SAN DIEGO -- The Rockies have lined up their top two starters, lefty Kyle Freeland and righty German Márquez, for their games at Coors Field on Thursday and Friday.

Manager Bud Black announced Monday that righty Chad Bettis (0-2, 8.78 ERA in three starts) will pitch out of the bullpen temporarily to accommodate the schedule for the first two games of a four-game set with the Phillies.

The Rockies made the move while activating righty Antonio Senzatela from the 10-day injured list (infected blister on his right heel) to start Monday against the Padres. Senzatela kept his arm in shape during rehab and made two injury rehab starts for Triple-A Albuquerque. He posted a 2.57 ERA in seven innings. The last one was two innings on Thursday, as the Rockies wanted him to be available for Monday’s start.

There was some question about Freeland’s availability. He left a start Saturday at San Francisco after five innings because of a blister on his left middle finger. Freeland has endured three straight losing decisions for just the second time in his career; however, Black said he is healing properly.

Iannetta can’t fathom what Robinson went through
Catcher Chris Iannetta went to the 10-day injured list with a right lat strain sustained during Saturday’s loss to the Giants. He discussed his appreciation for Jackie Robinson, whose breaking of baseball’s color barrier was celebrated Monday with all MLB players wearing No. 42.

Iannetta is active and engaging on Twitter but doesn’t mind calling out snarky and abusive folks every now and then. But the constant abuse that Robinson took on and off the field, and in society, and the constant scrutiny defies anything Iannetta can imagine, even in this world where well-wishers and vicious critics can hit the send button at any time.

“It’s hard enough to play baseball,” Iannetta said. “But to have that much pressure on you, to be in the spotlight and any time you mess up it’s going to be magnified because of the situation.

“I couldn’t imagine what that pressure was like on a day-to-day basis. I couldn’t imagine what conversations were like behind closed doors or with your family and friends in the face of that kind of treatment. It wasn’t just society. It was teammates. It was everywhere.

“If anybody ever nailed it with dignity, it was him. Baseball players now get a small dose on social media. Whether you’re doing well or doing poorly, people can be extremely harsh. But that’s extremely mild compared to what he had to deal with. I draw a parallel, but there is not one considering what he and his family had to go through. He had the foresight to break a barrier and be the focal point of everything. I can’t even wrap my head around it.”

Injury updates
• Lefty Tyler Anderson, who struggled in two starts before going to the injured list with left knee inflammation, pitched Monday in extended spring training. “The knee felt great, threw the ball fine down in extended spring,” Black said. “But, more importantly, the knee was no issue at all for Tyler and he felt good about where he is physically.”

• Outfielder David Dahl is improving from the left midsection injury that cropped up on April 7. He is scheduled to play a game at extended spring training Tuesday. He is eligible to return from the injured list Thursday.
