ST. LOUIS -- D-backs outfielder Steven Souza Jr. continues to make progress in his rehabilitation from a strained right pectoral muscle, and if all goes well, it's possible he could return to the team toward the end of this nine-game road trip or the beginning of the next homestand.
Souza played catch from 135 feet Thursday at the team's Salt River Fields facility in Scottsdale, Ariz. He also hit on the field during batting practice there.
"So we need to see BP for a couple more days, and we should see game progression after that," general manager Mike Hazen said. "So a couple more days of BP at least, and again, making sure he hits all his markers, and then we'll be talking about games behind that."
After he gets enough batting-practice sessions, Souza will need to play in some games to get his timing down at the plate. How many games will depend on how quick that progression is.
Souza injured his pec while diving for a ball in a Cactus League game on March 21 against the Giants.
In other injury news, third baseman Jake Lamb, who suffered a sprained left AC joint when he dove for a popup Monday night against the Dodgers, is also back at the team's Spring Training facility.

Lamb still has soreness, and until that dissipates, he won't be doing any baseball activity.
The team has not said what kind of timetable Lamb has for a return, and it won't have a firm idea of that until the soreness goes away and he starts activity.
"I still don't anticipate it being on the longer end," Hazen said. "But we'll see how it goes."

Shortstop Nick Ahmed was out of the lineup for the third straight game Thursday as he recovers from flu-like symptoms.
"He's much better," manager Torey Lovullo said. "He flew with us [Wednesday] night, he was available [Wednesday] in an emergency status and he's recovered 24 more hours. He's not in the lineup today because I wanted to see him come out and get some functional testing, just test his own boundaries and see where he's at. I know he'll be available for us, I just want to know at what level."
