Giants place starting pitcher on IL, activate Jorge Soler

The Giants placed starter Keaton Winn on the 15-day injured list, retroactive to May 15, due to a forearm strain. San Francisco also optioned infielder Casey Schmitt to Triple-A Sacramento. They reinstated DH Jorge Soler from the 10-day injured list and recalled righty Mason Black in corresponding moves.

Winn has held a spot in the rotation all season. The rookie righty has taken nine starts, tallying 42 1/3 innings of 6.17 ERA ball. Winn pitched well through his first six appearances before surrendering at least five runs in each of his three most recent outings. While a forearm strain is sometimes an ominous precursor to a significant injury, the Giants don’t seem concerned. President of baseball operations Farhan Zaidi told reporters that imaging didn’t reveal any structural damage and the team doesn’t anticipate Winn missing much time (link via Andrew Baggarly of the Athletic).

Black will take the ball tonight against the Rockies opposite Ryan Feltner. Blake Snell is on a rehab stint and could step back into the rotation next week alongside Logan Webb, Jordan Hicks and Kyle Harrison. Black could hold the final spot until Winn returns.

Soler will lead off tonight in his first action since May 4. He missed just under two weeks with a shoulder strain. One of the team’s biggest offseason acquisitions, Soler is out to a modest .202/.294/.361 start to his Giants tenure. Wilmer Flores had taken the majority of the DH at-bats while Soler was sidelined.

Marco Luciano is starting at shortstop tonight and hitting ninth. It’s the first start of the season for the 22-year-old top prospect. With Schmitt headed back to Sacramento, manager Bob Melvin suggested Luciano is going to play regularly (X link via The Athletic’s Eno Sarris). For much of the offseason, it looked as if Luciano would be San Francisco’s first choice at the position. The Giants added veteran defensive specialist Nick Ahmed late in the winter on a minor league deal and wound up carrying him on the MLB roster.

Ahmed hit .236/.274/.291 through his first 36 games. He went on the injured list with a sprained left wrist last week. While the injury isn’t expected to keep him out for too long, Luciano could get a chance to hit his way into the permanent shortstop job. He had a .266/.399/.344 slash line in 158 plate appearances with Sacramento. Luciano has walked at a massive 18.4% rate in Triple-A, but he’s also striking out at an elevated 27.8% clip. He struck out 17 times in 45 plate appearances last year in his first taste of major league action.
