HOUSTON, Texas -- The Houston Astros are finalizing a deal to acquire center fielder Daulton Varsho from the Toronto Blue Jays, sources told ESPN's Jeff Passan on Monday.

Toronto reportedly would get right-hander Spencer Arrighetti in return, pending physicals for both players.

The Astros, who have been trying to find a left-handed hitting outfielder for years, have been one of the hottest teams in baseball, winning 11 of their last 12 games to surge into first place in the American League West.
