Sosa is expected to come off the disabled list and be in the starting lineup when the Orioles open a three-game series with the visiting Seattle Mariners.
Sosa has been out since May 4 due to a staph infection on the bottom of his left foot. Acquired in the offseason after 13 seasons with the Chicago Cubs, Sosa is batting .269 with four homers and 13 RBIs.
“Right now we’re looking at Tuesday,” Orioles manager Lee Mazzilli said Sunday. “He hit yesterday, and it seemed like he didn’t lose a beat. He swung the bat well, hit some balls in the outfield, so we’re going to target Tuesday and see what happens.”
Sosa is eager to get back on the field.
“Everything feels great,” he said. “For the past couple of days, I have been hitting and it feels great. It’s still a little bit sensitive, but I can deal with that.”
The Orioles have dropped three of four following a four-game winning streak, including Sunday’s 7-2 loss to Philadelphia. Miguel Tejada hit his 11th homer for Baltimore, which leads Boston by two games in the AL East.
The Mariners are coming off their first shutout of the season, a 5-0 win over San Diego on Sunday. Aaron Sele threw a four-hitter and Jeremy Reed had three hits and two RBIs for Seattle, which finished above .500 on a homestand (5-4) for the first time since July.
“I think today was more indicative of the type of club that we have,” manager Mike Hargrove said.
