While other pitchers faced hitters, Bettis loosened up for a bullpen session that would have been solitary. But Nolan Arenado asked to stand in the batter's box to give him a hitter visual. But little of his work was done in the view of fans, who watched the diamonds at Salt River Fields at Talking Stick.
Bettis won't pitch the first time through the Cactus League rotation. He'll throw a simulated game next Tuesday, and after that he'll appear in Cactus League games.
In 2015, Bettis was held out of spring games until late in camp to correct delivery flaws. He has now determined that the early part of camp is more valuable for fundamentals than competition.
"It allows me to focus a little bit more on what I really want to accomplish, and not getting too far from making sure I'm sound with my fastball down and away," Bettis said. "Too early, there are a lot of variables that can pop in there. Being able to focus on perfecting what I want to and getting that down to a tee before I go into competition really benefits me."
Bettis went 14-8 with a 4.79 ERA in 32 starts last year - 8-2, 4.44 in 14 home starts.
Bettis, who turns 28 on April 26, continues to stay in touch with doctors -- he consulted with them during the last couple of days - but so far, so good.
New Rockies manager Bud Black said, "I can't say enough about his mental strength through this, and we'll find out more as we go really, truly where this is headed, and where he is as it relates to baseball. But, man, what a story."
Bettis said, "All the support I've been getting from the fans has been great, nothing but joyous."
