Adams (0-1) allowed six runs on eight hits and three walks while striking out one over 4.1 innings to take the loss versus the Padres on Wednesday.

2d agoRotowire

Adams was under the five-inning mark for the third time in five starts in the majors, and this was his worst outing yet. While he gave up just two extra-base hits, the Padres were able to pick him apart, racking up at least one run in four of the five innings Adams pitched in. Through 23 innings, he has a 5.09 ERA, 1.65 WHIP and 23:12 K:BB as well as six home runs allowed. Adams is projected to make his next start at home versus the Diamondbacks.

Adams didn't factor into the decision in Friday's 6-2 loss to the Tigers, allowing one run on two hits and three walks over five innings. He struck out five.

The rookie right-hander continues to give the Rockies quality innings, and through his first 18.2 big-league frames he sports a 3.38 ERA, 1.45 WHIP and 22:9 K:BB. Adams is still looking for his first win -- all four of his starts so far have resulted in no-decisions -- and he's served up five homers despite making only one start at Coors Field, suggesting his luck could run out soon. With Kyle Freeland (neck) potentially set to return from the IL next week, however, Adams could get bumped to the bullpen before it does.

Adams allowed three runs on eight hits and a walk while striking out seven over 4.2 innings in a no-decision versus the Cardinals on Saturday.

Adams logged the highest strikeout total of his three starts so far, but his Coors Field debut was otherwise unimpressive. All three runs he allowed came on homers, as Joshua Baez hit a solo shot in the second inning and Ivan Herrera added a two-run blast in the fifth. Adams is now at a 3.95 ERA, 1.61 WHIP and 17:6 K:BB through 13.2 frames in the majors. He's projected to make his next start at Detroit.

Adams did not factor into the decision Sunday against Atlanta, allowing two runs on five hits and two walks over five innings. He struck out five.

Both runs charged to Adams came in the third inning -- Sean Murphy led off the frame with a solo home run before Ronald Acuna drove in a second with a two-out hit. Overall, Adams has been solid through his first two major-league starts, allowing three runs on eight hits while striking out 10 over nine innings. If Kyle Freeland (neck) is unable to return, Adams would line up for a home matchup with the Cardinals his next time out.

Adams is slated to start for the Rockies in Sunday's game in Atlanta.

Adams will receive a second turn through the Colorado rotation after striking out five and yielding one run on three hits and three walks over four innings in a no-decision during his MLB debut Tuesday in a 3-1 win over the Nationals. Though he's a placeholder in the rotation for the injured Kyle Freeland (neck), Adams could have the opportunity to make additional starts for the Rockies over the balance of the season if he acquits himself well in his subsequent outings.
