DENVER -- Left fielder Carlos Gonzalez entered Friday hitting .269 with seven homers and 25 RBIs, decent numbers for some players but below Gonzalez's All-Star norm. He went through a prolonged 7-for-54 slide that dropped his average to .234 after 24 games on April 27.
Gonzalez then went 17-for-40 in his next 11 games with six doubles, three homers, nine runs scored and 10 RBIs before going 0-for-11 last weekend at Cincinnati. Gonzalez then rebounded in a two-game series at Kansas City, going 3-for-8.
"I believe in myself," Gonzalez said. "I know that I'm going to put numbers [up]. I know that I'm going to have great games and bad games. I think it's all about your mentality. You have to stay positive and just continue to grind and try to help your team every time you have the opportunity."
During his prolonged slump, Gonzalez said his timing was off, and he swung at too many pitches out of the zone. He entered Friday with a team-leading 31 strikeouts in 156 at-bats.
Gonzalez said it's imperative to stay confident, maintain concentration and just wait for his pitch.
"I know it's hard," he said, "because after you have success in the big leagues, they're not going to throw you a cookie right down the middle so you can get out of the slump."
Arenado tossed for arguing called third strike
DENVER -- Third baseman Nolan Arenado was ejected in the eighth inning on Friday night by home plate umpire Seth Buckminster for arguing a called third strike on a 2-2 pitch.
"Obviously, I got [mad]," Arenado said. "I was just telling him, 'That's a ball. It's been a ball all night.' Then I said something like, 'That's frigging terrible.' You can put in another word. Shouldn't have said that, but I got caught up in the moment."
Buckminster is a Minor League call-up umpire. Major League Baseball is using eight more umpires this year because it has two crews in New York monitoring replays. On April 27, Buckminster ejected Daniel Murphy of the Mets for arguing a 1-2 pitch in the bottom of the 10th inning in a 7-6 loss to the Marlins.
It was the second straight game a Rockies player was ejected for disputing a called third strike. Troy Tulowitzki was ejected from the dugout in the fourth inning on Wednesday at Kansas City after shouting his displeasure to home plate umpire Dan Bellino.
Arenado came up with one out and a runner on first and the Rockies leading 2-0 in what would become a 3-1 victory.
"I just got upset," Arenado said. "That's all I can say. I thought it was a little low. But, hey, he's working, too. He's trying to get things right. I apologized. Just got caught up in the moment, but it's part of the game.
"I said a bad word and he said, 'You're gone.' Obviously, it's unfortunate. I probably shouldn't have said that bad word. But like I said, I was upset, caught up in the moment."
Asked whether Buckminster or Arenado went too far, Rockies manager Walt Weiss said, "It's hard to say. Nolan was frustrated right there, obviously. A pitch earlier in the at-bat kind of got him going and then strike three. I don't know exactly what was said, but he did what he did."
Cuddyer expected to come off DL on Tuesday
DENVER -- Right fielder Michael Cuddyer (left hamstring strain) is on track to be activated Tuesday when the Rockies open a series against the Giants.
He played seven innings at first base and batted seven times in an extended spring game on Friday.
Rockies trainer Keith Dugger said, Cuddyer, who was injured April 17, "feels normal and is 100 percent."
Dugger said Cuddyer is scheduled to play at least seven innings in the outfield and bat a minimum of seven times Saturday in another extended spring game before then flying to Denver. The plan is for Cuddyer to then play a rehab game Sunday at Triple-A Colorado Springs.
In 16 games this season, Cuddyer is hitting .317 (19-for-60) with three homers and 10 RBIs.
Rosario slated to rejoin Rox on Sunday
DENVER -- Catcher Wilin Rosario will likely be activated on Sunday when he is eligible to come off the 15-day disabled list.
He went on the DL retroactive to May 3 with Type-B influenza and ran a temperature as high as 103 degrees.
Rosario played in a rehab game Friday at Triple-A Colorado Springs and is scheduled to play there again Saturday. At the time he became ill, Rosario was hitting .239 (21-for-88) with three homers and 15 RBIs in 24 games.
Weiss shrugs off influx of strikeouts on road trip
DENVER -- On their 2-5 road trip that ended Wednesday and included stops in Texas, Cincinnati and Kansas City, the Rockies struck out 60 times. They had at least eight strikeouts in the final six games and 33 strikeouts in the last three contests, which were started by Homer Bailey of the Reds and James Shields and Jason Vargas of the Royals.
Manager Walt Weiss wasn't concerned by the number of strikeouts, calling them a "cyclical" event that will occur during the course of a long season.
"I think we ran into some tough pitching," Weiss said. "That's a part of it. But we just weren't as sharp offensively. We've been real good most of the year offensively, so I feel confident that it's not going to get away from us for too long. You're not going to score eight, nine runs in this league every night. It's impossible. So there's going to be times where we struggle offensively and good pitching can shut you down."
• Right-hander Tyler Chatwood (strained right flexor tendon) is pain free and working on range of motion exercises. Trainer Keith Dugger said Chatwood had a series of platelet rich plasma injections and will likely have another, possibly on Monday. He could start a throwing program toward the end of next week. Chatwood is on the 60-day disabled list and is eligible to be reinstated June 29.
• Reliever Rafael Betancourt, who underwent Tommy John surgery in September, threw his second bullpen session Friday, a 20-25 pitch effort. He could be ready to begin a rehab assignment around the start of July. That stint would see him pitch at every Minor League level and he could pitch for the Rockies this season. Betancourt was the Rockies' closer the past two seasons, earning 31 saves in 2012 and 16 last season when he went on the DL three times.
• Left-hander Brett Anderson, who suffered a fractured left finger on April 12 and is on the 60-day DL, is about two weeks away from having the pins removed from the finger. He isn't expected back until around the All-Star break.
• The Rockies are giving away bobblehead gnomes at select Sunday home games, and a likeness of Carlos Gonzalez will given to the first 15,000 fans on Sunday.
"I look like a Chinese gnome," Gonzalez said. "I think it's fun. That's what the fans like. They like to come to Coors Field and get a gift and of course watch the Rockies win ballgames."
