Possible late add to draft

The Giants are involved in a bizarre addendum to the June amateur draft that could bolster their minor-league system.

The club hopes by Wednesday to complete a physical on Texas high school pitcher Jack Conlon, whom the Orioles selected in the fourth round but did not sign because he failed their physical.

Conlon, who had an offer to play for Texas A&M, became free to sign with any club and reached a tentative agreement with the Giants.

Does that mean they are buying damaged goods? Not necessarily. The Orioles are known for their strict standard for physicals, which has led to several free-agent deals falling apart.

All athletes, even high schoolers, have some degree of physical deterioration. The question becomes about how bad it is and how much financial risk teams are willing to take as a result.

It was not clear why Conlon failed Baltimore’s physical or how large a bonus the Orioles had offered him. The slot value for his pick was just more than $400,000. Baseball America, which said the right-hander has a fastball in the low-90s that can touch 95 mph, reported he wanted closer to $1 million.

Giants officials declined to comment because a deal had not been completed. Their physical is not a formality, but a person familiar with the situation said team doctors will draw their own conclusions and not be influenced by what the Orioles’ doctors found.

First-base options: Brandon Belt returned to the lineup after a two-game absence with a wrist injury. Jae-Gyun Hwang made his big-league debut at first base Monday night after considerable time at the position at Sacramento and did not look nearly as comfortable as he has at third base.

His throwing error on a bunt allowed the go-ahead run to score in a 5-3 loss to Cleveland.

Asked if he might play Hwang at third and Eduardo Nuñez at first if both were needed again on the infield, manager Bruce Bochy said no.

“It doesn’t matter who I put out there other than Buster (Posey). I don’t think he’s going to be completely comfortable,” Bochy said.

Briefly: Bochy plans to start rookie infielder Miguel Gomez and Kelby Tomlinson on Wednesday, the latter possibly playing left field with either Denard Span or Hunter Pence getting a day off. Posey is expected to sit as well. … The Giants activated third baseman Ryder Jones from the disabled list and optioned him to Sacramento.
