Losing Matt Chapman to the injured list for the second time this season hurt, but the Giants could at least take some solace in knowing that they had another natural third baseman -- Casey Schmitt \-\- who could replace him in the interim.

Roupp, 26, was placed on the injured list on July 25 (retroactive to July 23) with right elbow inflammation after pitching five shutout innings against the Braves in Atlanta. The Giants said they believed Roupp’s injury was on the minor side, and Roupp only needed one rehab start with Triple-A Sacramento (three innings, two runs) before returning.

In the Giants' tough loss to the Rays at home on Friday, the only good news is X-rays came back negative for both Giants infielders.

His slump has been just one factor in a team-wide offensive shortage over the last month, which has led to the Giants’ big slide down the standings.

Outside the stadium, Summer Abella, a longtime fan from Livermore decked out in Giants apparel, wore a wry smile as she relived the day’s sorrows. The game, she said, was the last gasp for the team’s playoff chances.

BOTTOM LINE: The San Francisco Giants look to stop their six-game home slide with a win against the Tampa Bay Rays. San Francisco has a 29-32 record at home and a 59-63 record overall. The Giants have a 26-44 record in games when they have given up at least one home run.

Joining Roupp on the shuttle from Sacramento is fellow righty Keaton Winn, who joins the MLB squad for the first time this year. Winn lost three months of the season on the IL, and is finally looking healthy. He’s been working in relief while he gets back up to speed, and will continue that role in San Francisco.
