Chavez completed his injury-rehab assignment tonight at Single-A Delmarva, going 0-for-1 with two walks and a run scored.
Catcher Taylor Teagarden, who went 1-for-3 tonight with a double, RBI and walk, is expected to be activated from the 60-day disabled list tomorrow. Catcher Ronny Paulino could be designated for assignment to clear room on the 25- and 40-man rosters.
