Santana could make final Minors start this week

MILWAUKEE -- While Mike Minor and Gavin Floyd are still in the early stages of their rehab stints, Ervin Santana will make what could be his final Minor League start this week.

Braves pitching coach Roger McDowell said Santana is scheduled to complete up to six innings for Triple-A Gwinnett in Friday's game against Durham. If Santana gets his pitch count up around 100 and exits the outing feeling strong, there is a chance he could start Atlanta's April 9 game against the Mets.

Since signing Santana to a one-year, $14.1 million contract on March 12, the Braves have said they would not rush him through his preseason preparations. Thus, manager Fredi Gonzalez said there is still a chance Santana's debut might not come until the April 14 series opener in Philadelphia.

Minor, who was behind schedule during Spring Training because of a Dec. 31 urinary tract procedure, and Floyd, who is attempting to return from Tommy John surgery, are both in line to potentially join Atlanta's rotation at some point after April 21.

While Minor will attempt to complete three innings for Double-A Mississippi on Thursday, Floyd will be in Durham attempting to do the same for Gwinnett. The two pitchers are currently scheduled to complete four innings in piggyback fashion for Gwinnett on April 8.

Schlosser shows why he's an asset in Majors debut

MILWAUKEE -- As Spring Training neared its end and it became apparent he would begin the season at the Major League level, Gus Schlosser maintained his stoic, even-keeled approach. But Schlosser was reminded that he is human as he dealt with the nerves that he felt before making his Major League debut in Monday's 2-0 Opening Day loss to the Brewers.

Once Julio Teheran completed his six innings of work, the Braves assigned southpaw Ian Thomas to face the two left-handed hitters -- Lyle Overbay and Scooter Gennett -- the Brewers sent to the plate to begin the bottom of the seventh. As this transpired, Schlosser knew he would enter as soon as a right-handed hitter came to the plate.

"I was pretty [darn] nervous," Schlosser said. "I might have hid it well. You've got to expect it. The [veteran] guys in the bullpen told me to just keep breathing. It helped a lot."

After Gennett ended Thomas' debut with a single, Schlosser entered and promptly got Rickie Weeks to ground into an inning-ending double play.

Schlosser could be utilized as a long reliever or potentially return to Triple-A Gwinnett to fortify the organization's depth in the starting pitching department. But the Braves also recognize that his ability to sink the ball with his sidearm delivery could make him a valuable asset during the middle innings.

"It's all relative," Schlosser said of the different roles he could encounter. "You either make pitches for a hitter or you make pitches for seven innings. Whatever they need me to do, I think I'll be fine."

Fredi reflects on historic overturned call

MILWAUKEE -- Because it was something he had never experienced during any of his previous seven seasons as a Major League manager, Fredi Gonzalez said it felt like he was on the field for at least 10 minutes when he challenged first-base umpire Greg Gibson's call during the sixth inning of Monday's Opening Day loss to the Brewers.

But once he had time to review the sequence of events, Gonzalez learned that just one minute and 38 seconds elapsed from the end of the disputed play until the umpiring crew overturned the call after the play had been reviewed by an umpire in Major League Baseball's Replay Operations Center.

The decision to reverse Gibson's original ruling that Brewers outfielder Ryan Braun beat third baseman Chris Johnson's throw to first base proved to be historical. It will forever stand as the first call overturned through the use of MLB's expanded replay system, which was first utilized on Monday.

"It worked exactly the way they wanted it to work," Gonzalez said. "It just didn't feel like baseball. It felt weird. When you come out of the dugout, you're looking to protect your players, you're looking to yell at the umpire or get into a confrontation. But that never even occurred. [Gibson and I] were like two civil guys talking."

As he briefly conversed with Gibson in front of the first-base bag, Gonzalez stalled long enough for his replay coordinator Horacio Ramirez to review the play in the clubhouse and then quickly inform bench coach Carlos Tosca that the play should be challenged.

Gonzalez found it comical that some fans and at least one of his own players were confused when the challenge was issued after Tosca provided a thumb-down sign that was caught by television cameras. While a thumb-up sign might have seemed more appropriate, Gonzalez said all that mattered was that he and Tosca were on the same page.

"Does it matter what he does?" Gonzalez said. "It's something we came up with. It could have been take your hat off or whatever. That's something we came up with. It's nothing. It's just a sign."
