The San Diego Padres have signed supplemental first-round draft pick Zach Eflin, reports Dan Hayes of the North County Times. According to Hayes, Eflin will sign for $1.2 million; that is below MLB's recommended slot signing bonus for the 33rd overall draft pick, which is valued at $1.5 million. The deal is pending a physical.

ESPN's Keith Law writes Eflin's a pitcher who throws "90-95 with a plus change but needs to junk the knuckle-curve for a more traditional grip."

Hayes also reports the Padres are close to a deal with St. John's outfielder Jeremy Baltz, who the club selected with their second round draft pick.

The Padres earned the 33rd overall draft pick as compensation once Heath Bell signed with the Miami Marlins this past offseason to be their new closer. San Diego has has also just signed their top pick in this past year's draft, 7th overall pick Max Fried. Like Fried, the right-handed pitcher Eflin is a High School player. They now have a pair of first-round draft picks unsigned.
