Mariners left-hander James Paxton (left forearm) is scheduled to start Wednesday vs. the Colorado Rockies, reports Bob Dutton of the Tacoma News Tribune.

The news comes after Paxton took the mound in a rehab outing with Double-A Arkansas on Friday. The 28-year-old struck out five and allowed two runs and five hits over four innings in the team's 4-2 win over the Frisco RoughRiders.

In an interview with Arkansas Travelers broadcaster Steven Davis on Saturday, Paxton said his Friday start "felt really good" and called it "a good step forward."

Paxton was one of baseball's top pitchers in the opening month of the season, posting a 3-0 record, 1.43 ERA and 0.98 WHIP with 45 strikeouts in 37 2/3 innings. He was put on the disabled list after a May 2 start against the Los Angeles Angels.

After the Mariners finish their series in Boston on Sunday, they'll travel to Coors Field for a two-game series before returning home to begin an 11-game homestand against the Rockies on Wednesday.
