Rotowire: Feb 12 / 4:20p ET
News: Butler (shoulder) received an invitation to the Rockies' major league spring training camp, MLB.com's Thomas Harding reports.
Impact: Butler and fellow top prospect Jon Gray will audition for a rotation spot with the big club, but the team's recent signing of Kyle Kendrick for their No. 5 spot appears to have closed off any legitimate competition from taking place. The 23-year-old struggled in his first exposure to the majors last summer, posting a 6.75 ERA and a 3:7 K:BB ratio over three starts (16 innings) while contending with inflammation of his right rotator cuff. Butler appears to be healthy after using the offseason to recover, but he'll more than likely have to prove his worth at Triple-A Nashville before he receives another appointment to the big leagues.
Rotowire: Feb 5 / 3:52p ET
News: Butler's (shoulder) chances of cracking the big-league rotation out of spring training took a hit following Wednesday's signing of Kyle Kendrick, MLB.com's Thomas Harding reports.
Impact: The addition of Kendrick gives the Rockies a veteran trio of pitchers that includes staff ace Jorge De La Rosa and Jhoulys Chacin, while promising youngsters Tyler Matzek and Jordan Lyles are tentatively penciled in for the final two starting spots. The seemingly full rotation will in all likelihood force Butler and fellow top prospect Jon Gray to pick up some further seasoning at Triple-A Colorado Springs, but either pitcher could earn a quick appointment to the big leagues if their dominance continues at the highest level of the minors. Butler received his first look with the Rockies in July last season when injuries compromised the team's rotation depth, churning out a 6.75 ERA and 1.87 WHIP over three starts.
