While Max Scherzer and Clayton Kershaw are hooking up in a marquee MLB matchup in Los Angeles tonight, there’s a Mississippi-flavored clash up the coast in Oakland that also bears watching. Boston, which has roared from the starting gate with a 16-2 record, welcomes former Ole Miss star Drew Pomeranz back from the disabled list. A 17-game winner in 2017, Pomeranz will oppose ex-Mississippi State standout Kendall Graveman, the A’s opening day starter who has struggled to a 9.87 ERA through four outings. (For the record, they did not cross paths in college.) Pomeranz, who suffered a forearm strain in spring training, made two rehab starts — one in Triple-A, the other in Double-A — and posted a 3.72 ERA over 9 2/3 innings. Graveman, who has yielded six homers this season, gets to face a scorching-hot Red Sox lineup (27 runs in three wins against the Angels) that may include State product Mitch Moreland. He has two bombs against Graveman in 12 career at-bats. P.S. JaCoby Jones, the former Richton High star, hit his first career walk-off homer — his first of 2018 — to propel Detroit to a 3-2 win in 10 innings against Kansas City today. Jones is batting .300 in 13 games.
