '1' in it, at least shave for the day, and then it can start over again."

Wood's movement from a starting role to the bullpen has provided a few more significant adjustments than how he manages his facial hair. His last start for Double-A Mississippi came on May 25, so he's not too far removed from his pre-start routine -- from standardizing his pregame meals to getting his arm loose at his own pace.

The Braves will call up reliever Cory Rasmus from Triple-A Gwinnett to fill the 26th spot on their roster for Tuesday's doubleheader. The presence of Rasmus, who appeared in two games in late May, will help take the pressure off a Braves bullpen that could be in for a busy week with five games in four days and rain in the forecast. On Sunday night, manager Fredi Gonzalez said that the Braves would take an inning-by-inning approach with Wood and his pitch count in his first start.

"I think it's just going to be -- see how I feel as it goes along," Wood said. "As long as I'm throwing well, I think I can get back up there close to 100 [pitches] if I have to. It's been three weeks, but I've been throwing. Obviously, I'll probably get fatigued a little faster than normal, but it's one of those things where my body knows when I'm going out there starting, so I'll adapt as the game goes on, and hopefully, I can get some good innings tomorrow."

As for the beard, Carpenter let on that Wood may be subject to a little more rookie hazing at the hands of his fellow relievers when he returns to the bullpen after this week's series.

"We had to come up with one real quick, and that's just kind of what we went with," Carpenter said of the beard. "His day is coming. You guys will write about what's coming. It will be well-documented."

Minor setback has Beachy frustrated, but focused

ATLANTA -- Members of the Braves' medical staff praised Brandon Beachy for the discipline and dedication he showed after undergoing Tommy John surgery on his right elbow. His hard work was credited to the fact that he went nearly a full year without experiencing any of the expected setbacks.

But in a cruel twist of fate, the minor setback came eight days before the one-year anniversary of this surgical procedure. An MRI performed on Friday showed inflammation around Beachy's elbow.

So instead of making his return by starting a game during Tuesday's doubleheader against the Mets, Beachy will now have to wait a little longer. It is too early to set a potential timetable for his return. But the team and pitcher continue to view this as just a minor setback that happened to occur a little later than normal following Tommy John surgery.

"That's what makes it even more frustrating," Beachy said. "But I've just got to keep working and remain focused on getting back out there."

Beachy said he has experienced some improvement in his right elbow over the past few days. The Braves had the 26-year-old pitcher undergo the MRI after he walked three and needed 69 pitches to complete three innings in what was supposed to be his final Minor League rehab start for Triple-A Gwinnett on Thursday.

Beachy now admits he experienced some stiffness around his right elbow during each of his final three rehab starts. This did not cause any pain and he was hoping he could continue pitching through this minor ailment that most pitchers experience at some point after undergoing Tommy John surgery.

Worth noting

• Gonzalez claimed his 500th career managerial victory with Sunday night's win over the Giants. Gonzalez entered Tuesday with a .570 (224-169) winning percentage since becoming the Braves' manager before the start of the 2011 season. The Yankees (.585) and Rangers (.578) are the only Major League clubs with better winning percentages during this stretch.

• B.J. Upton entered Tuesday having hit .250 with four home runs and a .946 OPS in June. His six extra-base hits this month are two fewer than his combined total from April and May.
