"Everything's just play it by ear at this point to see how the arm reacts and how I feel," McHugh said. "I felt good. The body feels good. We're going to monitor how my body reacts to it and go from there. We haven't really put together a timetable of when we really want to ramp it or when we want to be on the mound by or when we want to play on games by. Hopefully this is a good sign of things to come."
McHugh was placed on the DL late in the spring with right shoulder tendinitis and then left his first rehab start in the season opener at Triple-A Fresno on April 6 because of discomfort in his elbow. He came down with arm fatigue early in spring camp and had worked his way into a game, throwing 1 2/3 innings against the Cardinals on March 27 in his only Grapefruit League appearance.
"You get a ball in your hand again and do the thing that you're getting paid to do, at least to a small extent," McHugh said. "It feels good. Obviously, it's going to be a slow process, but hopefully we're headed in the right direction."
• Right-handed reliever Jandel Gustave, who's been on the disabled list since April 19 with right forearm tightness, was sent back to Houston on Friday to be examined by team doctors after a live bullpen session Thursday at Triple-A Fresno saw him suffering recurring arm soreness.
"He's no longer trending towards a rehab assignment," Hinch said. "He was. He threw a live BP in anticipation of going on a rehab assignment."
• Outfielder Teoscar Hernandez, who suffered a lower leg bruise in a collision with Jose Altuve in Cleveland 10 days ago, is in Fresno working toward a rehab assignment, Hinch said.
