Half orc fighter max starting HP

A non-playing friend of mine was looking around in the DnDBeyond website and created a (what I assume was a 1st lvl) character: half-orc with a STR of 19 and CON of 18. He showed me on his phone, but all I saw were the stats, and HP of 18/18. He said it was a fighter. Is there a way to start w/ 18 HP, given these parameters? My calculation was 14 HP.
