The Philadelphia Phillies have announced that Jeremy Hellickson will be their Opening Day starter, but they still need a closer.

With spring training winding down, several candidates appear to be in the running for the job. Andrew Bailey looks like the front-runner, according to MLB.com's Todd Zolecki, while David Hernandez and Dalier Hinojosa could also be in the mix. Hernandez was believed to originally be the favorite for the job, but soreness in his right triceps has slowed him down.

Bailey, a two-time All-Star as a closer with the Oakland Athletics before injuries derailed his career, started camp with four scoreless outings before giving up three runs to the Minnesota Twins on Tuesday. Bailey is a logical fit for the role if he's healthy, but Phillies manager Pete Mackanin wants to see more zip on his fastball.

"I know he can pitch. He's a true competitor. He has that good curveball and cutter. But I want to see more velocity," Mackanin said.

Meanwhile, Hinojosa is more of a dark horse in the closer competition. The 30-year-old Cuban posted a 0.78 ERA in 23 innings with the Phillies last year and is enjoying a strong spring.

"I go by what I saw from Hinojosa last year and this spring," Mackanin said. "He's aggressive. He throws strikes. He's got that split and a slider. A changeup as well. He's a competitor. He's in the mix. They're all in the mix. It's a big mix."
