mlb 09/04/07 6:15 PM ET Jonathan Mayo is a reporter for ]]> With that in mind, we're tossing the usual Futures Exchange format out the window.

This week, we're going to look only at players "in the bigs," breaking down who got called up and why, who's going to play and perhaps help you in 2007, and who might be worth a look in 2008 and beyond.

One note: Just because you don't see a player listed here or on transactions doesn't mean he won't get called up. The Minor League season, in most cases, didn't end until Monday, so you won't see some official callups happen until Tuesday (the first one listed below wasn't actually on the transaction wire when I wrote this). Then you have some teams that are playoff-bound in the Minors. Major League organizations likely won't call up some prospects on these teams until the postseason is over (see Sacramento in the A's system).

Boston Red Sox: Recalled RHP Clay Buchholz, LHP Craig Breslow, OF Jacoby Ellsbury and OF Brandon Moss from Triple-A Pawtucket.

Hmmm, I wonder if this one will work out at all. Now that Buchholz has tossed a no-no in a spot start for Tim Wakefield (who's expected back), it seems that it's unclear what will happen next. Buchholz has thrown 140 1/3 innings this season. According to reports, he hasn't quite hit his threshold -- maybe 150 IP? If so, he might sneak in another start or two, in which case you'll want to know when that is and pick him up. He could provide some bullpen support, but that won't help you now. Either way, pencil in this guy for a rotation spot in 2008.

I've been pushing for Ellsbury to get playing time in the big leagues for a while now, and he'll get some as long as Manny Ramirez is out. Since being recalled, he's gone 5-for-9 with a homer, four runs scored and a steal. Don't expect power, but as long as Manny is sidelined, Ellsbury's worth putting into your lineup, regardless of format.

Seattle Mariners: Recalled OF Wladimir Balentien and selected the contract of C Jeff Clement from Triple-A Tacoma.

In the heat of the American League Wild Card race, it's unclear how much either of these guys will play. Clement could see some ABs behind the plate and/or at DH, but probably not enough to warrant putting him in an active lineup right now. But at the end of this season, he certainly looked like the hitter most were expecting to see when the Mariners took him with the third overall pick in 2005. He hit .333 and slugged .552 in August while driving in 24 runs. For the year, he finished with 20 homers and 80 RBIs, the kind of numbers from a catcher that would make most fantasy owners quite happy. Whether he ever actually plays that position for Seattle remains to be seen, but he should at least be on your watch list for keeper candidates.

I must admit, Balentien intrigues me. He's got power (24 HR, .509 SLG), and he's got some speed (15 SB). He also has a history of being an all-or-nothing hitter, though it should be noted that his K rate went way down in 2007. He won't help you now, and it's hard to see how he could sneak into the Mariners' outfield in 2008, so keep an eye out to see if he can be freed via trade.

Washington Nationals: Selected the contracts of LHP Ross Detwiler, OF Justin Maxwell, RHP Jonathan Albaladejo, LHP Arnie Munoz and OF Ryan Langerhans.

The most interesting names here are the first two. Detwiler was the Nationals' No. 1 pick in this June's draft. He has just over 33 innings of professional experience under his belt, none of it above A ball. The lefty will likely just watch and learn and won't help you out in 2007 at all. This taste could help fast track him to the bigs by 2008, though I still think it'll be 2009 before he has a really positive fantasy impact.

Maxwell also hasn't played above A ball, but he has some exciting five-tool skills. He stole 35 bases and hit 27 homers in the Minors this year, but he's going to do little other than pinch run and play some defense in this final month. I have to think he's still two years away from being ready for this full time.

Kansas City Royals: Purchased the contracts of 1B Craig Brazell and C Paul Phillips from Triple-A Omaha, recalled RHP Luke Hochevar and 1B Justin Huber from Omaha.

While Brazell led the Minors in home runs and had a fantastic year, it's hard to see him playing much down the stretch. Ditto for Huber. Still, he might be a nice AL-only option in 2008, depending on how the roster shakes out.

The guy who really intrigues is Hochevar, the No. 1 overall pick from 2006. He had a Major League contract, so he was already on the 40-man roster. His overall numbers won't excite you -- 4-9, 4.86 ERA -- but he finished the season extremely well, allowing eight runs in 25 innings over his final four starts. That's a 2.88 ERA for those of you scoring at home, and he struck out 22 while waking seven in that span. The plan is to have him pitch out of the 'pen the rest of this year unless something happens in the rotation. Even so, he'd be a bit risky for this year, but the callup does mean he could get a shot to compete for the rotation to start 2008.

Pittsburgh Pirates: Recalled RHP Bryan Bullington, RHP John Van Benschoten and LHP Dave Davidson.

Nothing earth-shattering here, though it's not often that two first-round picks, both pitchers, get called up at the same time. If you're in an NL-only league and you're absolutely desperate, Bullington is likely going to start on Wednesday in St. Louis.

Los Angeles Dodgers: Recalled 3B Andy LaRoche from Triple-A Las Vegas.

Normally, a callup like this for a team in the thick of a playoff race wouldn't be worth mentioning. But now that it appears LaRoche is healthy, he's going to play. He missed some time with back issues, but appears to be as close to 100 percent as he's been all year. His Triple-A numbers are impressive: .309/.399/.589. He's gone just 1-for-7 in his first two games back up, though he drove in a pair on Monday and continues to show he knows how to get on base. Even if Nomar gets activated, he'll only pinch-hit for the time being, so look for LaRoche to get most of the time at third. NL-only owners should take a shot and anyone in a keeper league who hasn't already done so should pick him up. This guy should be the third baseman in Los Angeles on Opening Day 2008, assuming he's healthy.

Minnesota Twins: Recalled RHP Kevin Slowey and selected the contract of RHP Nick Blackburn from Triple-A Rochester.

Slowey, the International League Pitcher of the Year after finishing with a 1.89 ERA in 20 Triple-A starts, is back and the Twins are giving him the ball right away. He starts Tuesday night against the Indians. While he won three games during his earlier stint with Minnesota, his command was off and he had trouble making some adjustments. Don't expect that to happen again. This is a smart pitcher who learns from his successes and failures. I see him putting up decent numbers the rest of the way, helping out AL-only teams now at the very least and cementing a spot in the 2008 rotation. ]]>
