4:25pm: In addition to Ruiz, Veras and Smith, the Rockies are also pursuing Brian Wilson, Renck reports in a new article. Colorado is prioritizing power arms to serve as a safety net for Rex Brothers or in order to use Brothers in a setup role where he could match up against lefties in tough situations.

Wilson returned on a $1MM contract with the Dodgers late in the season and totaled 19 2/3 innings between the regular season and the playoffs, allowing just one run and posting a 21-to-6 K/BB ratio. Earlier today it was reported that the Rockies are also interest in Grant Balfour.

9:10am: With Matt Belisle back in the fold after both he and the Rockies exercised their half of his $4.25MM option, the Rockies are eyeing right-handers Jose Veras and Joe Smith as pieces to help fix what was the worst bullpen in the NL last season, reports Troy Renck of the Denver Post. Perhaps more interestingly, Renck adds that the Rockies are continuing their pursuit of backstop Carlos Ruiz and plan to offer him a multiyear contract this week.

The Rockies currently have Wilin Rosario at catcher, but bringing in Ruiz would allow them to give Rosario some additional at-bats at first base and perhaps in right field, writes Renck. The team considers Ruiz to be a clear defensive upgrade over Rosario, although one would imagine that Rosario wouldn't exactly be a swift defender in the outfield should be find playing time out there (then again, neither is incumbent Michael Cuddyer).

Smith, who turns 30 next March, is likely appealing to the Rockies due to his career 57.2 percent ground-ball rate. That number dropped much closer to the league average in 2013, checking in at 49.1 percent, but Smith compensated to an extent by topping his career rates in strikeouts (7.7 K/9) and walks (3.2 BB/9). Overall, his ERA sat at 2.29 in 63 innings of work the the Indians.

The 33-year-old Veras posted a career-best 3.02 ERA with 8.6 K/9, 3.2 BB/9 and a 41.2 percent ground-ball rate in 62 2/3 innings between the Astros and Tigers. Detroit made the surprising decision to buy out his club option last week, making an eighth team in nine seasons a very real possibility for Veras.

The Rockies' 4.23 bullpen ERA in 2013 was the worst in the National League and the third-worst in all of Major League Baseball. The team has already lost former closer Rafael Betancourt to Tommy John surgery, and last offseason's acquisition of Wilton Lopez didn't work as planned, as the former Astro pitched to a 4.06 ERA with a career-low 5.7 K/9 rate in 75 1/3 innings. Lopez figures to return along with Belisle, Adam Ottavino and likely closer Rex Brothers.
