San Francisco Giants right-hander Justin Verlander will be placed on the 15-day injured list due to a right pectoral injury, manager Bob Melvin said after Wednesday's 8-4 loss to the Kansas City Royals.

San Francisco Giants manager Bob Melvin said that Justin Verlander was dealing with a little bit of a pectoral muscle issue during his start Sunday, but — like Verlander — he’s optimistic Verlander will make his next start.

The Giants are off Thursday, so Verlander can get some extra treatment if he is to start Saturday in Washington, D.C. If he's not ready, there are options. Kyle Harrison is in the bullpen and Jordan Hicks is still stretched out to start if needed.

Verlander (0-3) avoided another loss with help from Heliot Ramos, who drove in the first run in the first inning on a first-pitch home run off A’s starter Jeffrey Springs. Ramos also drove in the go-ahead run in the eighth on a groundball single to left against reliever Tyler Ferguson.

Heliot Ramos hit a leadoff homer in the first inning and had a go-ahead single in the eighth, lifting the San Francisco Giants to a 3-2 victory over the Athletics on Sunday that completed a series sweep.

The San Francisco Giants (27-19) will host the Athletics (22-24), Sunday at 4:05 p.m. ET, with the Athletics on a four-game losing skid. The Giants are favored (-163 on the moneyline to win) when they host the Athletics (+138). The Giants will start Justin Verlander (0-3) versus the Athletics and Jeffrey Springs (5-3).
