Locke enters Tuesday's start at PNC Park with an earned-run average more than four runs better at home (3.05) than on the road (7.28). The lefty holds a career 3.14 ERA and 1.28 WHIP in 43 career innings against the Reds. His matchup likely became better when Cincinnati decided to rest expected starter Johnny Cueto (elbow) in favor of rookie Joe Smith. Locke has compiled two of his season's best starts his last two times out, striking out 10 in 12 IP while allowing only two earned runs.
