Rockies Select Luis Peralta
The Rockies announced that they have selected the contract of left-hander Luis Peralta. In corresponding moves, they optioned right-hander Tanner Gordon to Triple-A Albuquerque and transferred righty Germán Márquez to the 60-day injured list.
Peralta, 23, was just acquired from the Pirates last month in the Jalen Beeks trade. The younger brother of Brewers ace Freddy Peralta, Luis signed with the Pirates out of the Dominican Republic in 2017. He came up as a starter but has been moved into a relief role this year, with some encouraging results.
He has pitched at High-A, Double-A and Triple-A this year between his two organizations. Between all those different stops, he has logged 47 2/3 innings while only allowing five earned runs for a tiny ERA of 0.94. His 11.2% walk rate in that time is a bit high but he’s worked around that by striking out 40.1% of batters that have stepped to the plate.
He was going to be eligible for the Rule 5 draft this winter and was likely going to get a roster spot in a few months’ time anyway, so the Rockies are jumping the gun and adding him now, which will allow them to get a look at him against major league hitters for a few weeks.
Gordon had been working out of the club’s rotation, so they will now have a hole there behind Cal Quantrill, Kyle Freeland, Austin Gomber and Bradley Blalock. Right-hander Ryan Feltner landed on the 15-day IL on August 8 due to a right shoulder strain but could perhaps be coming back. Patrick Lyons of Just Baseball relayed on X last week that Feltner’s MRI came back clean and he could be back after something close to a minimal stint. He made a rehab appearance for Triple-A Albuquerque on Wednesday.
As for Marquez, it was reported a couple of weeks ago that he won’t be coming back this year due to some elbow inflammation, so this transfer to the 60-day IL was an inevitable formality. He’ll be on the 60-day IL for the rest of the year but will need to be reinstated in the days following the World Series, as the IL goes away until Spring Training.
Pirates Acquire Jalen Beeks From Rockies
The Pirates announced the acquisition of lefty reliever Jalen Beeks from the Rockies for minor league reliever Luis Peralta. Pittsburgh had an open spot on their 40-man roster after this afternoon’s trade with the Red Sox.
Colorado claimed Beeks off waivers from the Rays over the winter. Tampa Bay was evidently not planning to tender him a contract for his final season of arbitration. Rather than allow him to hit the market, Colorado took a flier and agreed to a modest $1.675MM salary. Beeks has had a generally productive season. He’s second on the Rox with 49 1/3 innings out of the bullpen and has pitched in their highest-leverage spots overall.
Beeks has worked to a 4.74 ERA in 45 appearances. He’s carrying a career-low 18% strikeout rate and 9.2% swinging strike percentage. Beeks has a league average 8.5% walk percentage and 44.7% grounder rate. He somewhat bizarrely had far more success at Coors Field than he did on the road for the Rox.

Pittsburgh plugs him behind Aroldis Chapman as the second lefty in Derek Shelton’s bullpen. They’re assuming roughly $500K in salary for the stretch run. Beeks will surpass the six-year service threshold in September and hit free agency at the beginning of the offseason. Colorado didn’t have much incentive to keep him, so they’ll cash him in for an intriguing bullpen prospect.
Peralta, 23, is the younger brother of Brewers staff ace Freddy Peralta. The 5’11” southpaw signed with Pittsburgh out of the Dominican Republic in 2017. Peralta has divided his season between High-A and Double-A, turning in a 0.91 ERA over 39 2/3 innings. He’s striking out an eye-opening 41% of batters faced against an elevated 11.5% walk rate. Baseball America had Peralta as the #24 prospect in the Pittsburgh system, writing that he relies heavily on a mid-90s fastball with good life at the top of the strike zone. He’d be eligible for the Rule 5 draft this winter if Colorado doesn’t select him onto the 40-man roster.
