The month of May continues to be a struggle for the Colorado Rockies (15-24), who have now won only 4 times and lost 13 this month, after falling again to the Seattle Mariners (18-24) 10-3 yesterday in Denver. The final game of the interleague series is this afternoon at 1:10 at Coors Field (TV: Root Sports).

In his first career start at Coors Field, Christian Friedrich yielded eight runs on nine hits, including a homer, and four walks. The Rockies have lost 12 of their last 15 games. For the Rockies to contend, pitchers without significant big-league experience, like Friedrich (1-1), must become stalwarts. But with inevitable days of hard lessons like Saturday, it's beginning to look like a tall order to expect that maturation in time for the Rockies to push for the postseason.

It's not only Friedrich, but Juan Nicasio (2-1, 4.37 ERA), whose rookie season last year was shortened by a broken neck, Alex White (0-3, 5.09), who began the year at Triple-A Colorado Springs, and even left-hander Drew Pomeranz, who is at Colorado Springs working on his delivery. This youthful group should include Jhoulys Chacin (0-3, 7.30) in his second full season, but he pitched poorly through right shoulder pain and has landed on the disabled list.

By no means blameless for Saturday was a veteran-laden lineup that made Justin Vargas (5-3) look dominant for seven innings a day after being shut out and held to two hits by former Rockies pitcher Kevin Millwood. Their lack of production during the 1-3 homestand, on the heels of a low-scoring, 2-6 road trip has raised much ire among the faithful. Cheering for Jordan Pacheco's RBI single was part sarcasm. Wilin Rosario followed that with a two-run shot for his sixth homer of the season.
