Rosario notched his second homer of the season and drove in two runs in Thursday's 5-4 victory over the Dodgers.

Rosario validated his reputation as a lefty killer, as his second-inning solo shot represented most of the damage the Rockies could muster off of opposing starter Brett Anderson. Though Justin Morneau was bypassed for Thursday's start after leaving a night earlier with a spell of dizziness, he's generally expected to be ready to return to the lineup at some point during the series with the Dodgers, which would likely relegate Rosario to a bench role. However, with southpaw Clayton Kershaw toeing the rubber Friday for the Dodgers, expect Rosario to find himself back at first base again for one more day.

Rosario will get the start at DH Tuesday against the Angels.

This is a rare two-game stretch in the schedule where Rosario's bat can get in the lineup without hurting the Rockies' defense. Colorado will be back in a National League park Thursday and won't visit an American League team again until mid-June.

Rosario started at first base on Sunday and went 2-for-3 with a walk, a run scored and an RBI against the Dogers.

It was Rosario's first appearance since being recalled from Triple-A Albuquerque on Friday as he spelled Justin Morneau with left-hander Clayton Kershaw on the mound. Rosario will likely see limited playing time with Morneau at first and catchers Nick Hundley and Michael McKenry in the fold.

Rosario was recalled from Triple-A Albuquerque on Friday, Nick Groke of The Denver Post reports.

It's still not clear where Rosario fits in, but he'll at least provide the Rockies with a powerful bat off the bench, and he's a nice alternative to Justin Morneau against left-handed pitching. With Colorado facing Dodgers southpaw Brett Anderson on Friday, it seems likely Rosario will start over Morneau at first base.

Rosario was optioned to Triple-A Albuquerque on Wednesday, Thomas Harding of MLB.com reports.

Rosario indicated he was optioned due to extra help needed in the bullpen. He was kind of an odd man out for the Rockies, no longer considered an option as a catcher and stuck behind Justin Morneau at first base. It's a bit surprising that the club hasn't been able to deal him elsewhere, but for now he'll take a spot in the minors and await another opportunity.

Rosario is not listed on the Rockies' lineup card Wednesday, Nick Groke of the Denver Post reports.

Rosario's absence from the lineup card could be an indication of a roster move, as John Axford will need a spot freed up for his return to the bullpen. It's unclear exactly what's going on with Rosario, but a trade isn't out of the realm of possibility. His status should be updated at some point providing more clarification as to why he's not on the card.

Rosario is getting the start at first base Friday, the Denver Post's Nick Groke reports.

With Clayton Kershaw on the mound the Rockies will look to get as many righties in the lineup as possible, so Justin Morneau will get the day off. In just seven at-bats this year Rosario already has a homer and a double, so when he's in there, he can be a solid play, but it would still be risky to start him in daily leagues against Kershaw away from Coors Field.

Rosario ended up coming off the bench Wednesday against the Brewers, delivering a game-winning pinch-hit home run in the top of the 10th inning to lift the Rockies to a 5-4 victory.

Rosario was initially pegged to start at first base Wednesday, but Justin Morneau, who dealing a neck issue, ended up talking his way into the lineup. That didn't stop Rosario from making an impact to those who had him active, as he showcased the kind of power burst off the bench that has made him an enticing target at the catcher spot during his time in the big leagues. While he'll still retain eligibility at catcher in most formats for 2015, Rosario's porous defense behind the plate will result in him seeing most of his duty this season as a pinch-hitter or spot starter at first base when Morneau requires a day off. Rosario should still make for a strong option in daily leagues when he's in the lineup against left-handed pitching, but the lack of guaranteed at-bats he's due to receive on a week-to-week basis will hurt his value in season-long leagues.

Rosario will start at first base against the Brewers on Wednesday, batting sixth, Patrick Saunders of the Denver Post reports.

Rosario lost out to Nick Hundley for primary backstop duties, but could still receive some starts behind the plate and at first base this season. With Morneau out of the lineup Wednesday, his first start will come at first.

Rosario remains out of the lineup for Tuesday's game against the Brewers, Thomas Harding of MLB.com reports.

Nick Hundley is starting at catcher for a second straight day, and it appears he will indeed be the primary option behind the plate moving forward. Manager Walt Weiss said recently that he viewed Rosario as "that half-catcher who plays first base," suggesting Rosario's opportunities may be rather limited. He should still see some time at first against left-handed pitching.

Rosario started at catcher and went 2-for-4 with an RBI at the dish in Tuesday's spring training game against the White Sox.

Rosario has seen less action behind the plate this spring than Nick Hundley and Michael McKenry, but manager Walt Weiss suggested that all three players will open the season on the 25-man roster. However, given Rosario's well-documented defensive shortcomings at catcher the last four seasons, it seems likely that he'll see most of his usage as the team's top pinch-hitting option off the bench and as an occasional lineup replacement for Justin Morneau. Nonetheless, the lack of the guaranteed starting role Rosario enjoyed in the past figures to result in a significant downgrade in at-bats, and by extension, his fantasy value. Moreover, if the Rockies proceed with their plan to use Hundley and McKenry as their primary catchers, Rosario would likely lose eligibility at the position in the seasons to follow.

