Astros righthander Lucas Harrell, who skipped his previous scheduled start because of a right groin injury, is ready to get back on the mound Saturday night when the Astros visit the Washington Nationals. “It’s great because my leg feels great and my body feels great,” he said. “We were just cautious. It wasn’t anything that we thought there was something serious. “It’s just something that was small and we wanted to make sure that I was right before we broke camp.” Although most of the starters are building toward throwing 75 pitches and four or five innings per outing, Harrell isn’t scheduled for any specific goal. “He’s kind of set back a little bit,” manager Bo Porter said. “We’re going to just basically take it inning by inning and see what his pitch count is and then make a decision as the game presents itself. “He’s had some good side sessions, but at the same time he missed a turn, but we will lean on the side of being careful.”
