Locke, who has allowed 18 earned runs in 8.2 innings his last two starts, will square off against the Giants' Madison Bumgarner on Monday.

EDGE Analysis

Locke holds a 3.94 ERA and 1.28 WHIP in 32 innings at PNC Park in 2016. He surrrendered six earned runs on 11 hits and two walks over five innings last September at home against San Francisco. While it may appear the lefty is fighting for his starting spot, Pittsburgh has shown more faith in Locke than he probably deserves.
