I wrote an off-day story on Orioles rookie outfielder
Avery has shown he can do a lot. His speed is second to none on this roster. His plate discipline is good given his age, and should continue to get better. Orioles manager
But Avery's staying power will likely depend on one thing: his ability to hit left-handed hitters. It's something he has worked on and has improved on, but he still needs to improve there to become a legitimate everyday player.
His splits as an Oriole are dramatic. Avery is hitter .314/.368/.486 against right-handed pitching but just .111/.273/.111 against lefties. All five of his extra-base hits (four doubles, one triple) have come off righties. He also had four strikeouts in nine at-bats against lefties (just four in 35 at-bats against righties).
Like Showalter said, Avery will have some obvious growing pains at the big league level -- like Wednesday, when he was thrown out trying to steal third to end an Orioles rally -- but Showalter seems OK with that given the energy Avery can bring. He doesn't want to "overcoach" a guy like Avery.
But it's Avery's bat against lefties that will truly determine his big-league future.
