Santana, 35, is expected to throw twice more in the bullpen before possibly having hitters track his pitches. After that, he would graduate to throwing batting practice. "If we feel good and everything is coming along, we're going to start facing hitters and building it up," he said. "After that, it's just a matter of time. We don't know how long or how many times we're going to do that until we start getting into games and hopefully able to compete. "That's the thing we don't know. We're talking about doing it one more time and if everything goes right, we're going to see if we can see some hitters, maybe some guys standing up just to see how everything is and if i can command the pitches. Then, we'll see if I can challenge them when they start swinging the bat." Santana seems to be ahead of schedule in his recovery and progression, and the two-time Cy Young Award winner could pitch sooner than the Orioles anticipated after they signed him March 4. "Put it this way: I feel good," he said. "What that means, time will tell. I feel really good. So does that mean we're going to be on the mound facing hitters soon? I don't know. But I'm optimistic when it's time that I'll be ready and we'll carry that through the season. Not just one game and one time. I want to do it the rest of the season." Showalter noted that it's a long process, but Santana is clearing "big hurdles" every day. So far, he hasn't been tripped up. "I like the fact that he's doing it and is able to come back on his work day, his start day, getting him over those hurdles," Showalter said. "He hasn't missed anything yet. You can see in his face how good he feels about it. "There's going to be another hurdle when he actually pitches in a game, but pitching in a game might be sooner than maybe he was being looked at."
