CINCINNATI (CBS / AP) -- The Reds have shipped starter Mike Leake to the San Francisco Giants for a pair of prospects, bolstering the defending World Series champions for another playoff run.

San Francisco needed one more solid starter, and got a young pitcher who has been at his best in July. The 27-year-old Leake has won his last four starts, allowing only two earned runs in 30 innings overall.

He threw eight innings of four-hit ball in a 4-0 win in St. Louis on Tuesday.

The Reds got infielder Adam Duvall and right-hander Keury Mella for Leake, who can become a free agent after the season.

The deal came six days after Cincinnati dealt ace Johnny Cueto to Kansas City for three minor league pitchers.
