Betancourt, who turns 40 in late April, didn't pitch last season while recovering from an elbow injury, but he was able to land a spot in the Rockies bullpen by giving up just one earned run in 7 2/3 innings while striking out nine and walking one. He'll join closer LaTroy Hawkins, 42, in giving the Rockies' bullpen a pair of the league's eldest statesmen.
Ynoa earned his spot by hitting .309/.333/.364 in 55 spring at-bats.
Petit was reassigned to minor-league camp Sunday after failing to win a major-league roster spot with the Astros. He hit .310/.375/.414 in 29 at-bats this spring.
Panik was scratched from Tuesday's game due to a minor ankle issue but was able to get back into the action just one day later. He has hit .222/.279/.444 with three home runs in 63 spring at-bats.
"The young man, I think, has continually improved," manager Joe Girardi said. "He's a name that I'm sure is going to fly around a lot today."
Refsnyder is hitting .333 with five RBI in 39 plate appearances this spring.
"Things can happen quick," Girardi said. "I think a lot of clubs hold their breath this time of year that you leave camp the way you are. Sometimes it doesn't happen and you've got to deal with it. … Didi and Drew are healthy, so we're going to have to look at probably more of a second baseman in a sense. You could look at a second baseman more than a shortstop because you have two shortstops."
Utley hit a three-run homer off Julio Teheran in the first inning before adding a solo home run off Teheran in the third inning. Utley had two home runs off Tigers starting pitcher Anibal Sanchez on Sunday.
Utley, who was limited to DH duties early in the spring due to a sprained ankle, is batting .448 (13 for 29) with two doubles, four home runs and nine RBI in 11 spring games.
