DENVER -- Rockies lefty Tyler Anderson could be activated for his next start, after one injury rehab appearance, while righty Jon Gray has made two rehab appearances, but will need another, Rockies manager Bud Black said Tuesday.
Anderson (3-5, 5.85 ERA), who is on the 10-day disabled list with left knee inflammation, last pitched in the Majors on May 30. His one rehab appearance for Triple-A Albuquerque on Sunday -- five innings, one run, six strikeouts -- could be enough, depending on how he responds to between-starts work. He would be in line to start Friday's opener of a three-game road series with the Dodgers.
Gray (0-0, 4.38) hasn't thrown in the Majors since sustaining a navicular stress fracture of the left foot on April 13, and will make his third rehab start Saturday. Gray threw four innings Wednesday at Class A Advanced Lancaster and 4 1/3 innings Monday for Albuquerque.
"Tyler was fine," Black said. "His stuff was good. All the reports we got were fine with Tyler. Jon last pitched April 13 and he basically has thrown 8 1/3 really competitive innings over two months, and it just makes sense for Jon to pitch again."
Anderson felt much better after a few days' rest and continued his throwing program.
Anderson went 2-1 with a 2.55 ERA over four starts prior to May 30, when he couldn't push off the knee and gave up six runs and 11 hits in five innings in a home loss to the Mariners. Sunday's Triple-A start had him back to the effective fastball-changeup combination, with curveballs and cutters mixed in.
"I didn't have one issue with the knee, so that's definitely a step in the right direction," Anderson said. "I used the whole repertoire."
In his start Monday, Gray struck out seven, but gave up five runs, including two homers, in 4 1/3 innings. Just one of the runs was earned.
"I never felt like I was in trouble; I felt in control the whole time," Gray said. "I'm kind of glad that stuff happened in the field. I needed that -- the stress point of a start. There's always a time when you've got to make a pitch to get out of it."
Worth noting
• Rockies third baseman Nolan Arenado arrived at the park to see a display dedicated to his otherworldly performance on Sunday, when he celebrated Father's Day with a cycle that included the first walk-off, cycle-completing home run with the batter's team behind in Major League history.
Arenado's jersey -- complete with the blood that ran from his face when he was clipped above the left eye by Charlie Blackmon's batting helmet during the celebration -- was behind glass, along with the lineup card, pictures and other artifacts in the Coors Clubhouse premium area.

"I was happy to have the day off yesterday," Arenado said. "I could really enjoy it, too. I've moved on and I'm ready for today.
"I enjoyed it for a couple hours, seen the video thousands of times. I'm ready to get going."
