Rick Porcello has had a decent bit of success for a guy who just turned 24 this past offseason. He has 48 career victories and has reached double-digits in wins in each of his four seasons in the majors.

But it has been a bumpy ride at times. Porcello hasn't had an ERA lower than 4.59 since his rookie season and has seen his WHIP climb higher each year as his career has progressed.

Is this the year that he puts it all together? That's certainly possible.

When looking for a member of the pitching staff for the Detroit Tigers who might have a breakout season in 2013, Porcello seems like as good of a candidate as anyone. He has looked like a different pitcher this spring.

"The life on his pitches, his stuff, plus the command he has, there's a difference there," catcher Alex Avila said. "I think his new delivery and everything that he's worked on has allowed him to really trust throwing that four-seam (fastball) anytime and not relying so much on that sinker."

Grapefruit League statistics don't mean much, but how a pitcher throws certainly does. Porcello has shown good command of his pitches and has effectively used his curveball, which he is throwing in place of the slider he used ineffectively last season.

"Probably the biggest difference is his breaking ball," Avila said. "Working on just one pitch, trying to perfect that pitch, I think that's a smart thing. His curveball is a legitimate out pitch now."

Porcello has put together an impressive pitching line this spring: 24IP, 18H, 8R, 8ER, 0BB, 21SO. He finished Grapefruit League play 4-1 with a 3.00 ERA.
