Arenado proud of younger bro, drafted by Giants

DENVER -- Rockies third baseman Nolan Arenado expressed pride in his younger brother, Jonah, who was selected by the Giants in the 16th round of the MLB First-Year Player Draft out of El Toro High School in Lake Forest, Calif.

"I talked to him and he's excited," Arenado said. "He thought he was going to go a little bit earlier, but he's really happy. He's worked really hard. A couple years ago, I didn't know if he was even going to play at a junior college, and he didn't know if he wanted to play baseball, but he's worked hard, and to be drafted is pretty exciting.

"He's put in the hard work. It's all on him. I can only do so much. He did what he had to do, got bigger and stronger, got quicker and got a lot better with the bat."

Nolan Arenado said Jonah Arenado is about 6-3 with a powerful build. Jonah has played shortstop but projects as a corner infielder.

"He's talking to some schools, but I think he really wants to go play some ball, so if the deal is right, he's going to go out there and play some ball," Arenado said.

Escalona exits game with triceps issue, MRI Monday

DENVER -- Rockies right-handed reliever Edgmer Escalona left Sunday's 8-7 win over the Padres in the seventh inning with right triceps soreness and will have a precautionary MRI Monday.

Escalona exited the game after delivering back-to-back home runs to Cameron Maybin and Mark Kotsay, handing San Diego a one-run lead.

"It looks like his elbow," Rockies manager Walt Weiss said. "It's been bothering him off and on, but he was good to go today. He was good to go more than one [inning] today. But that was bothering a week and a half or so ago. It started bothering him a little bit."

Escalona's ERA climbed to 4.18 after he surrendered three runs in just one-third of an inning.

Colvin confident that he belongs in big leagues

DENVER -- The Rockies' left-handed-hitting Tyler Colvin felt he belonged in the Majors, even when he struggled mightily with his swing during Spring Training, and especially when the club sent him to Triple-A Colorado Springs to start the year. He never lost the feeling when he was passed over for a callup several times.

Colvin confirmed his belief during Saturday's 4-2 loss to the Padres. Colvin drove in a run with a productive groundout. But it was hit final at-bat -- a line drive that Padres second baseman Jedd Gyorko snagged, preventing a possible two-run single -- that let him know for sure.

"You can't ask for anything more than to have the tying run on second base in your second at-bat back up," said Colvin, who plays all three outfield positions and first base. "I hit something hard, and I was like, 'This is where I'm supposed to be.'"

The demotion was jarring. Colvin batted .290 with 18 home runs and 72 RBIs last season, his first with the Rockies after being acquired in a December 2011 trade with the Cubs. During the offseason, he avoided arbitration by signing a one-year, $2.28 million contract. But he hit .167 with two doubles this spring and found himself in Triple-A.

Colvin hit .293 with nine home runs, eight doubles, four triples and 29 RBIs in 55 games at Colorado Springs.

"In everyone's career, they realize this is a business, and that was one of those times," Colvin said. "I was a little upset, obviously. Who wouldn't be? But once you realize this is a business, you've got to go out there and play and wait your turn.

"Honestly, it didn't take my swing long at all. Once I started playing games, there it was. A couple of times, I tried a couple of things that didn't work out. Besides that, it was just all timing."

Chatwood aims to return to the mound Friday

DENVER -- The Rockies starting rotation could return to full strength by Friday, when right-hander Tyler Chatwood said he hopes to return to the mound.

Chatwood tossed his first bullpen session Saturday since leaving a start against the Reds on Monday after pitching four innings with soreness in his right triceps. He is scheduled for another session Tuesday, when he will likely throw to live batters.

Barring a setback, Chatwood said he should be the Rockies' starter Friday against the Phillies at Coors Field.

"I think that's the schedule so far," Chatwood said. "So if all goes well, I think that's the day I'll be throwing."

Colorado does not have a clear starter penciled in for Thursday, so there's also a chance that he returns earlier.

After starting the year with Triple-A Colorado Springs, Chatwood has a 2.14 ERA and 3-1 record through six starts. The 23-year-old was a perfect 2-0 with a 1.53 ERA in May before picking up his first loss of the year in his lone June start against the Reds. He surrendered just one earned run in Cincinnati before leaving the game.

Betancourt playing catch as rehab progresses

DENVER -- Injured Rockies closer Rafael Betancourt said this week will be significant in his recovery from a right groin injury that forced him to the disabled list on June 2. He is eligible to return on June 16.

Betancourt underwent platelet-rich plasma (PRP) treatments on Monday and Friday to aid in healing, and he planned to do underwater exercises and play catch on Sunday.

"The good thing about it is the soreness that I had when I was pitching, I don't feel that," Betancourt said. "I didn't do anything for a week. Man, it's not fun, but maybe that helped.

"This week is going to be very important, too. I'll start doing a lot of moving and see how my legs will react. Hopefully, I won't have any soreness. If that happens, I'm going to be fine. That's what I want."

Betancourt has dealt with soreness since 2009, when he underwent surgery to repair a torn groin muscle. The soreness is around the scar tissue. He usually pitches through it, but this year it became impossible.

Betancourt converted 10 saves before being removed after two pitches on May 21 because of the pain in his leg. On May 25, he blew a save at San Francisco, converted a save at Houston on the 28th, and on the 31st, he entered a tie game at home against the Dodgers and took the loss.

"To say this was the worst, I don't know, but it was different," Betancourt said. "The soreness I had the next day after throwing, I never had that before. That's what took me out. I couldn't hold up anymore. Every time I got to the ballpark, I was thinking more about that than going out to pitch. You have to think about pitching, then other stuff. But it happened.

"After ... all the work I put in during the offseason and during the season, I was really mad that this happened. But there's nothing I can do about it. I wasn't helping the team the way I was supposed to. I don't think it's fair for the guys to go play the whole game, and I come in for one inning and blow everything out. It's not a good feeling, especially when you know you're not completely 100 percent."

Rox hoping that Cuddyer can return this week

DENVER -- After missing his third consecutive game Sunday -- an 8-7 win over the Padres -- right fielder Michael Cuddyer said he is hopeful that the team's day off Monday will allow him to return to the lineup Tuesday.

Cuddyer has been one of the Rockies most productive and dependable bats this year. He was hitting .339 with 10 homers and 37 RBIs before he suffered a rib strain in Thursday night's loss to the Padres. The injury occurred when he ran out a ground ball for the final out of the game, colliding with the Padres' first baseman and landing on the ground with his elbow pushed into his upper rib cage.

"He had a bunch of treatment today, he had another day off tomorrow and we're hoping for Tuesday," Rockies manager Walt Weiss said Sunday.

Usually hitting from the No. 5 spot, Cuddyer has acted as the third piece to Colorado's lethal 3-4 duo of Carlos Gonzalez and Troy Tulowitzki, so it comes as welcome news for Rockies fans that Cuddyer should not be out for an extended period.

"We still feel fairly confident that we won't have to DL him," Weiss said.

Weiss also said there is no correlation between Cuddyer's rib strain and the oblique strain that knocked him out for the final third of last season. He suffered the injury at the end of July and played only three more games in 2012.
