Marrero went 7-for-17 (.412) with two doubles, one homer and four RBIs in six games with low Single-A Hagerstown and high Single-A Potomac. He has recovered from a torn hamstring suffered in winter ball, as well as a sore shoulder and now a bruised thumb.
Mattheus has been battling back from a nagging plantar fasciitis issue in his left foot. Mattheus took the loss in his first minor league rehab Sunday at Potomac, allowing two home runs.
Kobernus has been on the disabled list with a thumb injury. He has hit ,281 with seven doubles, one homer and seven RBIs in 43 games.
Manager Matt Lecroy told me a few weeks ago he was looking forward to getting Kobernus back in the lineup.
“He has had a solid year so far,” Lecroy said of Kobernus. “The way he prepares every day for each game is just showing his maturity as a player. Hopefully, when we get him back, he can get going.”
