just two, while holding hitters to a .226 average.

10. Madison Bumgarner, LHP, San Francisco Giants
Bumgarner won't turn 19 until August and he didn't make his pro debut until this spring, but the Giants still felt confident enough to let the southpaw make that debut with full-season Augusta. After allowing five earned runs over three innings in his first start, he's allowed just five more over the next 19 (2.37 ERA). He's struck out 25 in 22 total innings, while walking six.
