Peguero had four hits, including a two-run homer, in the Mariners' 9-8 loss to the Colorado Rockies on Tuesday.
''A nice day for him. He's definitely starting to figure it out,'' Seattle manager Eric Wedge said. ''Overall he has had a nice spring.''
Peguero collected his fifth spring homer and three singles. He was sent to the minors last week, but he was recalled when Mike Carp went on the 15-day disabled list and now is a part of the Mariners' crowded outfield picture.
Munenori Kawasaki, Kyle Seager and Casper Wells had two hits apiece for the Mariners, who committed five errors, including two on one play.
Jonathan Herrera had three RBIs for the Rockies, who scored four times in the sixth inning to take the lead. Relievers Rafael Betancourt, Matt Belisle and Rex Brothers combined for three innings of one-hit ball.
''We wanted to get some work for them so it worked out nice,'' Colorado manager Jim Tracy said of his bullpen. ''You can't ask for much more than that.''
Juan Nicasio, Colorado's No. 3 starter, allowed four runs and eight hits over 4 1-3 innings in his worst outing of the spring.
''I just couldn't throw my fastball for strikes. It was either two inches inside or two inches outside,'' Nicasio said.
NOTES: Colorado SS Troy Tulowitzki did not play, and likely won't until opening day Friday in Houston. Tulowitzki was hit on the left elbow by a pitch from former teammate Ubaldo Jimenez on Sunday. ... Seattle optioned reliever Shawn Kelley to the minors, reducing its roster to 27.
