Before Sunday's afternoon game in Anaheim, Calif., Orioles right-hander Yovani Gallardo is scheduled to throw off a mound for the first time since going on the disabled list.
Gallardo (shoulder tendinitis) is currently still throwing off flat ground – he made 25 throws from 120 feet Wednesday and will do the same Thursday, marking the first time he has thrown on back-to-back days.
The rehabilitation schedule for Gallardo, who hasn't pitched since leaving the Orioles' April 22 game in Kansas City after two innings, is becoming clearer with a possible early June return.
"They're all part of the process and you can't jump from [one thinking], 'Oh, he'll definitely make it from this,'" Orioles manager Buck Showalter said. "I know one thing, his arm swing, the backspin with the ball, he's doing some things that he couldn't do before. I'm encouraged about this if we could stay on this schedule."
After throwing his first bullpen session Sunday, Gallardo will throw another bullpen on Tuesday and then throw a simulated game before the Orioles open a three-game series in Cleveland on May 27.
Gallardo could build his innings by throwing multiple simulated games, which Showalter said could mean he'd need no more than one or two minor league rehab starts before coming off the DL.
Need Matusz back quickly: Over a long managerial career, Showalter has learned how to deal with pitchers who have outings like Brian Matusz did Tuesday. The left-hander allowed four runs on five hits including two home runs over 1 2/3 innings in a 10-0 loss to the Seattle Mariners.
"I always say something to them," Showalter said. "I've already talked with Ubaldo [Jimenez]. We do. You try to read some things. Timing is everything. Some guys kind of want to be left alone for a little while, absorb things. It's kind of different for a reliever. He'll be right back in there."
Showalter said the team has other options against left-handed batters, and though he didn't mention names, right-hander Brad Brach is strong against lefties if they want to go another direction against Seattle.
Harvey to start throwing Tuesday: Top pitching prospect Hunter Harvey, who hasn't pitched in a game since July 2014, will begin a throwing program for the first time since having sports hernia surgery earlier this month, Showalter said.
Harvey, the Orioles' 2013 first-round draft pick, has dealt with various arm troubles plus a fractured leg that have conspired to keep him from pitching in an affiliated game since his strong full-season debut with Low-A Delmarva.
A timetable of four to six weeks was given when he had the surgery, so Harvey is still likely to make it to an affiliate by the time the season ends.
Around the horn: Orioles Hall of Famer Brooks Robinson turned 79 on Wednesday. Showalter talked about his visit with the team ahead of the 2014 playoffs, and a time when he stood in the rain on the side of the road to talk baseball with Robinson right after becoming Orioles manager. "Thank god he was born," Showalter said.
