LAD@COL: Masset leaves game with a left knee injury

DENVER -- Right-hander Nick Masset will test his sprained left knee Saturday by pitching off a slope with the hopes of throwing a bullpen session Sunday if all goes well.

Masset's injury occurred while covering the plate on a passed ball in the seventh inning of last Saturday's 8-7 victory over the Dodgers. His MRI revealed a left patellar tendon strain after the Rockies had initially feared a tear.

Masset is eligible to come off the disabled list on July 21 but will likely require a rehab assignment.

Masset had proven to be one of the Rockies more reliable relievers before he surrendered four earned runs without recording an out during the outing in which injury occurred. By the time that Masset was helped off by a trainer, his ERA had inflated from 3.42 to 4.94.

Overall, Masset has compiled 18 strikeouts against 26 hits and 12 walks across 23 2/3 innings for the Rockies this season.

Butler to make first rehab start Saturday

LAD@COL: Butler records his first career strikeout

DENVER -- Rockies right-hander Eddie Butler will make his first rehab assignment Saturday with Class A Advanced Modesto as he works his way back from right rotator cuff inflammation.

Butler is set to throw 60 pitches in Modesto against Bakersfield following his successful 45-pitch simulated game session on Tuesday.

The Rockies want Butler to make at least two rehab starts with the second coming on July 17 for Triple-A Colorado Springs. He's tentatively scheduled for 75-80 pitches that day. If all goes well, he would be in line to start again on July 22, which is when the Rockies first require a fifth starter out of the All-Star Break.

Butler has been out since feeling an unusual level of soreness in his throwing shoulder after his Major League debut on June 6. He's also been battling a blood blister that first appeared on July 5 during his live batting practice session against Carlos Gonzalez.

Butler expects the blood blister to be a "constant thing" but he's continually had it drained and hasn't missed any of his rehab steps while dealing with it.

The Dodgers got to Butler for 10 hits and six earned runs across 5 1/3 innings during his Major League debut last month. Before that, Butler held a 2.62 ERA across 68 2/3 innings at Double-A Tulsa with 40 strikeouts against 19 walks.

Lyles fields grounders, gets set for rehab assignment

ARI@COL: Lyles fractures hand on play at the plate

DENVER -- Rockies right-hander Jordan Lyles (fractured non-throwing hand) will begin his rehab assignment on July 18 with Double-A Tulsa following Friday's successful live batting practice session

The Rockies are looking for Lyles to make three rehab starts total, with his next two coming on July 23 and 28. But if he shows the team enough in the first two, Lyles' third start will be with the big league club, similar to what the Rockies are planning to do with left-hander Brett Anderson this Sunday.

Anderson was set for three rehab starts as well, but he'll be starting for the Rockies on Sunday with a pitch count around 85. Lyles would likely follow a similar plan if the Rockies decide to call him up against Cubs in Chicago on July 28.

Lyles fielded grounders and received the ball with his glove hand Friday for the first time since fracturing his left third metacarpal while covering a play at the plate on June 4.

"Jordan looked good," manager Walt Weiss said. "The problem with Jordan is not so much the ball going to the plate, it's the one coming back at him with a broken hand. His arm is in good shape, the hand is healing well and he's getting ready to go out here soon."

Lyles compiled a 3.52 ERA and a 5-1 record in 11 starts with the Rockies before breaking his left hand on a home-plate collision with the D-backs' Martin Prado in early June. Lyles had totaled 40 strikeouts against 63 hits and 19 walks across 68 2/3 innings after the Rockies acquired him and outfielder Brandon Barnes from the Astros for outfielder Dexter Fowler last offseason.

CarGo returns to Rockies after finger surgery

COL@CLE: CarGo hammers a two-run homer to center

DENVER -- With outfielder Carlos Gonzalez making his return from left index finger surgery on Friday, Rockies manager Walt Weiss will be getting "a very dangerous bat" back in the middle of his lineup.

Gonzalez batted third and played right field against the Twins after the Rockies optioned right-hander Jair Jurrjens to Triple-A and activated the two-time All-Star on Friday. Weiss expects to see a more confident Gonzalez this time around now that he doesn't have to deal with any swelling in his finger after having a benign tumor removed from it on June 10.

"I think he's got some peace of mind with that finger," Weiss said. "First couple months, that finger was blowing up, sometimes for no rhyme or reason."

Being out since June 4 also allowed Gonzalez to make progress on another injury front.

"The time off has certainly helped his knee [tendinitis]," Weiss said. "That's been something that's hindered him from time-to-time over the last couple of years."

Gonzalez made 48 starts in left field before being placed on the DL, but Weiss confirmed that he'll now be the starting right fielder "for the foreseeable future." Gonzalez's move to the opposite corner stems from Weiss' desire to keep Corey Dickerson's bat in the lineup.

Dickerson was batting .327 with 37 runs but remained out of the lineup Friday as he works his way back from a wrist injury.

Dickerson was feeling "much better" after spraining his wrist on a diving attempt during the ninth inning of Tuesday's 2-1 win over the Padres. Weiss said Dickerson has made "a lot of improvement" after getting the past two days off and will be available to pinch-hit Friday with Drew Stubbs getting the start against a left-hander.
