9:10pm: The trade is official, as per a Blue Jays media release.
8:43pm: Schulman tweets that an official announcement is coming soon. He notes that Lewis has updated his Facebook page to say that he's going to the Jays.
7:49pm: According to Henry Schulman of the San Francisco Chronicle, he is hearing "strong indications from multiple sources" that the Giants are trying to finalize a trade that would send outfielder Fred Lewis to Toronto. Schulman doesn't know as of yet what San Francisco will get in return.
Andrew Baggarly of The San Jose Mercury News reported on Tuesday that Toronto was "the most likely destination" for Lewis, who had become expendable in San Fran given their glut of outfielders. Lewis is out of options, and since his minor league rehab stint was up today, the Giants had to either expose him to waivers or work out a trade. Earlier tonight, Schulman passed on a report from Fresno Grizzlies radio broadcaster Doug Greenwald (via Twitter) that Lewis wasn't in the lineup for the Giants' Triple-A affiliate, leading to speculation that a deal could be forthcoming.
Lewis has a career 4.8 UZR/150 as an outfielder, and that rating jumps to 10.2 as a left fielder (though it plummets well below average in CF and RF, albeit in a much smaller sample size). Toronto would likely use him primarily as a late-inning defensive replacement in the outfield and a pinch-runner. Given Lewis' .805 OPS in 838 career plate appearances against right-handed pitching, though, Lewis could also take some playing time away from starting right fielder Jose Bautista, who has just a .225/.316/.364 career line against righties.
