In four Grapefruit League starts, the right-hander is 0-1 with a 6.00 ERA. He has allowed 19 hits in 12 innings.
"Some things didn't go my way. I kept the ball in the infield like I wanted. I just didn't have it hit to anybody hard enough," Worley said.
The Twins have high hopes for Worley, who slumped to a 6-9 record with a 4.20 ERA last year after going 11-3 with a 3.01 ERA as a Phillies rookie in 2011.
He allowed two runs on four singles and an infield out in the second inning Sunday before giving up J.J. Hardy's first home run of the spring in the fourth. Worley threw 51 pitches before getting a swing-and-miss.
"I don't get a lot of swing-and-misses in general. Everybody says the same thing: `You've got to get more swing-and-misses.' Maybe they should swing at those pitches I want them to swing at. That's really nothing I can do. My job is to get ahead in the count and get them to put the ball in play," Worley said.
Steve Johnson, one of several pitchers competing for the No. 5 spot in Baltimore's rotation, threw four scoreless innings. He allowed three hits and walked one while striking out two.
"It is definitely a heated battle, but it's a lot of fun going out there and competing," Johnson said. "You're not only competing against the other team but you're competing against the other five, six, seven guys or however many we have going after the spot. So it's a lot of fun and it's just an honor to be in the running."
Hardy was 1 for 21 before his home run.
"It was definitely nice to put a barrel to a ball," he said. "I wasn't really worried. We still have a few weeks left. I'll get a few more at-bats. I wasn't too worried about the first 25 (at-bats) or so, but that definitely felt good."
