Let's try to make a list of breakout pitchers and underrated pitchers for 2006 using guys who aren't talked about much.

Mainly looking for guys rated B- or less who will start 2006 in AA or lower who could improve their stock to a B+ with either a breakout year or another solid performance (of course based on past performance and scouting/talent).

I'll start the list off. Ages as of Opening Day 06.

TOR Chi-hung Cheng - Age 20
2005: A(Midwest): 3.15 ERA, 137 IP, 9.33 K/9, 7.16 H/9, 4.73 BB/9
LHP with a plus curveball and 90 MPH fastball with good movement.

CLE Chuck Lofgren - Age 20
2005: A(SAL): 2.81 ERA, 93 IP, 8.61 K/9, 7.06 H/9, 4.16 BB/9
LHP with great movement on 93 MPH fastball and plus potential curveball. Needs work on changeup.

TB Wade Davis - Age 20
2005: SS-A(NYPL): 2.72 ERA, 86 IP, 10.15 K/9, 7.85 H/9, 2.41 BB/9
RHP with great pitcher's body (6-5/220), a mid-90's fastball, and a plus curveball. Needs work on changeup.

TB Jake McGee - Age 19
2005: SS-A(NYPL): 3.64 ERA, 76.2 IP, 10.45 K/9, 7.51 H/9, 2.70 BB/9
LHP with 90 MPH FB, curveball with great movement, and solid changeup. One of the youngest pitchers, but most successful in NYPL.

OAK Dallas Braden - Age 22
2005: Hi-A(Cal): 2.68 ERA, 43.2 IP, 13.19 K/9, 6.39 H/9, 2.27 BB/9
AA(Texas): 3.90 ERA, 97 IP, 6.59 K/9, 9.65 H/9, 2.97 BB/9
LHP with 90 MPH FB, solid changeup, and a screwball which is his out pitch. Great ratios until AA, but I see him getting back around 8-10 K/9. Doesn't allow many HR's or walk many batters, so his stuff should always keep him competitive.

DET Eulogio de la Cruz - Age 22
2005: Hi-A(FSL): 3.39 ERA, 95.2 IP, 9.13 K/9, 6.21 H/9, 3.39 BB/9
RHP reliever converted into starter with 100 MPH fastball. Assuming Detroit pitching coaches are working on a secondary pitch with him, he will post even better K totals and raises his stock... if not, he's just another hard thrower.
