BALTIMORE — Injured second baseman Brian Roberts hadn’t been spotted in the Orioles clubhouse since early April when he was placed on the disabled list with a right hamstring injury, but the 35-year-old is glad to be home.

Even if he’s still a few weeks away from a potential return to major league action.

After rejoining the club during its three-game series against Tampa Bay over the weekend, Roberts has elected to continue his rehabilitation efforts in Baltimore after spending most of the last two months in Sarasota. The 35-year-old underwent surgery less than five weeks ago and described himself as being in the “home stretch” of the recovery process before going on a minor-league rehab assignment.

“It’s great to be back,” Roberts said. “You feel kind of isolated on an island down there. It is already good to be around the guys and feel like you are part of the team.”

Roberts has increased his activity level over the last couple weeks as he is taking batting practice, playing catch, and continuing to test his surgically-repaired hamstring as he works his way back to running at full speed. Roberts reiterated Monday what he said over the weekend about not anticipating a lengthy rehab assignment like the one he completed last year while returning from concussion-like symptoms.

Manager Buck Showalter seemed to agree with that assessment as long as Roberts felt he was ready, mentioning three to seven games as possible estimate. Meanwhile, Roberts is focused on testing the hamstring to make sure it’s 100 percent before he takes the next step of playing in minor-league games.

“Mainly the running progression,” Roberts said. “Just continuing to build up to where you can be explosive again [and] where you can cut, you can stop, you can backpedal. The running has really taken some good steps forward in the last couple of days and I’m hoping that is a sign we have reached the point where things can started moving a little quicker.”

Roberts hasn’t played since injuring his hamstring in St. Petersburg on April 4 and is fully aware of the doubts expressed over his ability to remain healthy as the Orioles have struggled to find production at second base with the combination of Ryan Flaherty and Alexi Casilla. The veteran infielder has played in just 118 games over the last four seasons combined.

For now, he’s happy to be back in a big-league environment while in the midst of the final year of a four-year, $40 million that obviously hasn’t worked out how either side had hoped.

“Nothing compares to being in this atmosphere,” Roberts said. “I don’t know how much longer I have left to be in it, and I want to be around it as much as possible.”

NOTES: Right-handed pitcher Dylan Bundy began a throwing progression in Sarasota on Monday, completing 25 throws from 60 feet without experiencing any discomfort, according to Showalter. … Outfielder Nolan Reimold (hamstring) could be ready to go on a minor-league rehab assignment by the end of the current homestand. Showalter offered a similar range of games for Reimold as he spelled out for Roberts. … Left-handed pitcher Wei-Yin Chen will be summoned to Baltimore as soon as he’s ready to begin throwing off a mound, according to Showalter, which should be in the not-too-distant future barring any setbacks. …Casilla was not in the starting lineup after jamming his right index finger sliding into second base on Sunday. Showalter revealed that he likely would have started Casilla against the Angels after the utility infielder went 2-for-3 with two RBIs in the series finale against the Rays.
