Sanchez (biceps) will begin his rehab assignment Monday, Pete Caldera of the Bergen Record reports.
Sanchez opened the season by playing just five games before being placed on the disabled list with a bicep strain. Over that brief span he went 3-for-20 (.150). To this point he's gradually increased his level of activity and recently began participating in batting practice. Although the team has yet to provide a specific timeframe for his return, it would seem that an early-May activation from the DL would be obtainable if his upcoming rehab assignment goes smoothly.
