The Mariners enter this series red hot, having won seven straight games and nine of 10 to catapult themselves back into the AL playoff picture. They are just two games back of a playoff spot thanks to sweeps of the San Diego Padres and Los Angeles Angels and a series win over the Boston Red Sox.


The Orioles and Mariners met at Camden Yards near the end of June this year. The Orioles won the series, rebounding from a 13-1 loss in the series opener to win game two 6-4 and game three 3-2 to spoil the Mariners road trip.

Sunday, 8/13: Kyle Bradish vs Bryce Miller

Overall, Bradish's second season has been a successful one. He has a 3.19 ERA, 3.78 FIP, and 1.141 WHIP, averaging 0.9 home runs per nine, 2.6 walks per nine, and 8.3 strikeouts per nine in 115 2/3 innings and 21 starts.

The rookie Miller gets the start for the Mariners. In his start against the Orioles in June, he allowed three runs on six hits and three walks in 4 1/3 innings. Overall, Miller has a 4.20 ERA, 3.95 FIP, and 1.039 WHIP over 16 starts and 85 2/3 innings, averaging 1.4 home runs per nine and 8.9 strikeouts per nine.

This is a good chance for the Orioles to bounce back after a tough series at home against one of the AL's best and continue to fend off the Rays in the AL East race. Let's play some ball!