Rosario has been listed as third on the Rockies' depth chart at catcher this spring, MLB.com's Thomas Harding reports.

This essentially corroborates what has been speculated for months: the Rockies no longer view Rosario as a viable regular behind the plate. Rosario spent most of spring training getting his feet wet at first base, and while his defensive liabilities figure to better hidden at that position, he still doesn't figure to see much more than the smaller half of a platoon with Justin Morneau. The 26-year-old is having a strong spring at the dish with a .381 average and two homers over nine Cactus League games, but it won't do much to halt what seems like an inevitable decline at-bats this season.

Rosario smacked two homers and drove in five runs during Tuesday's split-squad game against the Mariners.

Though spring training statistics should often be taking with a grain of salt given the high number of minor-league caliber players participating, Rosario's blasts came off lefty Roenis Elias and right-hander Dominic Leone, two pitchers who spent most of last season in the majors and project to make the Mariners' Opening Day roster. Rosario has been the focal point in trade rumors for much of the past few months due to his lack of development behind the plate, and it appears the Rockies remain unsold on the idea of him seeing much duty as catcher, as he's manned the position in just one of his six Cactus League games thus far. That being said, the 26-year-old's game-changing power may just convince the Rockies to keep him around as a weapon off the bench, if nothing else.

Rosario reported to the Rockies' spring training complex early, where he'll spend significant time working on fielding grounders at first base, the Denver Post reports.

While his role behind the plate is diminishing, Rosario will likely still be in the mix to catch for the Rockies if needed, but he's going to have a chance to serve as the primary backup to Justin Morneau at first base. Further, the Rockies could use Rosario at first on days when the team is facing a left-handed starter, as Morneau is ideally suited for a strict platoon.

Rosario lost his arbitration case against the Rockies and will make $2.8 million for the 2015 season, The Denver Post reports.

Rosario struggled offensively in 2014, batting just .267/.305/.435 with 13 home runs and 54 RBI over 106 games. He worked out at first base and in the outfield during the Rockies' academy in the Dominican Republic, and could end up losing his job behind the plate due to his defensive woes and drop in production (along with the addition of Nick Hundley). He will need show a improvement at the plate in spring training to earn himself more playing time, but he also could wind up as a utility man in 2015, limiting his at-bats and his fantasy value.

Rosario was working out at first base and in the outfield at the Rockies' academy in the Dominican Republic earlier this month, MLB.com's Thomas Harding reports.

Despite Rosario's minimal improvement as a backstop across four seasons in the majors, the Rockies don't seem to be cutting bait entirely on the idea of him serving as a catcher for the club. Even so, it's clear that after this winter's signing of Nick Hundley, Rosario no longer appears to be the club's primary catcher, forcing him to showcase his versatility to play other positions in an attempt to augment his value. It's probably for the best that Rosario spends more time at a position where his defense might be less of a focal point, but from a fantasy perspective, the probable downgrade in at-bats that would come with a utility role dampens his outlook. Rosario hasn't helped his cause by seeing his offensive production plummet in successive seasons since his 28-homer 2012 campaign, with his OPS dropping to a career-worst .739 in 2014.

Rockies manager Walt Weiss said Tuesday that Rosario could be used as the right-handed hitting platoon partner for Justin Morneau at first base.

Although he appeared at first base in just four games last season, the Rockies are undoubtedly seeking ways to keep his bat in the lineup without overexposing their team defense by leaning too heavily on Rosario behind the plate. A hand injury sapped Rosario's power last season, but the departure of Michael Cuddyer in free agency could help him return to the neighborhood of 450 at-bats again.

Rosario is not in the lineup for Saturday's game against the Dodgers.

Rosario will get the night off after catching each of the last three games. Mike McKenry will get the start behind the plate in Rosario's place.

Rosario is out of the lineup Monday against the Padres.

Manager Walt Weiss will have the scorching-hot Rosario take a seat Monday, with Mike McKenry getting the nod at catcher. Rosario racked up 14 hits while playing in five of the Rockies' seven games during their recently-completed homestand, but his bat could cool with the team set to close the season in pitcher-friendly environments in San Diego and Los Angeles.

Rosario went 2-for-3 with three runs and a walk in Sunday's win over the Diamondbacks.

There might not have been a better performer over the past week than Rosario, who went 14-for-20 with two homers, nine RBI and eight runs scored while making five starts in the last seven games. The surge has allowed Rosario to make a 24-point climb in batting average during that time, but he'll be hard-pressed to maintain his torrid ways over the final week of the season. The Rockies will travel to San Diego and Los Angeles for three games apiece, playing in parks that are far less favorable than Coors Field, where Rosario spent the last week terrorizing the opposition.
