Showalter on Tillman, Miley, Trumbo, Davis and Wieters (O's up 4-0)

The Orioles are playing their 2,000th game today at Camden Yards, which also marks Chris Tillman's return to a major league mound after starting the season on the disabled list with right shoulder bursitis.

Tillman will be evaluated by today's performance, of course, but also how his shoulder responds in the ensuing days.

"You know when he's feeling good about himself and his stuff, but there's another part of that after today," said manager Buck Showalter. "It's a long season for pitchers and the things they have to do. Amazes me when guys make start after start after start.

"Once again, the other team's going to tell us how he's doing. I'd love to see the command, that type of stuff."

Wade Miley's left wrist appears to be fine after a line drive in Friday's game left him with a nasty bruise. He's listed as Wednesday night's starter in D.C.

"When I left, he was in the whirlpool. Or his wrist was," Showalter said. "He seemed to be in pretty good spirits. Of course, he is all the time."

The Orioles have been waiting for Mark Trumbo and Chris Davis to heat up. Trumbo has two home runs after leading the majors with 47 last season, and Davis has hit four home runs with seven RBIs. But Trumbo is 6-for-12 in his last three games and has four two-hit games this month. Davis hadn't homered since April 14 before connecting Friday night, and is 6-for-14 in his last four games.

"I trust the track record," Showalter said. "That's what everybody's trying to develop here, so you stick with them through the times when they don't perform at the level they spoil you with and will again. Sometimes it doesn't happen, but these two guys, I watch their work habits and their want-to. It's there. We know it is. And it usually comes to the forefront.

"It's so funny, because all of a sudden they'll have a good game or two and everybody says, 'Oh, it's going to explode.' And then Chris Sale pitches. You look at the pitching we faced the first month-plus. We're going to see (Max) Scherzer and (Stephen) Strasburg and Gio Gonzalez against Washington. It seems like a who's who of pitching. That's one reason why I'm proud of our pitching. You have to match them or at least keep you in the game.

"They've got some big hits for us. On one side it makes you trust them because they've done it before. But they get frustrated because they know what they're capable of. Can you imagine having that type of power at your fingertips and not being able to get to it every time you swing the bat? That's got to be so frustrating. I've never had that feeling, the type of power Chris and Mark have. They have the ability to do other things, too. That's what Scott (Coolbaugh) stays on them about. The other things will come. Just stay true to ... They both have a good routine."

Matt Wieters' routine will be disrupted Monday afternoon when he meets with the local media to discuss his return to Camden Yards after signing with the Nationals. It won't be a typical day for him.

"It's kind of like Miguel (Gonzalez)," Showalter said. "We had the perfect scenario the other night. Miguel pitched well and we won. If you could draw it up, that's the way I would have drawn it up.

"You know what? I'm so focused right now I hadn't really ... It's crossed your mind. I think he's doing well, right? It doesn't surprise anybody. Fully expected. It's kind of good that some different people other than us get to see what Matt brings. I'm sure he's one of the reasons why they're off to such a great start. Obviously, they've got a really good pitching staff. I think a lot of Dusty (Baker).

"Matt is solid. One of those things that, that's how the game works. We did some things to try to keep him. Signed him, evaluated him, liked him, drafted him. Everything. When you've got a guy who grew up in the organization and is somewhere else, you know all about him. There's so much to like about Matt."

Wieters has appeared in 24 games this season and is batting .274/.365/.476 with five doubles, four home runs and 12 RBIs. He's thrown out three of 15 runners attempting to steal.

"Matt gave a lot of things to us, and we gave a lot of things to Matt," Showalter said. "Matt's very adaptable to a different environment. He helps create them, too. He helped create some things here for us."

Update: Chris Tillman escaped a bases-loaded, one-out jam in the top of the first and the Orioles scored twice after loading the bases with one out in the bottom half. Chris Davis had a sacrifice fly and Trey Mancini punched an RBI single into right field.

Update II: The Orioles also scored twice in the second inning, on RBI singles by Adam Jones and Manny Machado. Jones hit a blooper down the right field line after fouling a ball off his left shin.

Jose Quintana has thrown 60 pitches in two innings.
