Rosario hit a solo homer as part of a 2-for-3 effort in Tuesday's loss to the Pirates.

EDGE Analysis

Rosario was filling in at first base for Justin Morneau, who took a seat with lefty J.A. Happ on the mound for the Pirates. Look for the Rockies to continue to deploy a platoon at first base the rest of the season, though Rosario stands to see the shorter end of the timeshare.

Rosario singled twice and drove in two runs during Thursday's 11-3 win over the Giants.

EDGE Analysis

Rosario surprisingly picked up the start at first base with a right-hander in Ryan Vogelsong on the mound, but he acquitted himself well while manning the eighth spot in the batting order. The Rockies' decision to move Rosario to first base has largely been a failed experiment, as the former catcher has been rough defensively while seeing his power decline to career-low levels. Playing time may only grow scarcer for Rosario with Justin Morneau (concussion/neck) poised to return soon, and it wouldn't be surprising if the Rockies elected to cut ties with him entirely during the offseason.

Rosario was recalled from Triple-A on Tuesday.

EDGE Analysis

Rosario saw very limited action after the All-Star break, and he was optioned back to Triple-A at the end of July. The 26-year-old has fared well in Albuquerque, hitting .297 in 38 games, but he won't have a clear path to consistent playing time at the big league level.

Rosario is out of the lineup Wednesday against the Angels. Rosario got the start at first base Tuesday, going 1-for-4 with a double. He'll be replaced at first base by Ben Paulson, who will bat sixth in the lineup against right-hander Matt Shoemaker.

Rosario is out of the lineup Sunday against the Diamondbacks, Patrick Saunders of the Denver Post reports. Rosario had started back-to-back games at first base, going 1-for-7 with three strikeouts over that span. He'll give way to Ben Paulsen on Sunday, as the two continue to battle for reps in the absence of Justin Morneau (concussion).

Rosario went 1-for-3 with a walk and a two-run double in Friday's 4-3 loss to the Diamondbacks. Rosario received the start at first base over Ben Paulsen even with the right-handed Chase Anderson on the mound for the Diamondbacks, and the lineup decision paid off immediately when he sparked a three-run first inning with the double. The Rockies weren't able to score Rosario when he led off the top of the 10th inning with a walk, but the loss nor the team's recent offensive struggles don't fall on his shoulders. Rosario has been one of the more productive hitters through eight games of the Rockies' 10-game road trip, going 7-for-22 with two doubles, three RBI, and two walks.

Rosario went 2-for-3 with a double and an RBI Saturday, getting another start at first base despite the Rockies facing right-hander Tim Lincecum. That's four multi-hit performances in four starts for Rosario, whose hot bat has caused the Rockies to move away from a platoon with Ben Paulsen at first base. Once Rosario cools down though, expect him to start seeing the bench more often against same-side pitching.

Rosario went 3-for-4 with an RBI, a run scored, and his second stolen base of the season in Thursday's win over the Diamondbacks. Rosario started all three games of the series against Arizona and submitted a 7-for-11 showing at the plate that included three RBI. His productivity will likely slow down as the Rockies embark on a three-city, 10-game road trip beginning Friday, but for the time being, Rosario looks like he'll serve as the team's primary first baseman.

Rosario went 2-for-3 and connected on a double and a home run in Tuesday's 10-4 win over the Diamondbacks. Manager Walt Weiss typically prefers to utilize Rosario against lefty pitchers, but with the Rockies down two outfielders in Corey Dickerson (foot) and Carlos Gonzalez (knee), Ben Paulsen was forced to make the start in left field. That paved the way for Rosario to slot in at first base against Chase Anderson, and he didn't disappoint, notching his first extra-base hits since his two-homer game against the Marlins on June 6. Though not a righty masher by any means, Rosario is at least slashing a so-so .269/.278/.487 against them this season.

Rosario is batting fourth for the Rockies against the Astros on Monday, Thomas Harding of MLB.com reports. Rosario and Ben Paulsen have been sharing the workload at first base for the injured Justin Morneau (concussion) and it appears that Rosario will get the lion's share of plate appearances Monday. With just one hit over Colorado's past eight games, however, Rosario is a notch below Paulsen's production as Paulsen has five hits over that same time span.
