4) Mike Leake
Like Ian Kennedy and Yovani Gallardo, San Francisco Giants free agent starting pitcher Mike Leake is one of the most durable arms in the MLB. He has started at least 22 games in every season since debuting in 2010.
Leake has been the steadier presence, though, which is why he ranks at No. 4.
The former Cincinnati Red has only had two seasons with an ERA above 4.00, both of which coming in his first and third seasons in the MLB. He has since compiled four straight years of an ERA below that mark while never having a WHIP above 1.25.
With big names like David Price, Zack Greinke and Jordan Zimmerman off the market, Leake will be in demand soon. He seems likely to stay in the NL West, possibly being retained by the Giants or heading to Southern California to play with the Los Angeles Dodgers. They are in need of rotation help with the Diamondbacks signing Greinke.
Where Leake goes will be interesting to follow as MLB free agency continues.
