3 studs and 3 duds: Baltimore Orioles lineup

Baltimore Orioles three studs and three duds
Dud: Ryan McKenna, OF
Yes, Ryan McKenna doesn't play a whole lot, because he's a backup outfielder. But when he has played, he hasn't done a whole lot this season. He's got just a .231 batting average and .620 OPS, going homerless with just two RBIs in 11 games. He also directly led to the Orioles losing the second game of the season to the Boston Red Sox with a dropped fly ball in left field. He's got to pick it up when he gets his chances, because Kyle Stowers is in Norfolk waiting for his next shot.
Dud: Anthony Santander, OF
For someone who was such a key cog to the Venezuela lineup in the World Baseball Classic, Santander has not helped himself to start the MLB season. He's managed just one home run and six RBIs to open the season, slashing .206/.292/.333 to go with a -0.4 bWAR in 16 games. For someone that relies a lot on the long ball, Santander has to step things up.
Dud: Terrin Vavra, UTIL
The main knock on Vavra I have is that he just isn't playing a whole lot. I believe success will come with more playing time. However, he hasn't done a lot with his opportunities. He has just a .200 average and .304 on base percentage, with no home runs and no RBIs in 10 games entering Friday. Like Santander, Vavra is also a negative bWAR player at this point in time, with a -0.1 mark.
