With his strong first half of the season, Peavy should receive the honor as the last man on the ballot for the American League.
Peavy's performance to this point has been significantly better than the other pitchers who are in the running. His earned run average (2.96) is 0.47 lower than that of Jason Hammel (3.43) and 0.63 lower than that of Yu Darvish (3.59).
While the White Sox hurler hasn't struck batters out at as high a rate as Darvish and Hammel, his control is much better than both. Peavy has issued 1.9 walks per nine innings and has a 4.21 strikeout-to-walk ratio.
Hammel has allowed 3.1 walks per nine innings and has a 2.85 strikeout-to-walk ratio. Darvish has allowed an outrageous 4.6 walks per nine innings and has a lackluster 2.21 strikeout-to-walk ratio.
Also, the 11-year pro has lasted longer in his starts than Hammel and Darvish. Peavy averages seven innings per start, while Darvish averages 6.4 and Hammel averages 6.2.
By the way, the 31-year-old is tied for second among AL pitchers with a 3.9 bWAR on the season, compared with 2.4 for Hammel, who ranks eighth, and 2.3 for Darvish.
The relief pitchers in the running haven't shown the level of control that Peavy has. Ernesto Frieri's ice-cold ERA doesn't match well with his dismal 4.8 walks-per-nine-innings rate. Jonathan Broxton has allowed 3.5 walks per nine innings.
When looking at other advanced metrics, the former Padres starter is head and shoulders above the rest. He's fourth in adjusted-pitching wins (1.7), situation-wins saved (2.0) and third in base-out runs saved (18.13).
Peavy has resurrected his career in an impressive way. He's reinvented his form and made himself one of the most outstanding pitchers in the league. His hard work to come back should be rewarded with a place on the AL All-Star team.
