Well, all this Roy Halladay talk is becoming OFFICIAL, finally. Halladay is going to the Philadelphia Phillies; Cliff Lee is going to the Seattle Mariners; and a slew of prospects are being shipped all across the continental United States.

A complete recap of the deal, most of which is courtesy of the Philadelphia Daily News:

Philadelphia Phillies receive:
Halladay and cash from Toronto
RHP Phillippe Aumont from Seattle
RHP Juan Ramirez from Seattle
OF Tyson Gillies from Seattle

Toronto Blue Jays receive:
RHP Kyle Drabek from Philadelphia
C Travis d’Arnaud from Philadelphia
INF Brett Wallace from Oakland

Seattle Mariners receive:
LHP Cliff Lee from Philadelphia

Oakland Athletics receive:
OF Michael Taylor from Philadelphia by way of Toronto

We talked a little about the fantasy impact of Halladay and Lee, the two known Major League commodities changing locales. The next two most relevant names, in terms of possible 2010 impact, are Wallace and Taylor, whom the A’s and Blue Jays swapped in a corresponding deal.

Wallace is Major League-ready, and he could have a starting job in Toronto on Opening Day. He joins forces with OF Adam Lind and OF/DH Travis Snider to form a young nucleus of natural, polished hitters to propel the Blue Jays into the future. Wallace has the skill set to compete for batting titles, though he may or may not hit for enough power to make a difference in fantasy.

Toronto will be Wallace’s third organization in two seasons after being sent from St. Louis to Oakland last July as part of the Matt Holliday deal. His star hasn’t faded in any way, though, and he gets a chance to prove his worth North of the border.

Keep an eye on him as a late draft choice or early waiver wire selection, depending on how he fares during spring training. For that kind of low-cost flier, the potential rewards far out-weigh the risks.

A move to Oakland helps accelerate Taylor’s timetable for a Major League debut. The Athletics have one of the deepest commitments in baseball to letting their young players play, and Taylor could get that chance quickly.

The soon-to-be 24-year-old hit .320 between stops at Double-A Reading and Triple-A Lehigh Valley, with 20 home runs, 84 RBIs, 74 runs and 21 stolen bases. Taylor stands at 6-foot-6, 250 pounds and is physically, and in terms of maturity, ready for the big show.

General manager Billy Beane needed a high-upside, physically gifted player in his outfield mix in the worst way, and he got just that in Taylor.

There are nine outfielders currently listed on the team’s 40-man roster (not including Taylor), and it’s hard to find a surefire everyday player among them. The opportunity is there for Taylor, and he has the type of roto potential that warrants a good, long look this spring. He could make the big league club out of camp.

Oakland A’s blog Talkin’ Dirt gives the Taylor-for-Wallace trade a couple of thumps up:

“With the addition of Taylor and Chris Carter in AAA people are talking about ‘Bash Brothers Part II.’”

Baseball America offers a quick profile on Taylor:

“The 24-year-old Stanford alumnus has shown five-tool ability with excellent size at 6-foot-6, 250 pounds. He runs well for his size. Taylor hit a combined .334 with 39 home runs and 36 stolen bases the last two seasons, working his way up through four stops from low Class A through Triple-A. … Scouts’ biggest knocks on him are for his defense, which fits better in left, and his power, which is only slightly above-average and a bit short for a true left fielder’s profile. His swing has been more oriented for contact despite his size, but it’s hard to argue with the results.”
