Just days following the Zack Greinke trade, the Brewers made yet another roster splash when it was announced they had recalled 22-year-old and newly acquired shortstop Jean Segura from double-A Huntsville to take over the starting job at shortstop on Monday night. Segura, the centerpiece to the aforementioned trade, held a stifling .433/.500/.533 line in his first eight games with the organization and apparently received a vote of confidence from management having been recalled to the big-league roster just days after being dealt.

The transaction may have seemed a bit abrupt to some, but it should come as no surprise to most that the Brewers are in somewhat of a rush to indoctrinate many of their top prospects to the big-leagues. General manager Doug Melvin and owner Mark Attanasio remain staunch in their believe that Milwaukee will have the pieces necessary to compete for a division title in 2013, and its tough to argue with that notion when you consider the fact that A.) The Brewers have witnessed significant improvements down on the farm this season, B.) They [should] be at full health by the start of next season and also that C.) Rickie Weeks’ god-awful offensive yield this season can’t possibly replicate itself over 162 or some odd games next season.

In all seriousness, though, there should be no reason to believe Milwaukee won’t have those essential pieces to make a run at the playoffs next season. However, as this season begins to wind down, there are a few things that have yet to be checked off the “to-do” list, and it all begins on September 1 when rosters expand from 25 to 40.

Which Brewers prospects have the best odds of being recalled to Ron Roenicke’s 40-man September roster? Let’s start our list by ranking the five most plausible:

1.) Tyler Thornburg, RHP (stats)

Making mince meat of double-A Southern League hitters in the first half of the season, Thornburg became the darling of Brewers fans everywhere when he made his first big-league start on June 19. Since then, he’s seen limited time, making just one other start to go with three separate relief appearances for Ron Roenicke. Consequently, management demoted back to triple-A Nashville on July 30 for him to regain his rhythm as a starter, and he’s performed well ever since.

In a system that’s been yearning for a young player to step up and fill at the very least a somewhat important role this season, Thornburg has made his name known. For that reason, you can wager your mortgage that he’ll be on the 40-man September roster.

2.) Wily Peralta, RHP (stats)

Command issues plagued the early stages of what looked to be his final season in the minors, but after making his big-league debut in late April, he’s come around quite nicely. This past month, Peralta, 23, posted a 2.78 ERA and 1.31 WHIP over six starts, held batters to a .275 batting average and struck out over a batter per inning. His first August start was one to forget (3.2 IP, 5 ER, 6 BB, 6 K), but his swing-and miss stuff that has made him Milwaukee’s top hurler on the farm still remains.

With such a blatant shortage of arms out of the bullpen, it’s tough to imagine a scenario where Peralta isn’t on the 40-man roster come September; the Brewers have questions to answer regarding their starting-five next season, and they’ll need to determine if he’s the mid-to-backline starter scouts project him becoming in the near future.

3.) Logan Schafer, OF (stats)

My top-rated Brewers position prospect when the season started, Schafer’s entire 2012 campaign has been spent in triple-A Nashville where he’s strove to return to the big-league roster as he did last September. But after a strong spring training, Schafer struggled to hit the  ball where defenders were not, resulting in an uncharacteristically low .266 average between April and May. Schafer regathered himself to hit a scintillating .354/.385/.521 in June but was equally as abhorrent in July where he posted an on-base percentage of .197 — yes, 1.97. To make matters worse, Schafer was placed on the 7-day disabled list on July 30 where he was reported to have a sore left knee and hasn’t suited up since.

Seen as a player with a chance to see legitimate playing time in 2013, things just haven’t gone Schafer’s way this season and his odds of making the 40-man roster next month have consequently taken a beating. I still think there’s a very good chance he’s recalled, as Roenicke could use his base-running prowess on a few occasions,  but not to the extent of which we all previously thought.

4.) Taylor Green, 2B/3B (stats)

Receiving a decent amount of playing time after his recall from triple-A in early May, Green’s offensive output just wasn’t up to snuff and he was demoted back to Nashville early on in July, where the Brewers hoped he’d return to his slugging ways just in case Aramis Ramirez was dealt (it didn’t happen) at the trade deadline.

Unfortunately, Green hasn’t been able to tap into his power stroke, garnering just a .372 slugging percentage between July and August. He’s still a serviceable defender at third but all signs point to Ramirez sticking there for the remainder of the season as his own statistics continue to climb. Expect Green on the 40-man roster but as a pinch-hitter/runner almost exclusively.

5.) Caleb Gindl, OF (stats)

Coming off one heck of a 2011 season in triple-A where he hit .307/.390/.472 with a .357 BABIP, Gindl too seemed on the cusp of getting some real playing time by the beginning of 2013. A disciplined hitter with a very good approach at the plate, the stocky outfielder impressed Ron Roenicke this past spring. Since then, he’s been anything but impressive (at least up to his standards). With a career-worst .246/.302/.392 line to go with a heightened amount of strikeouts and diminished walks, Gindl’s big-league future has been put in serious doubt and his odds at making the 40-man roster have also taken a blow.

The Brewers are and will be heavy in outfielders, so there’s a slim chance he gets any substantial playing time should he make the September roster. Right now I’d say he has a 50/50 shot at making it.

Others (in no particular order)

Johnny Hellweg, RHP — A bit of a stretch considering he’s still in double-A ball, but its tough to ignore a guy who throws upwards of 100 MPH and has future strikeout machine written all over him. Will need to work on control issues but some big-league experience next month would do him wonders.

Jeff Bianchi, SS — Despite Segura and Cody Ransom already on the roster, the Brewers simply cannot get enough infield help so they might as well consider promoting him next month.

Tim Dillard, RHP — I don’t necessarily care for his stuff, but he can be good.

Hiram Burgos, RHP — The starting rotation is in disarray anyways, so why not try out one of Milwaukee’s top pitcher-of-the-year candidates a few times?

Fautino De Los Santos, RHP — Melvin might as well see what he got in return for Kottaras.

Mitch Stetter, LHP — Why not recall a southpaw reliever?

Edwin Maysonet, SS — Is it possible to have too many shortstops on this roster? There is a limit, but it has yet to be reached even with Maysonet.

Eric Farris, 2B — Elite speed could be utilized on the bases and, hey, maybe he shows he can hit at a mediocre level after all.

Ariel Pena, RHP — Like Hellweg, Pena has back-line starter material and has performed well thus far in double-A. Might as well see how he fairs against big-league hitting, right?
