Welcome to the Orange and Black, Mike Leake
Duvall went 14-for-73 last season in the bigs.
Leake has a 7.7 WAR in 6 seasons, with 3.0 of that in a 2013 season where he went 14-7.
Here's the mlb.com story --
Giants general manager Bobby Evans tried fruitlessly to acquire Cole Hamels from Philadelphia or David Price from Detroit, All-Star left-handers who were considered the two premier starters among the pitchers considered available before Friday's 1 p.m. PT non-waiver Trade Deadline. Evans said that Hamels waived his no-trade clause to make a deal involving San Francisco possible, but the Phillies reached a tentative agreement with Texas instead. The Giants lacked the Major League-ready starters Detroit wanted in exchange for Price, who went to Toronto for three Minor League left-handers.
"I feel like we've got more depth that will give us a good chance to win, day in and day out," Evans said.
Skeptics might claim that Leake, 27, isn't a significant upgrade over most Giants starters, such as Matt Cain, Tim Hudson and Jake Peavy. San Francisco's starters are 10-2 with a 3.35 ERA in the team's last 15 games but have averaged approximately six innings per outing.
By contrast, Leake worked eight innings in three of his last four starts, winning all of them and recording an 0.60 ERA in that span.
"We've been in touch with Cincinnati about Leake since Day One," Evans said.
